Forging thiab tempering cov qauv ntaub ntawv

45 cov steel hlau, kub thiab ua txias kev zoo, txhua yam zoo zog thiab tsis tshua muaj nqi, qhov dav, ces yog lug siv. Nws tsis muaj zog biggest yog tsis hardenability, loj loj thiab siab yuav tsum workpieces yuav siv tsis tau. 45 hlau quenching kub ntawm cov A3 + (30 ~ 50), thiab rau cov uas ua lag luam, cov txwv lub no feem ntau yuav. Quenching kev kub siab yuav ua rau cov cua sov ceev, workpiece kom oxidation deg, thiab ua kom tau hauj lwm efficiency. Workpiece homogenization austenitic, uas yuav tau txhais tias lub sij hawm. Yog hais tias lub sij hawm cov chaw thau khoom tuav tau, tsim nyog yuav tau yuav tsum tau txhaj. Txwv tsis pub, tsis muaj hardness vim muaj cua kub sis tsis ncaj tej zaum yuav tshwm sim tau. Tuav lub sij hawm no mus ntev lawm, ntxhib nplej yuav tshwm, oxidation thiab decarburization ntawm loj ills rau quenching zoo. Rau peb pom, xws li them ntau tshaj raws li cov txheej txheem tsab ntawv, hauv tsev kom sov tuav lub sij hawm uas yuav tsum tau mus cuag 1/5.
