Txheej txheem cej luam ntawm high-frequency quenching txheej txheem ntawm quenching tshav kub kho rau hluav taws xob daim ntaub txiav riam
Lub tshuab hluav taws xob txiav riam yog cua sov kho los ntawm lub tshuab quenching siab. Tom qab preheating kev kho cua sov ntawm 550 ° C, nws raug xa mus rau 860-880 ° C rau reheating kev kho cua sov. Cov cua kub kub txawv raws li qib steel sib txawv. 1250-1260 ° C, 1190-1200 ° C, 1200-1210 ° C, 1150-1160 ° C, feem. Cov nplej loj yog tswj ntawm qib 10.2-11. Thaum kawg, kev kho cua sov ntawm 550-560 ° C yog ua tiav.
Xyuas qhov hardness tom qab tempering, yog tias nws tshaj 64HRC, nws yuav tsum tau nce mus rau 580 ℃ tempering. Txheeb xyuas qhov ncaj ib los ntawm ib qho. Yog tias qhov kam rau siab dhau lawm, txuas ntxiv clamp thiab temper, tab sis overheating tsis pub.
