1, engxenyeni evamile ye-austenitic isothermal transition diagram, okungukuthi, cishe 500-600 ℃, amanzi asesiteji sefilimu ye-steam, futhi isivinini sokupholisa asisheshi ngokwanele, okuvame ukuholela "ephuzwini elithambile" elakhiwe isivinini sokupholisa esingalingani kanye nesivinini esinganele sokupholisa. esiteji, isivinini sokupholisa sishesha kakhulu, kulula ukwenza isivinini sokuguqulwa kwe-martensitic sishesha kakhulu futhi sikhiqize inani elikhulu lokucindezeleka kwangaphakathi, okuholela ekuguqulweni kokukhwabanisa noma ngisho nokuqhekeka.

2, izinga lokushisa lamanzi linethonya elikhulu kumthamo wokupholisa, ngakho-ke liyazwela ekushintsheni kwezinga lokushisa elizungezile. Njengoba izinga lokushisa lamanzi likhula, umthamo wokupholisa wehla kakhulu, futhi izinga lokushisa lezinga eliphezulu lokupholisa lidlulela ekushiseni okuphansi.Lapho izinga lokushisa lamanzi lidlula u-30 ℃, isivinini sokupholisa ebangeni lika-500-600 ℃ siyehla ngokusobala, okuvame ukuholela ekubambeni ukuthi kungabi lukhuni, kodwa kunethonya elincane ejubaneni lokupholisa elipholile ebangeni le-6 lokushisa ℃, lapho izinga lokushisa lamanzi elipholile likhuphuka ku-6 ℃. izinga lizokwehla cishe ngo-50%.

3, lapho amanzi equkethe igesi eyengeziwe (njengamanzi amasha), noma amanzi axutshwe nokungcola okungancibiliki, okufana nowoyela, insipho, udaka, njll., kuzonciphisa kakhulu umthamo wawo wokupholisa, ngakho ukusetshenziswa nokuphathwa kufanele kube ukunakwa okukhethekile.
Ngokwezici zokupholisa amanzi, amanzi H angasetshenziselwa ukucisha nokupholisa ama-carbon steel forgings anesayizi encane yesigaba kanye nesimo esilula.Ukucisha, kufanele futhi uqaphele: gcina izinga lokushisa lamanzi lingaphansi kwama-40 ℃, okungcono kakhulu phakathi kuka-15 kuya ku-30 ​​℃, futhi ugcine ukujikeleza kwamanzi noma uketshezi, ukubhubhisa i-forging surface steam ulwelwesi, noma ungenza ucezu lokusebenza ukuhambisa phansi umshini wokwenza umsebenzi we-swing, noma ungenza ucezu lokusebenza ukuhambisa phansi ukuphazamisa ulwelwesi lwesitimu, ukwandisa izinga lokupholisa phakathi kuka-500-650 ℃, izimo zokupholisa, gwema ukukhiqiza iphuzu elithambile.
