Forged sib tsoo pob ntau lawm yuav tsum

Kev sib tsoo cov khoom yuav ncav cuag 125 hli los yog ntau tshaj ntawm cov lus qhia, thiab lawv xav tau ua lag luam loj. Nyob rau tib lub sijhawm, kom txo tau qhov kev sib tw ntawm lub sib tsoo pob, nws yuav tsum tau hais tias lub pob zeb sib tsoo muaj kev nyuaj siab dua, thiab xav tau lub neej muaj kev kub ntxhov ntau dua. Nyob rau hauv cov ntsiab lus ntawm cov khoom siv, nws yuav tsum muaj nyob rau hauv qhov ntau ntawm 0.7% rau 0.85%. Tsis tas li ntawd, lub tseem zog austenite ua ntej lub sib tsoo pob yog quenched yuav tsum me me, thiab qib siab siab npaum li cas yog siab tshaj 7 theem.

Nws yuav tsum them sai sai rau nws siv:

(1) Txheej txheem ntau ntau ntawm kev sib tsoo cov khoom sib forging yog tsuas yog forging. Nws tuaj yeem muaj zog tawv los ntawm kev sib piv thiab kev kho cua sov ntawm qee cov kev ua txhua yam, thiab qhov sib txawv ntawm sab hauv thiab sab nraud yog me me, thiab nws tsis yooj yim los rhuav tshem thiab lwm yam teeb meem. Tsis tas li ntawd, lub pob zeb sib tsoo ntawm qhov sib tsoo pob zeb yuav raug txo, thiab nws tuaj yeem tswj tsis pub dhau 1%.

(2) Txij li ntawm qhov kev sib tsoo ntawm lub forged sib tsoo pob me me, cov txhuas hmoov ntawm zeb tuaj yeem nce thiab tus nqi ntawm cov nyiaj raug txo kom tsawg, qhov no ua kom zoo dua ntxiv ntawm cov khoom siv ntawm cov zeb.

(3) Lub qauv ntawm kev sib tsoo ntawm lub forged sib tsoo yog ib txoj hauv kev zoo ntawm rab koob martensite uas muaj kev kub ntxhov. Yog li, nws yog tib yam li cov hnav tsis kam ntawm tus foundry sib tsoo pob, ces tus nqi ntawm no hom sib tsoo pob yog tsawg tshaj li ntawm cov casting sib tsoo pob, thiab tus nqi sib tsoo kuj yog txo. grindingballsmedia.com
