Cov Hlau Kub Rau Quenching thiab Tempering

Kev quenching thiab tempering, uas yog ib qho txheej txheem kho cua sov uas feem ntau ua tiav rau theem kawg ntawm cov khoom, txiav txim siab cov khoom siv kho tshuab siab.

JINDALAI khoom sivCov Hlau Ua Haujlwm Txias, Kub Dov thiab Forged rau Quenching thiab Tempering muab cov kev daws teeb meem raws li cov lus qhia thiab lwm yam kev cai tshwj xeeb kom tau raws li txhua tus neeg siv khoom xav tau ntawm cov qib thiab cov profiles. Peb lub tuam txhab, nrog nws 10ceg-cov chaw ua haujlwmnyob rau hauvTuam Tshojthiab muaj peev xwm faib khoom txhua xyoo txog li 200,000 Tons, yog tus khub zoo meej los nthuav koj txoj kev lag luam.

 

Dab tsi yog Quench & Tempered Steel?

Txhua yam hlau muaj qee cov pa roj carbon, uas ua rau nws tawv dua. Cov pa roj carbon ntau dhau tuaj yeem ua rau cov hlau tsis muaj zog. Cov txheej txheem quench thiab temper yog siv los ua kom cov khoom siv kho tshuab ntawm cov hlau carbon tsis tas ntxiv cov pa roj carbon ntxiv.

Cov hlau uas muaj carbon ntau muaj cov pa roj carbon sib piv li ntawm 0.60 txog 1.00% piv rau cov hlau tsis hnyav uas muaj 0.05 txog 0.25%. Thaum cov hlau uas muaj carbon ntau dhau los ntawm cov txheej txheem quench thiab temper, nws cov khoom siv kho tshuab ua rau nws tiv taus kev hnav thiab ruaj khov dua.

Cov txheej txheem no kuj ua rau cov hlau raug txias sai (quenching) thiab rov ua kom sov dua nrog cov txheej txheem txias qeeb dua (tempering). Ob qho tib si quenching thiab tempering yog lub luag haujlwm rau kev ntxiv lub zog thiab kev tawv rau hlau.

 

Cov kauj ruam ntawm cov txheej txheem For Qkev qhib thiabTkev kub ntxhov

Yuav kom cuam tshuam qhov tawv thiab lub zog ntawm cov hlau, kev kho cua sov tshwj xeeb, hu ua quenching thiab tempering, tau tsim. Quenching thiab tempering tuaj yeem muab faib ua peb kauj ruam yooj yim:

Austenitizing → cua sov kom siab tshaj GSK kab mus rau hauv thaj tsam austenite

Quenching → ceev txias hauv qab γγ-αα-transformation

Tempering → rov ua kom sov rau qhov kub nruab nrab nrog rau kev txias qeeb
