Ukucima kunye nonyango olushushu lubhekisela kwindlela yonyango yokushisa kabini yokucima kunye nobushushu obuphezulu, obujolise ekuqinisekiseni ukuba i-workpiece ineempawu ezilungileyo ezibanzi zoomatshini.Ubushushu obuphezulu bubhekisa kubushushu obuphakathi kwe500-650 ℃.Uninzi lwamalungu acinyiweyo kunye nobushushu asebenza phantsi kwemithwalo emikhulu eguqukayo, kwaye athwala iziphumo zoxinzelelo, uxinzelelo, ukugoba, ukugoba okanye ukucheba.Eminye imiphezulu ikwanazo nokungqubana, kufuna ukuxhathisa okuthile, njalo njalo.Ngamafutshane, amalungu asebenza phantsi koxinzelelo olwahlukeneyo oludibeneyo.Ezi ntlobo zamacandelo ubukhulu becala zizinto zolwakhiwo koomatshini kunye neendlela ezahlukeneyo, ezinje ngeeshafti, iinduku zokuqhagamshela, izigxobo, iigiya, njl.Ngokukodwa kumacandelo amakhulu kwimveliso yomatshini onzima, ukucima kunye nonyango lokufudumala lusetyenziswa ngokuqhelekileyo.Ngoko ke, ukucima kunye nonyango lokufudumala ludlala indima ebaluleke kakhulu kunyango lobushushu.Kwiimveliso zoomatshini, iimfuno zokusebenza zamacandelo acinyiweyo kunye nobushushu azifani ngokupheleleyo ngenxa yeemeko zabo ezahlukeneyo zoxinzelelo.Amacandelo ahlukeneyo acinyiweyo kunye nobushushu kufuneka abe neepropathi ezigqibeleleyo zomatshini, ezizezi, indibaniselwano efanelekileyo yamandla aphezulu kunye nokuqina okuphezulu, ukuqinisekisa ukusebenza kakuhle kwexesha elide kwamalungu.
Ukucinywa yinyathelo lokuqala lenkqubo, kwaye ubushushu bokufudumala buxhomekeke ekubunjweni kwentsimbi, ngelixa i-medium quenching ikhethwa ngokusekelwe kubunzima bentsimbi kunye nobukhulu becandelo lentsimbi.Emva kokucima, uxinzelelo lwangaphakathi lwentsimbi luphezulu kwaye luba lukhuni, kwaye ukufudumala kuyimfuneko ukuphelisa uxinzelelo, ukwandisa ukuqina, kunye nokulungelelanisa amandla.I-Tempering yinkqubo ebaluleke kakhulu yokuqhelanisa iipropati ze-mechanical of quenched and tempered steel.Igophe leepropathi zoomatshini zeentsimbi ezahlukeneyo eziguqukayo kunye nobushushu obutshisayo, obukwabizwa ngokuba yigophe lobushushu lentsimbi, linokusetyenziswa njengesiseko sokukhetha ubushushu bobushushu.Ubushushu obuphezulu bobushushu be-alloy ethile ecinyiweyo kunye neentsimbi ezinobushushu, ingqwalasela kufuneka ihlawulwe ekuthinteleni ukwenzeka kohlobo lwesibini lwe-tender brittleness ukuqinisekisa ukusetyenziswa kwentsimbi.[2]
Ukucinywa kunye nonyango olushushu lusetyenziswa ngokubanzi kumacandelo esakhiwo afuna ukusebenza okugqwesileyo okugqwesileyo, ngakumbi abo basebenza phantsi kwemithwalo etshintshanayo, njengeeshafu zemoto, iigiya, iishafti ze-injini yeenqwelomoya, iidiski zokucinezela, njl njl. zidla ngokucinywa kwaye zithotywe phambi kokucinywa komphezulu ukufumana i-sorbate ecolekileyo kunye neyunifomu, enenzuzo kumaleko okuqina komphezulu kwaye inokufikelela kwiimpawu ezilungileyo ezibanzi zoomatshini kumbindi.Amalungu e-nitride atyholwa kunye nonyango olushushu ngaphambi kwe-nitriding, enokuphucula ukusebenza kwentsimbi kunye nokulungiselela isakhiwo se-nitriding.Ukufezekisa ukugudiswa okuphezulu kwesixhobo sokulinganisa ngaphambi kokucima, ukuphelisa uxinzelelo olubangelwa kumatshini olukhuni, ukunciphisa ukucima ukucima, kunye nokwenza ubunzima emva kokucima ukuphakama okuphezulu kunye nokufana, ukucinywa kunye nokunyamezela unyango kunokuqhutywa ngaphambi kokulungiswa ngokuchanekileyo.Kwiintsimbi zesixhobo kunye ne-network carbides okanye iinkozo ezirhabaxa emva kokunyathela, ukucinywa kunye nokufudumala kungasetyenziselwa ukuphelisa inethiwekhi ye-carbide kunye nokucoca iinkozo, ngelixa i-spheroid zing i-carbides ukuphucula ukucwangciswa kunye nokulungiselela i-microstructure yonyango lokugqibela lobushushu.
