Isitshixo sokuphuhlisa iiinkcukacha zokupholisa zefogiemvaukwenzakukukhetha umlinganiselo wokupholisa ofanelekileyo ukuphepha iziphene zokupholisa ezikhankanywe ngasentla. Ngokuqhelekileyo, i-post-forging yokupholisa inkcazo inqunywe ngokwemichiza yekhemikhali, iimpawu ze-microstructure, imeko ye-raw material kunye nobukhulu becandelo lezinto ezimbi, ngokubhekiselele kwidatha efanelekileyo.
Ngokubanzi, okukhona kulula ukubunjwa kweekhemikhali ezingenanto, ngokukhawuleza isantya sokupholisa emva kokoukwenza, kwaye icotha ngenye indlela. Kwintsimbi yekhabhoni kunye nentsimbi ephantsi ye-alloyforgings, ukupholisa umoya kunokwamkelwa emva kokoukwenza. Kwaye ukubunjwa kwe-alloy eyinkimbinkimbi yensimbi ephezulu ye-alloyforgingsokanye forgings eliphezulu ukuqina, emva forging kufuneka kuthathwe ukupholisa emhadini okanye eziko lokupholisa.
Ukuba isixhobo sentsimbi yekhabhoni, isixhobo sensimbi yentsimbi kunye nentsimbi ethwele intsimbi enomxholo ophezulu wekhabhoni zipholiswa kancinci emvaukwenza, i-network carbide iya kudlula kumda wokudla okuziinkozo, okuya kuchaphazela kakhulu ukusebenza kwenkonzo ye-forgings. Ke ngoko, olu hlobo lokubunjwa lupholiswe ukuya kwi-700 ℃ ngokupholisa umoya, ukuqhushumba okanye ukutshiza ngokukhawuleza emva kokubunjwa, kwaye emva kokoforgingszibekwe emingxunyeni okanye ezikweni ukuze ziphole kancinane.

Kwinsimbi ye-austenitic, insimbi ye-ferrite kunye nezinye iintsimbi ngaphandle kokuguqulwa kwesigaba, ukupholisa ngokukhawuleza kunokwamkelwa ngenxa yokuba akukho kuguqulwa kwesigaba kwinkqubo yokupholisa emva kokupholisa.ukwenza. Ukongeza, ukupholisa okukhawulezileyo kuyafuneka ukuze ufumane ubume besigaba esinye kunye nokuthintela ukupholisa okucothayo kwentsimbi ye-ferrite kwi-475 ℃. Ke ngoko, olu hlobo lokubumba lunokupholiswa emoyeni emva kokoukwenza.
Kwiintsimbi ezipholileyo emoyeni, ezifana nentsimbi ye-bainitic, intsimbi ye-martensitic, isinyithi esinesantya esiphezulu, intsimbi ephezulu ye-alloy, njl. Ngenxa yokupholisa umoya, i-bainite kunye nokuguqulwa kwe-martensite kunokwenzeka, okuya kubangela uxinzelelo olukhulu lwe-microstructure kwaye kulula ukuvelisa iintanda zokupholisa. . Ke ngoko, olu hlobo lokubumba kufuneka lupholiswe kancinci emva kokoukwenza.
Kwintsimbi yentsimbi emhlophe, njengentsimbi ye-chrome-nickel, ukuze kuthintelwe indawo emhlophe kwinkqubo yokupholisa, ukupholisa iziko kufuneka kuqhutywe ngokwemigaqo ethile yokupholisa.
Forgingsezenziwe ngentsimbi zinesantya sokupholisa ngokukhawuleza emvaukwenza, ngelixa ezo zenziwe ngentsimbi ye-ingot zinezinga lokupholisa elicothayo. Ukongeza, i-forgings enobungakanani becandelo elikhulu kufuneka ipholiswe ngokukhawuleza emva kokukhwabanisa ngenxa yoxinzelelo olukhulu lobushushu bokupholisa, ngelixa i-forgings enobungakanani becandelo elincinci inokupholiswa ngokukhawuleza emva kokukhwabanisa.
