Cov txheej txheem annealing ntawmforgingstuaj yeem muab faib ua tiav annealing, tsis tiav annealing, spheroidizing annealing, diffusion annealing (homogenizing annealing), isothermal annealing, de-kev nyuaj siab annealing thiab recrystallization annealing raws li muaj pes tsawg leeg, yuav tsum tau thiab lub hom phiaj ntawm annealing.
(1) ua tiav cov txheej txheem annealing
① Daim ntawv thov Scope:nruab nrab carbon steel, nruab nrab carbon siab alloy steel castings, nruab nrab carbon tsawg alloy steel castings, vuam qhov chaw,forgings, dov qhov chaw thiab lwm yam kev kho mob annealing.
② Nthuav dav B
A. Txhim kho coarse grain qauv, refine grain loj, tshem tawm Widmannian qauv thiab banded qauv;
B. Txo hardness thiab txhim kho kev ua haujlwm txiav;
C. Tshem tawm kev ntxhov siab sab hauv;
D. Kev kho cua sov kawg rau qhov tsis tseem ceeb.

(2) Cov txheej txheem annealing tsis tiav
① Daim ntawv thov Scope:annealing kev kho mob ntawm hypoeutecoid steel, carbon structural steel, carbon cable cuab yeej steel, tsis tshua muaj hlau structural steel, tsis tshua muaj hlau cuab yeej steel thiab hyeutectoid steel forgings, kub dov qhov chaw, thiab lwm yam.
② Lub hom phiaj ntawm kev ua tsis tiav annealing:tshem tawm cov kev ntxhov siab sab hauv ntawm forging dov, txo hardness thiab txhim kho toughness.

(3) spheroidizing annealing
① Daim ntawv thov Scope:
A. Kev npaj thiab kev kho cua sov ntawm cov kabmob thiab cov cuab yeej steels thiab lwm yam hypereutectoid steels;
B. Txias deformation forging annealing kev kho mob ntawm nruab nrab thiab qis carbon steels thiab nruab nrab thiab tsawg carbon alloy steels.
② Lub hom phiaj ntawm spheroidizing annealing:
A. Rauforgingsuas yuav tsum tau txiav, txo hardness thiab txhim kho kev ua tau zoo;
B. Txhawm rau txhim kho plasticity ntawm txias-deformed workpiece tsis txiav;
C. Spherical carbide los tiv thaiv overheating tom qab quenching thiab npaj rau qhov kawg kub faus;
D. Tshem tawm kev ntxhov siab sab hauv.
(4) Isothermal annealing
① Daim ntawv thov ntawm isothermal annealing:tuag steel, alloy steel forgings, stamping qhov chaw.
②Qhov zoo ntawm isothermal annealing:nws tuaj yeem txo lub voj voog annealing thiab txo cov nqi tsim khoom.
