TL;DR —Abavelisi be-elektroniki baseJapan aba-odola imicu yentsimbi engagqwaliyo eqhotsiweyo evela eTshayina ukuze kusetyenziswe i-spring clip kunye ne-connector terminal stamping baqinisekisa ukuba kukho iitshekhi ezintlanu ezinemilinganiselo kunye ne-metallurgical ezidlula ubuncinci obuqhelekileyo be-ASTM A240 okanye i-JIS G 4305. Eyona nto ixhaphakileyo endiyibonayo kumaqela e-QA aseJapan kwinqanaba lokuhlola elizayo kukuqina kobunzima — umcu we-1/4H ochazwe kwi-HV 250–310 akufuneki ube nobubanzi obungaphezulu kwe-±15 HV kubude be-coil (ukusasazeka kwe-HV 60 okuqhelekileyo kuthathwa njengobubanzi kakhulu kwi-terminal contact spring efuna amandla okuphinda alayishwe kwangaphambili e-±5%). Uburhabaxa bomphezulu kufuneka bube ngaphantsi kwe-Ra 0.5 μm kwicala loqhagamshelwano lomcu we-terminal, kwaye ukunyamezelana kobukhulu kufuneka kubanjwe ku-±0.03 mm kwi-0.3 mm nominal gauge — umahluko we-0.05 mm kubukhulu bomcu uvelisa umahluko we-0.3 mm kubude obukhululekileyo be-spring clip eyenziweyo, etshintsha uxinzelelo loqhagamshelwano nge-1.2–1.5 N ukusuka kwixabiso elichaziweyo. Eli nqaku ligubungela iiparameter ezintlanu zokuhlola ezibalulekileyo xa i-OEM ye-elektroniki yaseJapan ibeka iodolo ephindaphindiweyo yestrip yentsimbi engagqwaliyo eqengqelekayo ebandayo.
Ishishini lokuvelisa izihlanganisi kunye neeterminal laseJapan — iinkampani ezifana neJAE (Japan Aviation Electronics), iHirose Electric, kunye necandelo le-elektroniki likaYazaki — lisebenzisa amawaka eetoni zestrip yentsimbi engagqwaliyo ecociweyo ebandayo ngonyaka kwizinto ezistampuweyo: ii-spring clips ezigcina isiqingatha sesconnector esihambelanayo (ngesiqhelo ubukhulu be-0.2–0.4 mm, 1/2H temper, 301 okanye 304 grade), kunye neesignali okanye iiterminal zamandla ze-0.15–0.30 mm ubukhulu kwi-1/4H temper. Istrip ingena kwi-stamping press kwi-50–200 m/min, ivelisa iiterminal ze-50,000–200,000 ngeyure nge-progressive die eneemfuno zokunyamezela ezilinganiswa kwii-micrometer. Istrip engaphumeleliyo kuhlolo oluzayo kumzi-mveliso we-elektroniki waseJapan ibuyiselwa kumthengisi ngexabiso lomthengisi, kunye nebango lexesha lokungasebenzi komgca wemveliso we-¥200,000–¥500,000 ngeyure kwi-idle stamping press. Sinikezela nge-cold-rolled stainless steel strip kule marike, kwaye eli nqaku ligubungela iitshekhi ezintlanu ezenziwa yinjineli ye-QA yaseJapan kuyo yonke ikhoyili engenayo. Ukuze ufumane uluhlu lwethu lwemveliso ye-cold rolling, jonga i-iphepha lemveliso yentsimbi engagqwaliyo eqengqelekayo ebandayoUkuze ufumane ulwazi malunga nokukwazi kwenkqubo yokuvelisa imicu echanekileyo, ndwendwela iudidi oluchanekileyo lwe-stainless steel strip.
Ukuqina Okungaguquguqukiyo — Kutheni i-±15 HV Ibalulekile Kwintwasahlobo Edibeneyo
Abavelisi be-elektroniki baseJapan bachaza ubushushu bomcu wentsimbi engagqwaliyo ebandayo ngokwemigangatho emibini esebenza ngaxeshanye: I-JIS G 4313 (imicu yentsimbi engagqwaliyo ebandayo yemithombo) kunye nenkcazo ye-ASTM A240/A480 yeempawu zobushushu ezifanayo. Kwi-1/4H strip kwi-304 stainless steel, uluhlu lobunzima kwi-JIS G 4313 yi-HV 250–310 (ukusasazeka kwamanqaku angama-60). Kwi-1/2H strip kwi-301 stainless steel, uluhlu yi-HV 310–370 (kwakhona namanqaku angama-60). Umgangatho nguuluhlu lobunzima bemveliso yomatshini wokugaya— igubungela utshintsho oluqhelekileyo lwenkqubo yobushushu besithando somlilo esitsaliweyo (±10°C kububanzi bestrip kwisithando somlilo esitsalwayo esiqhubekayo) kunye notshintsho lokunciphisa ubushushu obubandayo (±2% kwipasi yokugqibela kwi-Sendzimir mill). Kodwa kumenzi wesiphelo saseJapan, ukusasazeka kobunzima obungamanqaku angama-60 kubanzi kakhulu kwisiphelo ekufuneka sinike amandla oqhagamshelwano angaguqukiyo kwiistamping ezingama-500,000.
Amandla oqhagamshelwano esiphelo se-spring clip ahambelana namandla okukhupha umcu kwi-radius egobileyo eyenziweyo. Kwi-clip yentsimbi engagqwaliyo eyi-1/2H 301 enobukhulu obuyi-0.3 mm egobileyo kwi-radius yangaphakathi eyi-0.3 mm (umlinganiselo we-R/t = 1.0 - ukugoba okuqinileyo kwi-spring contact), i-angle ye-springback itshintsha nge-0.5° kuyo yonke i-10 HV yokwanda kobunzima be-strip. Utshintsho lwe-60 HV kwi-coil luthetha ukuba i-angle ye-springback iyahluka nge-3° - ukuphakama kwe-clip edibeneyo kuyahluka nge-0.2 mm kwincam yoqhagamshelwano, kwaye amandla okudibana atshintsha ukusuka kwi-8 N echaziweyo ukuya phakathi kwe-6.5 N kunye ne-9.5 N. Umthengi waseJapan uyala nayiphi na ibhetshi apho ubunzima buyahluka ngaphezulu kwe-±15 HV kwi-coil (ifestile enama-30-point). Sihlangabezana nale mfuneko ngokusebenzisa i-rolling mill kwi-controlled reduction per pass kunye ne-sampling hardness kwiindawo ezintlanu (edge left, left quarter, center, right quarter, right edge) kwi-coil nganye kwi-batch, sirekhoda ukuphambuka okuqhelekileyo. Ukuba ukuphambuka okuqhelekileyo kudlula i-8 HV, ikhoyili yehliswa ibe yinkqubo engachanekanga. Uluhlu lwemveliso ye-cold-rolled strip luboniswe kwiiphepha lomcu oqengqelekayo obandayo.
Uburhabaxa Bomphezulu — Ra 0.5 μm ukuze kubekho uzinzo lokumelana nokuxinana
Uburhabaxa bomphezulu we-cold-rolled strip kwicala loqhagamshelwano lwe-terminal bumisela indawo yoqhagamshelwano yokwenyani phakathi kwe-terminal kunye ne-mating pin. I-terminal ephethe i-3 A yesignal current enokumelana nokuqhagamshelana kwe-20 mΩ ifuna indawo yoqhagamshelwano yokwenyani ye-0.01 mm² ubuncinane kwi-nominal contact force (8 N). Ukuba uburhabaxa bomphezulu we-strip yi-Ra 1.0 μm endaweni ye-Ra 0.5 μm, ii-asperities (iincopho) kumphezulu zinde nge-0.5 μm - ukuguquka kweplastiki kwezi asperities phantsi kwamandla okuqhagamshelana kudala indawo yonxibelelwano yokwenyani engaphantsi ngama-30-40%, ityhala ukumelana nokuqhagamshelana ukusuka kwi-20 mΩ ukuya kwi-30-35 mΩ. Kwi-3 A, ukuchithwa kwamandla kwindawo yoqhagamshelwano (I²R = 9 × 0.035 = 0.315 W) kwindlu yokudibanisa evaliweyo ngaphandle komoya kudala ukunyuka kobushushu bendawo ye-15-25°C ngaphezulu kwe-ambient. Kwi-harness ye-injini yeemoto enama-connector angama-60, ubushushu obuqokelelweyo buyawunciphisa ubushushu bentwasahlobo yesiphelo sesiphelo — uxinzelelo lwentsimbi engagqwaliyo ye-1/2H luphumla nge-10–15% kwi-100°C kwiiyure ezingama-3,000, nto leyo enciphisa amandla oqhagamshelwano kwaye yonyusa ukumelana noqhagamshelwano ngakumbi kumjikelo wokusilela okuqinisayo.
Uburhabaxa bomphezulu westrip buxhomekeke kwizinto ezine: ukugqitywa komphezulu westrip yomsebenzi (ukugqitywa komhlaba yiRa 0.1 μm yokudlula kokugqibela), ukucoceka kweoyile eqengqelekayo (inkqubo yesihluzo se-5 μm ethintela amasuntswana aqinileyo ukuba angangeni kumphezulu westrip), uxinzelelo lwestrip ngexesha lokudlula kokugqibela (olugcinwe ngaphakathi kwe-±3% yendawo ebekwe yi-tension reel's closed-loop torque control), kunye nomoya we-annealing furnace (umoya onciphisa i-hydrogen-nitrogen kwi-1,050°C kuma-304 kunye nama-301 grades uthintela imvula ye-carbide kunye ne-oxidation yomphezulu). Silinganisa uburhabaxa bomphezulu kwiindawo ezintathu kububanzi bestrip kwikhoyili nganye sisebenzisa i-contact profilometer ngokwe-ISO 25178. I-Ra eqhelekileyo yi-0.35–0.45 μm kwicala elikhanyayo kunye ne-0.45–0.55 μm kwicala elimatte — umthengi ukhetha icala lomphezulu we-contact. Ukuze ufumane amandla okuvelisa i-hard strip precision, jonga i-iphepha lemveliso yomcu wentsimbi engagqwaliyo echanekileyo.
Ukunyamezela Ubukhulu — ± 0.03 mm Ilawula Ubude Obukhululekileyo beKliphu Egobileyo
Ukunyamezelana kobukhulu kwi-strip ecoliweyo ecoliweyo ngokuchanekile kuchazwe ngokwe-ASTM A480 njenge-±10% ye-nominal gauge yobubanzi ukuya kuthi ga kwi-600 mm. Kubukhulu obuqhelekileyo obuyi-0.30 mm, oku yi-±0.030 mm. Abavelisi be-elektroniki baseJapan nabo bayayinyanzelisa le ntethelelo, kodwa baphinda balinganise umahluko wobukhulu kububanzi be-strip (iprofayili yesithsaba) kunye nobude be-strip (utshintsho lwebhendi ye-gauge). Isithsaba - umahluko wobukhulu phakathi kwe-strip center kunye nomphetho we-strip - akufuneki udlule kwi-0.010 mm kwi-strip ebanzi engama-200 mm kwi-nominal gauge eyi-0.30 mm. Utshintsho lwebhendi ye-gauge - umahluko wobukhulu obuphindaphindeneyo kubude obubangelwa kukungaqhelekanga kweebheringi zangasemva ze-Sendzimir mill - akufuneki udlule kwi-0.005 mm kubude beemitha ezili-10.
Kutheni le nto inqanaba lokuchaneka kwe-spring clip? I-spring clip egxinyiweyo egoba kwi-radius ye-0.5 mm enobukhulu be-strip obuyi-0.30 mm (R/t = 1.67) inobude obukhululekileyo obuyi-4.5 mm. Ukuba ubukhulu be-strip buyi-0.33 mm (umda ophezulu we-±0.03 mm), i-springback geometry iyatshintsha kuba umzuzu we-inertia we-cross-section (I = b × t³ / 12) uyanda ngo-(0.33/0.30)³ = amaxesha ayi-1.33 — i-spring eyenziweyo iqinile ngama-33% xa igoba, kwaye ukuphakama okukhululekileyo kwe-clip kuyanda ngo-0.3 mm ukuya ku-4.8 mm. Amandla okufaka i-pin yokudibana ayatshintsha ukusuka kwinkcazo ye-8 ± 1 N ukuya ku-10 ± 1.5 N — ngaphezulu komda ophezulu womthengi we-9 N. Isiphumo esifanayo sibuyela umva ukuba ubukhulu bukumda ongezantsi we-0.27 mm. Ukunyamezelana kobukhulu be-±0.03 mm kuguqulela ngokuthe ngqo kwi-±0.25 N force variation kwi-spring clip — kwaye ifestile yokwamkela yomthengi yi-±1 N. Sibamba ubukhulu be-±0.02 mm embindini wekhoyili kunye ne-±0.03 mm emaphethelweni ngokusebenzisa ulawulo lwe-automatic gauge oluvaliweyo kwi-pass yokugqibela ye-Sendzimir mill. Ukuze ufumane iimveliso ze-stainless steel strip ngokubanzi, jonga i-iphepha lodidi lwe-strip yentsimbi engagqwaliyo.
I-Edge Burr — I-Punch-and-Die Lifetime Interface
Umcu oqengqelekayo obandayo uqhekeka ukusuka kwikhoyili epheleleyo ukuya kwimigca emincinci (ububanzi obuyi-20-200 mm, kuxhomekeke kububanzi besiphelo kunye noyilo lwedayi yokunyathela) kumgca wokunqumla oneemela ezijikelezayo. Inkqubo yokunqumla idala i-burr kumphetho osikiweyo - umlebe ophakanyisiweyo wezinto ezifudukayo ophuma ngaphezulu komphezulu wedayi nge-0.02-0.15 mm kuxhomekeke ekubeni imela ibukhali kangakanani, indawo yokunqumla (umsantsa phakathi kweemela eziphezulu nezisezantsi, obekwe kwi-5-10% yobukhulu bedayi ukuze inqamleze ngokuchanekileyo), kunye noxinzelelo lwedayi kwi-recoiler yokunqumla. Kwidayi yokunqumla yesiphelo saseJapan esebenza nge-200 strokes ngomzuzu kunye ne-punch-to-die clearance ye-0.020 mm (7% yobukhulu bedayi ye-0.30 mm), i-burr kumphetho wedayi engenayo yinto yokuqala edibana nomphezulu wedayi. Ukuphakama kwe-burr ngaphezu kwe-0.05 mm kuya kubangela i-gall surface ngaphakathi kwe-50,000 strokes - i-galling idala umkrwelo kumhlaba we-die odlulela kwi-terminal nganye elandelayo, ivelisa umqolo ophakanyisiweyo kumphezulu we-terminal othintela i-terminal ukuba ihlale ngokupheleleyo kwi-connector housing.
Silawula ukuphakama kwe-edge burr ngokusebenzisa i-parameter slitting specification ye-three-parameters: i-knife overlap imiselwe kwi-30% yobukhulu be-strip (0.09 mm kwi-0.30 mm strip), i-side clearance yi-8% yobukhulu be-strip (0.024 mm), kwaye i-knife edge radius igcinwa ingaphantsi kwe-0.01 mm — ii-slitting knifes ziyaphinda zigaywe xa i-edge radius idlula i-0.02 mm, okwenzeka emva kweetoni ezingama-30–50 ze-slitting nge-knife set. Ukuphakama kwe-burr kulinganiswa nge-dial indicator kwimitha yokuqala kunye nemitha yokugqibela ye-slit coil nganye. Ukuphakama kwe-burr okudlula i-0.05 mm kususwa nge-deburring station (iseti yeebhloko ze-carbide ezine-spring-loaded ezinqumla i-burr edge nge-0.03 mm ukusuka kwicala ngalinye) kwindawo yokuphuma kwi-slitting line. Umsebenzi wokususa iimbumbulu ubiza i-¥0.30 ngemitha nganye yomgca — kodwa ityala lokulungisa iimbumbulu ze-die yomenzi wesiphelo saseJapan esinezitishi ezintandathu yi-¥150,000–¥300,000, kunye nexesha lokungasebenzi komgca wemveliso. Umsebenzi wokususa iimbumbulu ubandakanyiwe njengomgangatho kuzo zonke ii-odolo ze-strip ezicociweyo ezicociweyo kubathengi be-elektroniki baseJapan, ngaphandle kwentlawulo eyongezelelweyo.
Ukupakishwa kunye nokuHanjiswa — Iimfuneko zeJIT Coil
Abavelisi bee-terminal ze-elektroniki zaseJapan basebenza ngokuhamba kwezinto ngexesha elifanelekileyo (JIT). Ikhoyili engama-500 kg ye-0.30 × 100 mm ecociweyo ebandayo enobude obuphakathi be-strip eyi-2,100 m iyafunyanwa kwaye ibekwe ngqo kwi-reel ye-multi-slide stamping press payoff — akukho ndawo yokugcina ephakathi, akukho hold yokuhlola. Ikhoyili mayingabi namanqaku okusonga adlulayo (i-indentation eyenziwa yi-outer wrap kwi-inner wraps ngexesha lokubuyisela kunye nokuphatha), kuba i-indentation yobunzulu be-0.02 mm kumphezulu we-strip idala umthwalo we-die impact kwi-stamping press — i-punch idibana nokumelana okongezelelweyo kwe-0.02 mm kuloo ndawo, i-press ram tilts, kwaye i-punch tip chipped edge ivelisa i-scrap terminal.
Inkcazelo yokupakisha yeekhoyili ezithunyelwa eJapan ibandakanya: i-spool yentsimbi (ububanzi bangaphakathi be-mandrel buyi-300 mm, ububanzi bangaphandle buyi-450 mm, ii-flanges ezisecaleni buyi-150 mm ububanzi), inxeba le-strip phantsi koxinzelelo oluqhubekayo (50 N nge-10 mm yobubanzi be-strip — 500 N kwi-strip ebanzi ye-100 mm), i-wrap nganye yahlulwe ngephepha le-polyethylene eliyi-0.10 mm ukuthintela ukugoba kwe-wrap-to-wrap, i-coil ivalwe kwibhegi yokuthintela ukufuma nge-vacuum ene-silica gel desiccant (intsimbi engagqwaliyo ayigqwali, kodwa iphepha le-interleaf kufuneka ligcinwe ngaphantsi kwe-10% yomswakama ohambelanayo ukuthintela ii-organic acids zephepha ekungcoliseni umphezulu we-strip ngexesha lokuthuthwa kolwandle), kunye ne-coil epakishwe kwi-crate yokhuni enesiseko se-foam esinciphisa ukungcangcazela. Inani le-weld joint kwi-coil — ikhoyili nganye yenziwe ngokuhlanganisa imicu emininzi ye-coil eyi-5-tonne master coil strips ukusuka ekuqaleni ukuya ekupheleni kumgca wokuqhawula — inqunyelwe kwi-weld joint enye kwi-500 m nganye kwii-odolo zaseJapan, xa kuthelekiswa nomgangatho weshishini we-1 kwi-300 m nganye. Indawo ye-weld joint iphawulwe ngomgca wepeyinti otyheli 30 cm ngaphambi nasemva kwe-joint, kwaye umqhubi we-stamping press uyalelwe ukuba asike aze alahle indawo ye-weld kwisikhokelo sokungena kwi-press.
Uluhlu olupheleleyo lweemveliso esizibonelelayo zezicelo zokunyathela ngokuchanekileyo ludweliswe kwiiphepha lekhathalogu yemveliso.

Imibuzo ebuzwa qho
Ixabiso eliqhelekileyo le-FOB lithini kwi-precision cold-rolled 304 1/4H strip ukuya eJapan?
Ixabiso le-FOB Ningbo le-strip yentsimbi engagqwaliyo ecoliweyo ecoliweyo engu-304, i-temperament eyi-1/4H, ubukhulu obuyi-0.30 mm × ububanzi obuyi-100 mm, kwi-odolo yeetoni ezi-5, yi-$3,200–$3,800 ngetoni. Ixabiso le-strip ye-301 1/2H enobukhulu obufanayo yi-$3,500–$4,200 ngetoni — i-grade ye-301 isebenzisa umxholo ophezulu we-nickel (6.0–8.0% vs. 8.0–10.5% kwi-304, kodwa i-301 inezinga eliphezulu lokuqina komsebenzi elifuna iipasi ezininzi kwi-rolling mill ukuze kufezekiswe i-temperament eyi-1/2H, nto leyo enyusa iindleko zokucubungula). Ixabiso liquka umsebenzi wokususa iimbumbulu, ukupakisha i-polyethylene interleaf, i-crate yomthi, kunye nesatifikethi sovavanyo lomatshini ngokwe-JIS G 4313. Ixabiso alibandakanyi iindleko zokuthumela (ukuthunyelwa ngolwandle ukusuka eNingbo ukuya eYokohama: $120–$180 ngetoni, uthutho lweentsuku ezili-15–20) kunye nerhafu yokusetyenziswa yaseJapan (10%).
Intlawulo eyongezelelweyo ye-nickel iyichaphazela njani ixabiso le-strip kwii-odolo zaseJapan?
Intlawulo eyongezelelweyo ye-nickel kwixabiso le-nickel le-LME isetyenziswa xa umxholo we-nickel wenqanaba udlula umda wesiseko (ngesiqhelo yi-6.0% kwifomula yentlawulo eyongezelelweyo). Kwinqanaba lama-304 kumxholo we-nickel ongu-8.0–10.5%, icandelo lentlawulo eyongezelelweyo libalelwa kwi-18–22% yexabiso lilonke le-strip kwixabiso le-nickel le-LME langoku eliyi-$16,000–$18,000 ngetoni. Kwinqanaba lama-301 kumxholo we-nickel ongu-6.0–8.0%, icandelo lentlawulo eyongezelelweyo liyi-14–17% yexabiso. Intlawulo eyongezelelweyo ibalwa ngokwefomula yentlawulo eyongezelelweyo ye-alloy evunyelwene ngayo kwisivumelwano sokuthenga, edla ngokulungiswa nyanga zonke. Abathengi baseJapan badla ngokucela ikowuteshini yexabiso kunye nentlawulo eyongezelelweyo ye-nickel edweliswe njengento eyahlukileyo yomgca, ngoko ke ixabiso lentsimbi esisiseko kunye nentlawulo eyongezelelweyo zicacile kubalo lwabo lweendleko.
Ingakanani i-odolo encinci yomcu ocoliweyo ocoliweyo olungelelanisiweyo othunyelwa eJapan?
I-MOQ ye-strip yentsimbi engagqwaliyo ecoliweyo ngokucokisekileyo ngebanga ngalinye ngokudibanisa ubukhulu yi-3 tonnes ubunzima be-coil, obumalunga ne-6-8 coil spools kwi-500 kg nganye ngokuxhomekeke kububanzi kunye nobukhulu be-strip. Kumthengi omtsha ongenambali yomgangatho omiselweyo, i-odolo yokuqala yi-5 tonnes ubuncinci ukugubungela isampuli yokuqinisekiswa kwenkqubo (ibhetshi yokuqala ibandakanya uvavanyo olutshabalalisayo kumgca wokuqhawula odla i-20-30 m yezinto ze-coil nganye). Ii-odolo eziphindayo ezivela kubathengi abafanelekileyo zinokuba yi-3 tonnes ubuncinci ngokuthunyelwa ngakunye. Ixesha eliphambili le-odolo yokuqala ziintsuku zokusebenza ezingama-40-45 ukusuka ekugqityweni kwekhontrakthi ye-LJME, kubandakanya umjikelo weentsuku ezili-10 wokuqengqeleka kunye novavanyo ngaphambi kwebhetshi yemveliso. Ii-odolo eziphindayo ziintsuku zokusebenza ezingama-25-30 kuba iiparameter ze-rolling mill sele zimiselwe kwangaphambili kwindibaniselwano yobukhulu bebanga.
Uburhabaxa bomphezulu bulinganiswa njani kwi-strip — ngaba umthengi angakuqinisekisa xa efika?
Uburhabaxa bomphezulu bulinganiswa nge-contact profilometer (uthotho lweTaylor Hobson Surtronic okanye olulinganayo) ene-2 μm radius diamond stylus, ubude bomda obuyi-0.8 mm, kunye nobude bovavanyo lwe-5.6 mm ngokwe-ISO 25178. Umlinganiselo uthathwa kwiindawo ezintathu kububanzi bomtya — 10 mm ukusuka kumda wasekhohlo, umgca ophakathi, kunye ne-10 mm ukusuka kumda wasekunene — kunye nomtya ongashukumiyo kwitafile yokupakisha. Umthengi unokuqinisekisa uburhabaxa ngesixhobo esifanayo xa efika. Umlinganiselo awutshabalalisi — amandla oqhagamshelwano lwe-stylus yi-0.7 mN, engaphawuli umphezulu womtya. Umthengi unokucela isampuli yomtya wokulawula uburhabaxa (ubude obuyi-300 mm ukusuka ekuqaleni nasekupheleni kwekhoyili nganye) ebandakanyiweyo ekuthunyelweni ukuze kuqinisekiswe ilebhu ngokuzimeleyo.
Ingaba ukunyamezelana kobukhulu obuyi-±0.03 mm kuyasebenza kububanzi bomcu opheleleyo?
Ukunyamezelana kobukhulu obuyi-±0.03 mm kusebenza kwi-80% ephakathi yobubanzi bestrip. I-10% yobubanzi kumda ngamnye — ngaphakathi kwe-10 mm yomda osikiweyo — inokunyamezelana okubanzi kwe-±0.05 mm kuba iprofayili yeroli yokusebenza kwe-rolling mill (umqhele weroli ogqunywe kwi-Sendzimir mill work rolls) ibangela ukwanda kobukhulu bendalo kumda westrip. Kwiinkqubo ezininzi zokunyathela i-terminal, ii-terminals zinyatheliswa ukusuka kwi-80% ephakathi yobubanzi bestrip — umda we-10% kwicala ngalinye usetyenziselwa imingxuma yokutya ye-pilot die (imingxuma emincinci ebhobozwe kumda osetyenziswa ngumnwe we-feed ukuze ukhombe umda nge-die). Indawo yomngxuma we-pilot ayifuni ukuchaneka okufanayo kobukhulu kuba ayisiyondawo yokunxibelelana esebenzayo. Abathengi baseJapan bayayamkela le nkcazo yendawo yokunyamezela.
Ngaba ikhoyili inganikwa umsila ongeniswayo ukuze ifakelwe ngokuzenzekelayo kwi-press?
Ewe — senza umsila ongenisiweyo kwangaphambili esiphelweni sekhoyili nganye: isiphelo somcu siyacolwa sibe yi-chamfer engama-30° ngaphezu kobude obuyi-50 mm (sisusa umphetho obukhali wesikwere oza kubamba iirola zesikhokelo sokucinezela), kwaye umsila ugobile kwangaphambili ukuya kububanzi be-spool yereyile yokuhlawula ukuze isiphelo sekhoyili singene kakuhle kwi-straightener yestrip ngaphandle kokugquma okanye ukugoba. Ukulungiswa komsila ongenisiweyo kongeza imizuzu eli-15 ngekhoyili nganye kwisikhululo sethu sokupakisha kwaye kubandakanyiwe kwixabiso eliqhelekileyo lokupakisha. Isiphelo somsila siphawulwe ngomgca wepeyinti oluhlaza ongama-20 cm ukusuka esiphelweni somcu ukuze umqhubi we-press akwazi ukubona isiphelo sekhoyili yokuqala ngokujonga kumgangatho wefektri omnyama.
