Forgings ntawm annealing txheej txheem raws li muaj pes tsawg leeg yuav tsum tau ntawm txawv annealing lub hom phiaj, yuav muab faib ua tag nrho annealing tsis tiav homogenizing annealing spheroidizing annealing (homogenizing annealing) rau kev nyuaj siab annealing thiab isothermal annealing recrystallization annealing Scope ntawm daim ntawv thov:
a.B txhim kho cov txheej txheem tuab, ua kom zoo dua cov nplej, tshem tawm cov qauv widmanstatten thiab banded qauv;
B. Txo hardness thiab txhim kho kev ua haujlwm txiav;
C. Tshem tawm kev ntxhov siab sab hauv;
D. Nws tuaj yeem siv los ua kev kho cua sov zaum kawg rau qhov tsis tseem ceeb.
(2) Cov txheej txheem annealing tsis tiav
Daim ntawv thov: subeutectoid steel, carbon structural steel, carbon cable cuab yeej steel, tsis tshua muaj alloy structural steel, tsis tshua muaj alloy cuab yeej steel thiab hypereutectoid steel forging, kub dov daim thiab thiaj li nyob rau annealing kev kho mob.
Lub hom phiaj annealing tsis tiav: tshem tawm cov kev ntxhov siab sab hauv ntawm forging thiab dov, txo hardness, txhim kho toughness.
(3) Spheroidizing annealing
Scope ntawm kev siv:
A. Kev npaj kho cua sov ntawm hypereutectoid steel xws li cov kabmob steel thiab cov cuab yeej steel;
B. Txias deformed forging annealing kev kho mob ntawm nruab nrab thiab qis carbon steels thiab nruab nrab thiab qis carbon alloy steels.
Lub hom phiaj ntawm spheroidizing annealing
A. Rau forgings xav tau kev txiav, txo hardness thiab txhim kho kev ua haujlwm;
B. Rau qhov txias deformation workpiece yam tsis tau txiav, txhim kho plasticity ntawm txias deformation workpiece;
C. Spheroidized carbide los tiv thaiv overheating tom qab quenching thiab npaj rau faus rau hauv qhov chaw kub kawg;
[D] Tshem tawm kev ntxhov siab sab hauv.
(4) Isothermal annealing
Isothermal annealing daim ntawv thov: tuag steel, alloy steel forging, stamping qhov chaw.
Qhov zoo ntawm isothermal annealing: tuaj yeem txo lub voj voog annealing, txo cov nqi tsim khoom.
