Kub dov steels rau quenching thiab tempering

quenching thiab tempering, uas yog cov txheej txheem kev kho cua sov uas ib txwm ua rau ntawm qhov kawg ntawm cov khoom tiav, txiav txim siab cov khoom siv tshuab siab.

JINDALAI khoomTxias Ua Haujlwm, Kub Rolled thiab Forged Steels rau quenching thiab Tempering muab cov kev pabcuam customized raws li cov lus qhia tshwj xeeb thiab lwm yam tshwj xeeb kom ua tau raws li txhua tus neeg siv khoom xav tau ntawm cov qib thiab cov ntaub ntawv. Peb lub tuam txhab, nrog nws 10ceg-chaw ua haujlwmhauvTuam Tshojthiab ib xyoos twg muaj peev xwm faib tau txog 200,000 Tons, yog tus khub zoo tshaj plaws los nthuav koj txoj kev lag luam.

 

Dab tsi yog Quench & Tempered Steel?

Tag nrho cov hlau muaj qee qhov carbon, uas ua rau nws nyuaj. 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 hluav taws xob ntawm cov hlau tsis muaj cov pa roj carbon ntau ntxiv.

High-carbon steel muaj qhov sib piv ntawm 0.60 txog 1.00% ntawm cov ntsiab lus carbon piv rau 0.05 txog 0.25% piv ntawm cov hlau me me. Thaum high-carbon steel dhau los ntawm cov txheej txheem quench thiab temper, nws cov khoom siv ua haujlwm ua rau nws hnav-tiv taus thiab ruaj khov.

Cov txheej txheem no tseem nthuav tawm cov khoom lag luam hlau rau ob qho tib si ceev ceev (quenching) thiab rov ua kom sov nrog cov txheej txheem qeeb qeeb (tempering). Ob qhov txheej txheem quenching thiab tempering yog lub luag haujlwm rau kev ntxiv dag zog thiab toughness rau steel.

Txhawm rau cuam tshuam lub hardness thiab lub zog ntawm cov hlau, kev kho cua sov tshwj xeeb, hu ua quenching thiab tempering, tau tsim. Quensching thiab tempering tuaj yeem muab faib ua peb kauj ruam yooj yim:

Austenitizing → cua sov rau saum GSK kab rau hauv thaj av austenite

Quenching → ceev txias hauv qab γγ-αα-transformation

Tempering → rov ua cua sov rau nruab nrab kub nrog qeeb txias
