1) kumdwebo we-austenite isothermal oguquguqukayo wendawo ejwayelekile, okungukuthi, cishe 500-600 ℃, amanzi esiteji sefilimu ye-steam, izinga lokupholisa alisheshi ngokwanele, ngokuvamile libangela ukupholisa okungalingani kanye nokungapholi okwanele.isivinini forgingskanye nokwakhiwa "kwephuzu elithambile".Kuhlelo lokuguqulwa kwe-martensite, okungukuthi, cishe 300-100℃, amanzi asesiteji sokubilisa, izinga lokupholisa lishesha kakhulu, kulula ukwenza isivinini sokuguqulwa kwe-martensite sishesha kakhulu. futhi ukhiqize ukucindezeleka okukhulu kwangaphakathi, okuholela e-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 lithuthela kumazinga okushisa aphansi. kuholela ekubeni lukhuni kweama-forgings, kodwa kunomphumela omncane esilinganisweni sokupholisa ebangeni lokuguqulwa kwe-martensite.Lapho izinga lokushisa lamanzi likhuphuka lifika ku-60℃, izinga lokupholisa lizokwehla cishe ngo-50%.

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-ke kufanele kuqashelwe ngokukhethekile ukusetshenziswa nokuphathwa. .
Ngokwezici zokupholisa zamanzi, amanzi ngokuvamile H angasetshenziswa ekuqedeni ukupholisa kwekhabhoniizinsimbi zensimbingosayizi 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, ukubhubhisa ulwelwesi olubunjiwe lwe-steam, futhi ungasebenzisa ukushwibeka. i-workpiece ngesikhathi sokucisha (noma yenza i-workpiece iye phezulu naphansi) indlela yokuchitha ulwelwesi lwesitimu, ukwandisa izinga lokupholisa phakathi kuka-500-650 ℃, izimo zokupholisa, gwema ukukhiqiza iphuzu elithambile.
