Tempering yog txheej txheem kev kho cua sov uas heats quenchedhlau alloyhlau cov khoom los yog qhov chaw rau ib tug tej yam kub thiab txias, tuav lawv rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias lawv nyob rau hauv ib txoj kev.Tempering yog ib qho kev ua haujlwm tam sim ntawd tom qab quenching, thiab nws feem ntau yog cov khoom ua haujlwm uas tau txais kev kho cua sov.Cov txheej txheem kawg, yog li cov txheej txheem ua ke ntawm quenching thiab tempering yog hu ua kev kho zaum kawg.
2. Lub hom phiaj tseem ceeb ntawm quenching thiab tempering yog:
1) Txo cov kev ntxhov siab sab hauv thiab brittleness.Quenched qhov chaw muaj kev ntxhov siab zoo thiab brittleness.Yog hais tias lawv tsis tempered nyob rau hauv lub sij hawm, lawv yuav feem ntau deform los yog txawm tawg.
2) Kho cov khoom siv kho tshuab ntawm lub workpiece.Tom qab quenching, lub workpiece muaj siab hardness thiab brittleness.Txhawm rau ua kom tau raws li qhov sib txawv ntawm kev ua haujlwm ntawm ntau yam haujlwm, qhov hardness, lub zog, plasticity thiab toughness tuaj yeem hloov kho los ntawm tempering.
3) ruaj khov workpiece loj.Tempering tuaj yeem txhim kho cov qauv metallographic kom ntseeg tau tias nws yuav tsis deform thaum siv tom ntej.
4) Txhim kho qhov kev ua tau zoo ntawm qee cov hlau alloy.
Cov txheej txheem quenching thiab tempering plays lub luag haujlwm zoo hauv kev txhim kho qhov zoo ntawmcemented carbide.Txhua yam tam sim notungsten carbide txias taub hau pwmyuav quenched thiab tempered tom qab sintering.
