Lub sij hawm hardened steel feem ntau yog siv rau nruab nrab lossis siab carbon steel uas tau muab kev kho cua sov thiab ces quenching ua raws li tempering. Lub quenching tshwm sim nyob rau hauv lub tsim ntawm metastable martensite, cov feem ntawm uas yog txo mus rau qhov xav tau npaum li cas thaum tempering.

Yuav ua li cas quenching muaj rau cov pa roj carbon siab?

Txias txawm tias nrawm dua-piv txwv li, los ntawm kev tua cov hlau ntawm li 1, 000 ° C ib feeb-ua rau ua tiav kev nyuaj siab ntawm carbide tsim thiab yuam cov ferrite undercooled los tuav cov nyiaj ntau. carbon atoms nyob rau hauv kev daws uas nws yeej tsis muaj chaw. Qhov no generates ib tug tshiab microstructure, martensite.

Cov pa roj carbon siab feem ntau yog dab tsi?

Nruab nrab thiab siab carbon steels feem ntau yog quenched hauv polymer thiab roj txhawm rau kom tsis txhob tawg thiab tawg; Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau ua pov thawj tias nws muaj peev xwm txo qis kev tawg siv dej los ua qhov txias ntawm cov hlau no los ntawm kev txhawb nqa cov cua txias heev.

Koj puas tuaj yeem ua cov hlau nruab nrab cov pa roj carbon monoxide?

Cov hlau me me thiab nruab nrab carbon steel tsis muaj cov pa roj carbon txaus los hloov lawv cov qauv crystalline thiab yog li tsis tuaj yeem tawv thiab tempered.

Yuav ua li cas thaum quenching?

Hauv cov ntaub ntawv tshawb fawb, quenching yog nrawm nrawm ntawm cov khoom ua haujlwm hauv dej, roj lossis cua kom tau txais qee yam khoom siv. Ib hom kev kho cua sov, quenching tiv thaiv cov txheej txheem kub uas tsis xav tau, xws li kev hloov pauv theem, tshwm sim.
