1, Kev ntxhov siab annealing
Kev ntxhov siab nyem annealing, tseem hu ua low-temperature annealing (los yog tempering), uas yog tsuas yog siv los tshem tawm annealing casting, forging, vuam, kub dov, txias-drawn pieces residual stress thiab lwm yam. Yog tias tsis tshem tawm cov kev ntxhov siab no yuav ua rau cov hlau tom qab qee lub sijhawm, lossis deformation lossis tawg hauv cov txheej txheem machining tom ntej.

2, Lub pob annealing
Pob annealing feem ntau yog siv HYPEREUTECTOID cov pa roj carbon steel thiab cov cuab yeej hlau hlau (xws li kev tsim cov cuab yeej txiav, ntsuas cov cuab yeej, pwm siv hlau). Nws lub hom phiaj tseem ceeb yog txo qhov hardness los txhim kho machinability, thiab hardened los npaj rau yav tom ntej.

3, Ua kom tiav annealing thiab isothermal annealing
Kuj hu ua tag nrho annealing recrystallization annealing, feem ntau hu ua annealing, lub annealing yog tsuas yog siv rau sub-eutectoid muaj pes tsawg leeg ntawm ntau yam carbon thiab alloy steel casting, forging thiab kub dov profiles, tej zaum rau welded lug. Feem ntau feem ntau raws li qee qhov hnyav ntawm lub workpiece tsis yog qhov kawg kev kho cua sov, lossis raws li kev kho cua sov ua ntej ntawm qee qhov workpiece.
