Inkqubo yokucima kunye nokulungisa umtya wentsimbi engagqwaliyo engama-316L

Ukucima nokulungisa izinto ziinkqubo zonyango lobushushu ezisetyenziselwa ukuphucula iimpawu zoomatshini zezinto, kuquka intsimbi engagqwaliyo efana ne-316L. Ezi nkqubo zihlala zisetyenziselwa ukomeleza ubulukhuni, amandla, kunye nokuqina ngelixa zigcina ukumelana nokugqwala. Nantsi indlela inkqubo yokucima nokulungisa izinto engasetyenziswa ngayo kwi-316L stainless steel strip:

1. Ukuqhoboshela (Ongakukhethayo): Ngaphambi kokuba ucime kwaye ufudumale, ungakhetha ukuqhoboshela intsimbi engagqwaliyo ye-316L ukuze unciphise uxinzelelo lwangaphakathi kwaye uqinisekise ukuba iipropati ezifanayo ziyalingana. Ukuqhoboshela kubandakanya ukufudumeza intsimbi kubushushu obuthile (ngesiqhelo malunga ne-1900°F okanye i-1040°C) uze uyipholise kancinci ngendlela elawulwayo.
2. Ukucima: Fudumeza umcu wentsimbi engagqwaliyo we-316L ukuya kubushushu bawo obuqhelekileyo, ngesiqhelo malunga ne-1850-2050°F (1010-1120°C) kuxhomekeke kulwakhiwo oluthile.
   Bamba intsimbi kolu bushushu ixesha elaneleyo ukuqinisekisa ukuba ifudunyezwa ngokulinganayo.
   Cima intsimbi ngokukhawuleza ngokuyifaka kwisixhobo sokucima, ngokuqhelekileyo ioyile, amanzi, okanye isisombululo sepolymer. Ukukhetha isixhobo sokucima kuxhomekeke kwiimpawu ezifunekayo kunye nobukhulu bomcu.
   Ukucima isinyithi kuyayipholisa ngokukhawuleza, nto leyo ebangela ukuba sitshintshe ukusuka kwi-austenite ukuya kwisigaba esiqinileyo nesibuthathaka ngakumbi, ngokuqhelekileyo i-martensite.
3. Ukufudumala: Emva kokucima, intsimbi iya kuba nzima kakhulu kodwa ibe buthathaka. Ukuze kuphuculwe ukuqina nokunciphisa ubuthathaka, intsimbi iyaqiniswa.
   Ubushushu bokufudumeza bubalulekile kwaye buhlala buphakathi kwama-300-1100°F (150-590°C), kuxhomekeke kwiimpawu ezifunwayo. Ubushushu obuchanekileyo buxhomekeke kwisicelo esithile.
   Bamba intsimbi kubushushu bokufudumeza ixesha elithile, elinokwahluka ngokusekelwe kwiimpawu ozifunayo.
   Inkqubo yokufunxa intsimbi inciphisa ubulukhuni bayo ngelixa iphucula ubulukhuni bayo kunye nokuqina kwayo. Okukhona ubushushu bokufunxa buphezulu, kokukhona intsimbi ithambile kwaye ithambile ngakumbi.
4. Ukupholisa: Emva kokupholisa, vumela umcu wentsimbi engagqwaliyo we-316L uphole ngokwendalo emoyeni okanye ngesantya esilawulwayo ukuya kubushushu begumbi.
5. Uvavanyo kunye noLawulo loMgangatho: Kubalulekile ukwenza uvavanyo loomatshini kunye nolwesinyithi kwi-quinched and tempered strip ukuqinisekisa ukuba iyahlangabezana neemfuno kunye neempawu ezifunwayo. Olu vavanyo lungabandakanya uvavanyo lobunzima, uvavanyo lokuxinana, uvavanyo lwempembelelo, kunye nohlalutyo lwe-microstructure. Iiparameter ezithile zokucima kunye nokulungisa, ezifana namaqondo obushushu kunye nobude, kufuneka zimiselwe ngokusekelwe kwiimpawu ezifunekayo zokusetyenziswa kwaye zinokufuna uvavanyo kunye novavanyo. Ulawulo olufanelekileyo lweenkqubo zokufudumeza, zokubamba, zokucima, kunye nokulungisa lubalulekile ekufezekiseni ibhalansi efunekayo yobunzima, amandla, kunye nokuqina ngelixa kugcinwa ukumelana nokugqwala kwintsimbi engagqwali ye-316L. Ukongeza, amanyathelo okhuseleko kufuneka athathwe xa usebenza ngeenkqubo zobushushu obuphezulu kunye neendlela zokucima.
