Kev kho cua sov txheej txheem ntawm kev kub ceev steel yog qhov nyuaj, uas yuav tsum tau mus los ntawm cov txheej txheem xws li quenching thiab tempering. Quenching feem ntau yog ua nyob rau hauv ob theem vim nws tsis zoo thermal conductivity. Ua ntej, preheat ntawm 800 ~ 850 degree (kom tsis txhob ua rau muaj kev ntxhov siab loj), tom qab ntawd sai sai rau lub quenching kub ntawm 1190 ~ 1290 degree (ntau hom muaj qhov sib txawv ntawm qhov kub ntawm qhov siv tiag), thiab tom qab ntawd roj txias, cua txias lossis roj puv. cua txias. Lub qhov cub ntsev yog siv rau cua sov hauv lub hoobkas, thiab lub tshuab nqus tsev vacuum kuj tau siv dav. Tom qab quenching, ib feem ntawm khaws cia austenite (kwv yees li 30 feem pua) tsis tau hloov mus rau hauv martensite, uas cuam tshuam rau cov khoom ntawm high-speed steel. Txhawm rau hloov cov austenite residual thiab ntxiv txhim kho qhov tawv thiab hnav tsis kam, feem ntau yuav tsum tau ua 2 ~ 3 zaug ntawm tempering ntawm 560 degree, thiab txhua zaus tuav 1 teev.
Kev tsim khoom thiab kev tsim khoom: feem ntau yog hluav taws xob cub hluav taws xob siv rau kev tsim khoom, thiab cov hmoov metallurgy txoj kev siv los ua cov hlau nrawm, kom cov carbide sib npaug ntawm cov matrix raws li cov khoom me me, uas txhim kho cov kev pab cuam lub neej.
Daim Ntawv Thov: Nws yog siv los tsim ntau yam cuab yeej txiav. Xws li cov cuab yeej tig, laum, hob, tshuab pom hniav thiab pwm nrog cov kev xav tau siab.
