Annealing hom ntawmkauv steel yeeb nkab

1. Spheroidizing annealing

Spheroidizing annealing yog tsuas yog siv rau hypereutectoid carbon steel thiab hlau alloy hlau (xws li steel siv rau kev tsim cov cuab yeej txiav, ntsuas cov cuab yeej, thiab pwm).Nws lub hom phiaj tseem ceeb yog txo hardness, txhim kho machinability, thiab npaj rau yav tom ntej hardening.

2. Kev Ntxub Ntxaug Kev Nyuaj Siab

Kev ntxhov siab ntxhov siab annealing tseem hu ua qis kub annealing (los yog kub tempering).Qhov no annealing feem ntau yog siv los tshem tawm cov kev ntxhov siab nyob hauv castings, forgings, welded qhov chaw, kub dov qhov chaw, txias drawn qhov chaw, thiab lwm yam. cov txheej txheem txiav tom ntej.

3, ua kom tiav annealing thiab isothermal annealing

Ua kom tiav annealing tseem hu ua hnyav crystallization annealing, feem ntau hu ua annealing.Qhov no annealing yog tsuas yog siv rau casting, forgings thiab kub dov profiles ntawm ntau yam carbon steels thiab alloy steels nrog.

sub-eutectoid Cheebtsam, thiab qee zaum kuj siv rau vuam cov qauv.Feem ntau siv los ua kev kho cua sov zaum kawg ntawm qee qhov haujlwm tsis hnyav, lossis ua kev kho cua sov ua ntej ntawm qee qhov haujlwm.
