1) kwimephu yenguqu ye-austenite isothermal yendawo eqhelekileyo, oko kukuthi, malunga ne-500-600 ℃, amanzi kwinqanaba lefilimu yomphunga, isantya sokupholisa asikhawulezi ngokwaneleyo, sihlala sibangela ukungalingani.ukwenzaukupholisa kunye nokungonelanga kwesantya sokupholisa kunye nokwakhiwa kwe "soft point".Kwinkqubo yokuguqulwa kwe-martensite, oko kukuthi, malunga ne-300-100 ℃, amanzi akwinqanaba lokubila, izinga lokupholisa likhawuleza kakhulu, kulula ukwenza isantya senguqu ye-martensite ngokukhawuleza kwaye ivelise uxinzelelo oluninzi lwangaphakathi, olukhokelela i-deformation yokubumba kunye nokuqhekeka.
2) Ubushushu bamanzi bunempembelelo enkulu kumthamo wokupholisa, ngoko ke bunovelwano kutshintsho lobushushu be-ambient.Njengoko ubushushu bamanzi bukhuphuka, amandla okupholisa ayancipha ngokukhawuleza, kwaye uluhlu lweqondo lokushisa lomgangatho ophezulu wokupholisa luhamba kwiqondo lokushisa eliphantsi.Xa ubushushu bamanzi bungaphezu kwe-30 ℃, izinga lokupholisa liyehla kakhulu kuluhlu lwe-500-600 ℃, nto leyo ekholisa ukukhokelela ekuqinaforgings, kodwa inempembelelo encinci kwisantya sokupholisa kuluhlu lwenguqu ye-martensite.Xa ubushushu bamanzi bunyuka ukuya kuma-60℃, izinga lokupholisa liyakwehla malunga ne-50%.

3) xa amanzi equlethe igesi eninzi (njengamanzi asanda kutshintshwa), okanye amanzi axutywe nokungcola okunganyibilikiyo, okufana ne-oyile, isepha, udaka, njl. ukuya.
Ngokweempawu zokupholisa zamanzi, amanzi ngokuqhelekileyo H anokusetyenziswa ukucinywa kokupholisa kwentsimbi yekhabhoniforgingskunye nobukhulu becandelo elincinci kunye nemilo elula.Ukucima, kufuneka kwakhona uqaphele: gcina ubushushu bamanzi ngaphantsi kwe-40 ℃, eyona ingcono phakathi kwe-15 ukuya kwi-30 ℃, kwaye ugcine amanzi okanye ukujikeleza kwamanzi, ukutshabalalisaukwenzaUmphezulu wenwebu yomphunga, unokusebenzisa i-workpiece ye-swing ngexesha lokucinywa (okanye wenze i-workpiece ihle inyuka ihle) indlela yokuguqula inwebu yomphunga, yonyusa isantya sokupholisa phakathi kwe-500-650 ℃, iimeko zokupholisa, ukuphepha ukuvelisa indawo ethambileyo.
