Sand casting steel peev casting yog hais txog kev ua tus qauv fusible nrog cov ntaub ntawv fusible, txheej ob peb txheej tshwj xeeb refractory coatings rau nws, ziab thiab hardening los tsim ib lub plhaub, thiab tom qab ntawd siv chav lossis dej kub los tsim pwm.Melt tawm cov qauv hauv lub plhaub, tom qab ntawd muab lub plhaub tso rau hauv lub thawv xuab zeb, sau ib puag ncig nrog cov xuab zeb qhuav, muab cov pwm tso rau hauv lub qhov cub ci rau qhov kub kub roasting, thiab ncuav cov hlau molten rau hauv cov pwm los yog lub plhaub tom qab roasting. Thiab tau txais castings.
Cov txheej txheem yog kom sov ntau yam castings mus rau qhov kub ntawm 860-900 ℃, khaws cov qub matrix tag nrho cov austenitized, ces txias hauv cov roj los yog molten ntsev kom tiav quenching, thiab ces kub, kub, kub thiab kub ntawm 250-350 ℃, thiab tus thawj matrix yog hloov mus rau hauv Tempered martensite thiab khaws cia austenite qauv, tus kheej kheej kheej graphite duab tseem tsis hloov.Ductile castings yuav tsum tau hardness ntau dua li bearings, thiab idler log sib dhos yog feem ntau quenched thiab tempered ntawm tsawg kub.
Cov kev kho castings muaj siab hardness thiab tej yam toughness, Liaoning cam khwb cia hlau tuav lub lubricating zog ntawm graphite, thiab hnav kuj yog ntxiv txhim kho.Cov khoom tau txais los ntawm peev casting yog complex, ze rau cov duab ntawm qhov chaw, thiab yuav siv tau ncaj qha yam tsis muaj los yog nrog me me ua.Nws tsis yog tsuas yog tsim rau casting ntawm ntau hom thiab alloys, tab sis kuj tsim castings nrog siab dua qhov tseeb thiab nto zoo tshaj li lwm yam casting txoj kev, thiab txawm complex, kub resistant thiab nyuaj rau txheej txheem castings uas yog nyuaj rau cam khwb cia los ntawm lwm yam casting. txoj kev.Yuav raug nrum los ntawm peev casting.
