Tempering ntawm Hlau Hlau
Cov hlau uas twb muaj lawm yog reheated rau ib qho kub thiab txias nyob rau hauv ib txoj kev hu ua tempering. Nws lub hom phiaj yog txhawm rau tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm quenching, txo qhov hardness thiab brittleness, thiaj li yuav tau txais cov khoom uas xav tau. Muaj peb hom tempering: kub tempering, nruab nrab kub tempering thiab kub tempering. Tempering yog siv ua ke nrog quenching thiab normalizing.
⑴ Tempering kev kho mob: Txoj kev kho cua sov ntawm qhov kub thiab txias tom qab quenching yog hu ua tempering kho. Kub kub tempering yog hais txog tempering ntawm 500 thiab 650 degree. Tempering tuaj yeem ua rau kev ua tau zoo ntawm cov hlau, cov khoom siv tuaj yeem hloov kho tau zoo, nws lub zog, plasticity thiab toughness yog qhov zoo, muaj cov khoom zoo txhua yam.
(2) Kev laus kev kho mob: txhawm rau txhawm rau tshem tawm cov cuab yeej ntsuas qhov tseeb lossis pwm, qhov chaw nyob rau lub sijhawm siv ntev ntawm qhov loj, cov duab hloov pauv, feem ntau nyob rau hauv qhov kub thiab txias tempering (tsawg kub tempering kub 150-250 degree) ua ntej ua tiav, lub workpiece reheating rau 100-150 degree, tuav 5-20 teev, qhov no yog qhov ruaj khov zoo ntawm precision qhov chaw ua, hu ua aging. Txhawm rau tshem tawm cov kev ntxhov siab uas seem thiab ua kom ruaj khov steel qauv thiab qhov loj me, nws yog ib qho tseem ceeb heev rau cov neeg muaj hnub nyoog steel nyob rau hauv qis kub lossis dynamic load.
