Lub sijhawm tua hluav taws feem ntau luv, tab sis qhov kub thiab txias yuav tsum tau tswj kom meej.
Lub sijhawm ua kom sov: Nyob ntawm cov ntaub ntawv sib txawv thiab cov txheej txheem xav tau, lub sijhawm ua kom sov feem ntau yog li ntawm 2 thiab 3 feeb. Piv txwv li, thaum siv cov hlau tsis muaj carbon tsawg los tsim cov saw hlau, qhov kub ntawm kev ua kom sov yog 870-890 ℃ thiab lub sijhawm ua kom sov yog 2-3 feeb.
Lub sijhawm txias: Lub sijhawm txias ntawm kev quenching yog luv luv thiab feem ntau ua tiav hauv ob peb feeb. Kev tswj hwm qhov nrawm txias yog qhov tseem ceeb vim nws cuam tshuam ncaj qha rau qhov nyuaj thiab kev ntxhov siab sab hauv ntawm cov saw hlau.
2. Kev ua kom sov
Kev kho kom sov yog kauj ruam thib ob ntawm kev kho tom qab cua sov ntawm cov saw hlau. Nws lub hom phiaj yog kom txo qhov kev ntxhov siab sab hauv tom qab quenching los ntawm kev cua sov qis thaum tswj hwm qee qhov nyuaj thiab tawv. Lub sijhawm tempering feem ntau ntev dua li lub sijhawm quenching.
Kev Ua Ntej Kub: Qhov kub ntawm kev ua ntej kub feem ntau yog li ntawm 130 ℃, thiab lub sijhawm tuav yog li 2.5 txog 3.5 teev. Cov kauj ruam no pab txhawb kom ruaj khov cov qauv sab hauv ntawm cov saw hlau.
Kev kub hnyiab thib ob: Qhov kub ntawm kev kub hnyiab thib ob feem ntau yog li ntawm 250 ℃, thiab lub sijhawm tuav yog 4 txog 5 teev. Kev kub hnyiab thib ob tuaj yeem ua kom zoo dua cov khoom siv kho tshuab ntawm cov saw hlau thiab ua kom nws ruaj khov hauv kev siv mus sij hawm ntev.

Cov yam tseem ceeb uas cuam tshuam rau lub sijhawm kho tom qab cua sov ntawm cov saw hlau

1. Cov khoom siv sib xyaw

Cov khoom siv sib xyaw ua ke ntawm cov saw hlau muaj feem cuam tshuam loj heev rau nws lub sijhawm kho tom qab cua sov thiab cov txheej txheem. Piv txwv li, qhov kub thiab sijhawm quenching ntawm cov hlau qis-carbon tsawg-alloy txawv ntawm cov hlau carbon ib txwm. Cov khoom sib xyaw ua ke sib txawv xav tau kev hloov kho qhov kub thiab txias, lub sijhawm tuav thiab tus nqi txias kom ntseeg tau tias muaj cov khoom siv kho tshuab zoo tshaj plaws.

2. Qhov loj ntawm cov saw hlau

Qhov loj ntawm cov saw hlau kuj cuam tshuam rau lub sijhawm kho tom qab cua sov. Cov saw hlau loj dua xav tau lub sijhawm ua kom sov thiab txias ntev dua kom ntseeg tau tias muaj kev faib tawm cua sov sib npaug thiab kev hloov pauv hauv cov qauv sab hauv.

3. Cov kev cai ntawm kev ua kom raug

Cov ntawv thov sib txawv muaj cov kev cai sib txawv rau qhov tseeb thiab kev ua tau zoo ntawm cov saw hlau. Piv txwv li, cov saw hlau uas muaj qhov tseeb siab thiab lub neej ntev xav tau cov txheej txheem kho cua sov ntau dua thiab lub sijhawm ua haujlwm ntev dua. Cov txheej txheem kho cua sov ntawm cov saw hlau no suav nrog ntau kauj ruam xws li preheating, carburizing thiab quenching, txias, ntxuav, pre-tempering thiab secondary tempering, thiab lub sijhawm thiab cov kev cai ntawm txhua kauj ruam yuav tsum tau tswj hwm kom meej.
