Xaiv qhov nruab nrab quenching haum yog ib kauj ruam tseem ceeb hauv kev kho cua sov txheej txheem ntawm forgings. Kev xaiv ntawm quenching nruab nrab yog nyob ntawm cov hauv qab no:
Hom khoom: Kev xaiv ntawm quenching nruab nrab txawv rau cov khoom sib txawv. Feem ntau hais lus, carbon steel siv tau dej, roj, los yog polymers li quenching media, thaum hlau alloy siab yuav tsum tau ceev tshaj tawm xws li ntsev da dej los yog roj quenching. Qhov no yog vim cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm qhov hloov pauv kub thiab thermal conductivity energies, xav tau cov cua txias sib txawv.
Qhov loj me thiab cov duab: Cov khoom loj feem ntau yuav tsum tau ua kom txias qeeb kom tsis txhob muaj kev ntxhov siab ntau dhau, uas tuaj yeem ua rau tawg lossis deformation. Yog li ntawd, rau qhov loj, qeeb qeeb tshaj tawm xws li roj tuaj yeem xaiv. Cov khoom me me thiab cov khoom me me yuav xav tau qhov cua txias sai dua kom tau txais qhov xav tau hardness, thiab cov xov xwm txias ceev xws li dej los yog ntsev da dej tuaj yeem xav txog lub sijhawm no.
Yuav tsum muaj hardness: Qhov cua txias ntawm qhov nruab nrab quenching ncaj qha cuam tshuam rau qhov kawg hardness. Qhov kev ua kom txias sai dua tuaj yeem ua kom muaj zog dua, thaum lub zog txias qeeb tuaj yeem ua rau qis qis dua. Yog li ntawd, thaum txiav txim siab qhov yuav tsum tau hardness, nws yog ib qhov tsim nyog los xaiv qhov sib thooj quenching nruab nrab.
Ntau lawm efficiency thiab nqi: txawv quenching media muaj ntau yam efficiency thiab nqi. Piv txwv li, dej raws li qhov nruab nrab quenching muaj qhov cua txias ceev, tab sis qee zaum nws yuav ua rau deformation lossis tawg ntawm cov khoom. Roj raws li qhov nruab nrab quenching muaj qhov ua kom txias qeeb, tab sis tuaj yeem muab cov khoom zoo dua qub thiab txo qis deformation rau qhov chaw. Media xws li ntsev da dej thiab roj quenching muaj ntau dua efficiency tab sis tus nqi siab dua. Yog li ntawd, thaum xaiv quenching media, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog kev tsim khoom thiab cov nqi tsim nyog.
Hauv cov ntsiab lus, xaiv qhov nruab nrab quenching tsim nyog yuav tsum tau xav txog ntau yam xws li cov khoom siv, qhov loj me thiab cov duab, xav tau hardness, ntau lawm efficiency, thiab nqi. Hauv kev siv cov tswv yim, feem ntau yuav tsum tau ua cov kev sim thiab kev ua kom zoo kom pom qhov tsim nyog tshaj plaws quenching nruab nrab rau cov ntawv thov tshwj xeeb.
