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 liyashesha kakhulu, kulula ukwenza isivinini sokuguqulwa kwe-martensite sishesha kakhulu futhi sikhiqize ukucindezeleka okukhulu kwangaphakathi, okuholela ekuguqulweni kwe-forging 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 lidlulela kuzinga lokushisa eliphansi.ama-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 eningi (njengamanzi asanda kuguqulwa), noma amanzi axutshwe nokungcola okungancibiliki, okufana namafutha, insipho, udaka, njll., kuzonciphisa kakhulu amandla awo okupholisa, ngakho-ke ukunakekelwa okukhethekile kufanele kukhokhwe ekusetshenzisweni nasekuphathweni.
Ngokwezici zokupholisa zamanzi, amanzi ngokuvamile H angasetshenziswa ekuqedeni ukupholisa kwekhabhoniizinsimbi zensimbingosayizi omncane wesigaba kanye nokuma okulula.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 ulwelwesi olubushelelezi lwe-steam, ungasebenzisa i-swing workpiece ngesikhathi sokucisha (noma wenze i-workpiece ihamba phezulu naphansi) indlela yokuguqula ulwelwesi olupholile lwe-0 ℃, 5 izimo zokupholisa, gwema ukukhiqiza iphuzu elithambile.
