High zaus quenching tshuab manufacturers luv luv piav qhia txog cov txheej txheem annealing ntawm steel

1. Ua kom tiav

Txheej txheem: Cua sov saum Ac3 mus rau 30-50 ° C → kev txuag hluav taws xob → txias kom qis dua 500 degrees nrog rau lub cub tawg → cua txias rau chav tsev kub.

Lub hom phiaj: txhawm rau txhim kho cov nplej, cov qauv zoo ib yam, txhim kho plasticity thiab toughness, tshem tawm cov kev ntxhov siab sab hauv, thiab pab txhawb kev ua haujlwm.

2. Isothermal annealing

Txheej txheem: cua sov saum Ac3 → Thaum tshav kub kub preservation → ceev ceev txias rau pearlite transformation kub → isothermal nyob → transformation rau P → cua txias;

Purpose: Ib. Tab sis lub sij hawm luv luv, yooj yim los tswj, thiab deoxidation thiab decarburization yog me me. (Suitable for alloy steel thiab loj carbon steel qhov chaw nrog kuj ruaj khov supercooled A).

3. Spheroidizing annealing

Tswv yim: Nws yog cov txheej txheem ntawm spheroidizing cementite hauv hlau.
