Quenching yog ib txoj hauv kev tseem ceeb hauv kev kho cua sov hlau, uas hloov lub cev thiab lub zog ntawm cov khoom siv los ntawm kev ua kom txias sai.Thaum lub sij hawm quenching txheej txheem, lub workpiece undergoes theem xws li high-kub cua sov, rwb thaiv tsev, thiab ceev ceev txias.Thaum lub workpiece txias sai heev los ntawm qhov kub thiab txias, vim qhov kev txwv ntawm cov khoom theem hloov pauv, lub microstructure ntawm workpiece hloov, tsim cov qauv tshiab thiab kev ntxhov siab hauv cov khoom.
Tom qab quenching, lub workpiece feem ntau yog nyob rau hauv ib tug kub lub xeev thiab tseem tsis tau tag nrho txias rau chav tsev kub.Nyob rau lub sijhawm no, vim qhov sib txawv ntawm qhov kub thiab txias ntawm qhov chaw ntawm qhov chaw ua haujlwm thiab ib puag ncig, lub workpiece yuav txuas ntxiv hloov cov cua sov ntawm qhov chaw mus rau sab hauv.Cov txheej txheem hloov hluav taws xob no tuaj yeem ua rau qhov ntsuas kub hauv zos hauv qhov chaw ua haujlwm, txhais tau hais tias qhov kub ntawm qhov sib txawv hauv qhov chaw ua haujlwm tsis zoo ib yam.
Vim yog qhov seem ntawm kev ntxhov siab thiab cov qauv kev hloov pauv tau tsim thaum lub sij hawm quenching, lub zog thiab hardness ntawm lub workpiece yuav zoo dua.Txawm li cas los xij, cov kev hloov no tseem tuaj yeem ua rau cov khoom ua haujlwm brittleness thiab tuaj yeem ua rau qee qhov kev tsis xws luag xws li tawg lossis deformation.Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua kev kho tempering ntawm lub workpiece kom tshem tawm cov kev ntxhov siab uas seem thiab ua tiav qhov kev ua tau zoo.
Tempering yog txheej txheem ntawm cua sov lub workpiece mus rau ib tug tej yam kub thiab txias nws, nrog rau lub hom phiaj ntawm kev txhim kho cov microstructure thiab cov khoom tsim tom qab quenching.Tempering kub feem ntau qis dua qhov kub thiab txias, thiab qhov kub thiab txias tuaj yeem raug xaiv raws li cov yam ntxwv thiab cov kev xav tau ntawm cov khoom.Feem ntau, qhov siab dua qhov kub thiab txias, qhov qis dua qhov hardness thiab lub zog ntawm lub workpiece, thaum lub toughness thiab plasticity nce.
Txawm li cas los xij, yog tias lub tshuab ua haujlwm tsis tau txias rau hauv chav tsev kub, piv txwv li, tseem nyob ntawm qhov kub thiab txias, kev kho tempering tsis tuaj yeem ua tau.Qhov no yog vim hais tias tempering yuav tsum tau cua sov lub workpiece mus rau ib tug tej yam kub thiab tuav nws rau ib lub sij hawm ntawm lub sij hawm kom ua tiav cov kev xav tau.Yog tias lub workpiece twb nyob rau ntawm qhov kub thiab txias, cov txheej txheem cua sov thiab rwb thaiv tsev yuav ua tsis tau, uas yuav ua rau tempering nyhuv tsis tau raws li qhov kev cia siab.
Yog li ntawd, ua ntej kev kho tempering, nws yog ib qho tsim nyog los xyuas kom meej tias lub workpiece tau txias tag rau hauv chav tsev kub los yog ze rau chav tsev kub.Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tau zoo tempering kev kho mob los kho qhov kev ua haujlwm ntawm lub workpiece thiab tshem tawm qhov tsis xws luag thiab kev ntxhov siab tsim tawm thaum lub sijhawm quenching.
Nyob rau hauv luv luv, yog hais tias lub quenched workpiece tsis txias rau chav tsev kub, nws yuav tsis tau mus rau tempering kev kho mob.Tempering yuav tsum tau cua sov lub workpiece mus rau ib tug tej yam kub thiab tswj nws rau ib lub sij hawm ntawm lub sij hawm, thiab yog hais tias lub workpiece twb nyob rau ntawm ib tug kub siab dua, lub tempering txheej txheem yuav tsis tau zoo.Yog li ntawd, nws yog ib qho tseem ceeb heev los xyuas kom meej tias lub workpiece yog tag nrho txias rau chav tsev kub ua ntej tempering thaum lub sij hawm kho cua sov txheej txheem kom paub meej tias lub workpiece yuav ua tau raws li qhov yuav tsum tau ua thiab zoo.
