1) kumephu yenguquko ye-austenite isothermal yendawo ejwayelekile, okungukuthi, cishe 500-600 ℃, amanzi asesiteji sefilimu ye-steam, isivinini sokupholisa asisheshi ngokwanele, ngokuvamile sibangela ukungalingani.ukuqambaukupholisa kanye nesivinini esinganele sokupholisa kanye nokwakheka "kwephuzu elithambile". Kuhlelo lokuguqulwa kwe-martensite, okungukuthi, cishe ku-300-100 ℃, amanzi asesiteji sokubilisa, izinga lokupholisa lishesha kakhulu, kulula ukwenza isivinini sokuguqulwa kwe-martensite sisheshe kakhulu futhi sikhiqize ukucindezeleka okukhulu kwangaphakathi, okuholela i-deformation yokuqamba ngisho nokuqhekeka.
I-2) Izinga lokushisa lamanzi linethonya elikhulu kumthamo wokupholisa, ngakho-ke liyazwela ekushintsheni kwezinga lokushisa elizungezile. Njengoba izinga lokushisa lamanzi likhuphuka, amandla okupholisa ehla kakhulu, futhi izinga lokushisa lezinga eliphezulu lokupholisa liyahamba liye ezingeni lokushisa eliphansi. Lapho izinga lokushisa lamanzi lidlula ku-30 ​​℃, izinga lokupholisa lehla kakhulu ebangeni lika-500-600 ℃, okuvame ukuholela ekuqineni kwamanzi.ama-forgings, kodwa inomthelela omncane kuzinga lokupholisa ebangeni lokuguqulwa kwe-martensite. Lapho izinga lokushisa lamanzi likhuphuka lifika ku-60℃, izinga lokupholisa lizokwehla cishe ngo-50%.

3) lapho amanzi equkethe igesi ethe xaxa (njengamanzi asanda kuguqulwa), noma amanzi axutshwe nokungcola okungancibiliki, okufana namafutha, insipho, udaka, njll., kuzonciphisa kakhulu umthamo wawo wokupholisa, ngakho ukusetshenziswa nokuphatha kufanele kuqashelwe ngokukhethekile. ku.
Ngokwezici zokupholisa zamanzi, amanzi ngokuvamile H angasetshenziswa ekucimeni kokupholisa kwe-carbon steelama-forgingsngosayizi wesigaba esincane kanye nesimo esilula. Ukucisha, kufanele futhi uqaphele: gcina izinga lokushisa lamanzi lingaphansi kuka-40 ℃, okungcono kakhulu phakathi kuka-15 kuya ku-30 ​​℃, futhi ugcine ukujikeleza kwamanzi noma uketshezi, ukubhubhisaukuqambaUlwelwesi lwesitimu olungaphezulu, lungasebenzisa futhi isiqeshana sokusebenzela ngesikhathi sokucisha (noma senze isiqeshana sokusebenzela siye phezulu naphansi) indlela yokuchitha ulwelwesi lwesitimu, ukwandisa izinga lokupholisa phakathi kuka-500-650 ℃, izimo zokupholisa, gwema ukukhiqiza iphuzu elithambile.
