25CrMo4 Khoom Khoom
Khoom Description
25crmo4 cov khoom sib npaug yog 1.7218/4130/SCM430/30CrMo.
25CrMo4 steel tuaj yeem tau txais lub zog zoo thiab tawv tom qab kev kho cua sov kom zoo. Cov txheej txheem ntawm kev kho cua sov muaj xws li normalizing, quenching thiab tempering cov kauj ruam kom ua tau raws li qhov xav tau cov khoom siv kho tshuab. Thaum lub sij hawm normalizing, 25crmo4 cov khoom yog rhuab mus rau qhov zoo kub thiab ces txias nyob rau hauv cov huab cua kom lub zog ntawm cov hlau. Thaum lub sij hawm quenching txheej txheem, 25CrMo4 forged steel bar yog txias sai heev kom tau ib tug ntau dua hardness. Cov txheej txheem tempering yog rov ua kom cov hlau quenched kom txo nws cov brittleness.

25CrMo4 Steel Thaum tshav kub kub kho
Kev kho cua sov ntawm 25CrMo4 steel yog qhov tseem ceeb rau nws qhov kev ua tau zoo kawg. Los ntawm kev kho cua sov kom tsim nyog, hardness thiab hnav tsis kam ntawm 25CrMo4 cov khoom tuaj yeem txhim kho tau zoo. Cov kev kho cua sov uas muaj xws li:
- quenching: Cua sov steel rau ib qho kub thiab txias sai kom tau txais cov qauv martensitic, yog li txhim kho hardness.
- Tempering: Kev kho tempering tom ntej tuaj yeem tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm quenching, txhim kho lub toughness thiab plasticity ntawm cov hlau.
Muab daim ntawv
Sichuan Huitai Tshwj Xeeb Hlau Co., Ltd muab 25CrMo4 steel nyob rau hauv ntau hom kom tau raws li qhov xav tau ntawm kev lag luam sib txawv. Cov ntaub ntawv nrov ntawm kev muab khoom yog raws li hauv qab no:
- Kub dov (HR): Hlau yog dov ntawm qhov kub thiab txias thiab muaj cov khoom siv zoo.
- Annealing (A): Tom qab kev kho cua sov kom tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho plasticity.
- Kev kos duab txias (C): Txhim kho lub zog thiab hardness los ntawm kev ua haujlwm txias.
- Foring: Diamter loj dua 180mm, peb tuaj yeem siv cov txheej txheem forging los tsim forged tuav rau koj.
Kev Xa Khoom
- Normalization (N): Optimizing grain qauv los ntawm kev kho cua sov los txhim kho cov khoom toughness.
- Tempering (T): Ua tiav qhov tshwj xeeb ntawm hardness thiab lub zog los ntawm kev kho cua sov.
- Quenching thiab tempering (QT): Ua kom tawv tawv los ntawm quenching, ua raws li tempering los txhim kho toughness.
25CrMo4 cov ntaub ntawv tau siv dav hauv ntau qhov kev lag luam vim nws qhov kev ua tau zoo heev:
