Quenching thiab tempering, uas yog ib txoj kev kho cua sov uas ib txwm nqa tawm ntawm qhov kawg ua tiav theem ntawm daim, txiav txim siab cov khoom siv kho tshuab.
Jindalai movCov khaub thuas txias, kub dov thiab forged cov hlau rau quenching thiab tempering muab cov kev daws teeb meem raws li cov kev xav tau ntawm cov qib kawm thiab cov txheej txheem. Peb lub tuam txhab, nrog nws 10cegchaw ua haujlwmhauvPhiaj suavThiab ib xyoos kev faib tawm muaj peev xwm ua tiav 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 cov pa roj carbon, uas ua rau nws nyuaj. Ntau dhau cov pa roj carbon ntau tuaj yeem tsis muaj zog ntawm cov hlau lub siab. Cov txheej txheem quench thiab temperives yog siv los ua kom cov khoom siv roj carbon hlau yam tsis muaj ntxiv ntawm cov pa roj carbon ntau dua.
High-steel steel muaj 0.60 mus rau 1.00% piv ntawm cov ntsiab lus carbon confitioned rau 0.05% piv ntawm cov hlau me me. Thaum cov roj carbon ntau ntawm cov pa roj carbon ntau, nws cov yam ntxwv ua kom nws muaj ntau cov hnav-tiv taus thiab ruaj khov.
Tus txheej txheem no tseem tau nthuav tawm cov hlau Tshuag rau ob qho tib si txias txias (quenching) thiab rov ua cua sov (tempering). Ob qho tib si quenching thiab tempering cov txheej txheem yog lub luag haujlwm rau kev ntxiv lub zog thiab tawv rau cov hlau.
Txheej Txheem Kauj Ruam For Quenching thiabTkev hloov hoom
Txhawm rau kom ua rau lub hardness thiab lub zog ntawm cov hlau, ib qho kev kho cua sov tshwj xeeb, hu ua quenching thiab tempering, tau tsim. Quensching thiab tempering tuaj yeem muab faib ua peb qib pib:
Austenitizing → cua sov rau saum toj no cov kab gsk mus rau hauv avustenite cheeb tsam
QUching → sai sai txias rau hauv qab γγ--kev hloov pauv
TEmpering → rov ua cua sov rau kev kub khov nrog kub nrog cua txias txias
