En-gjs -500-7 dib hlau

En-gjs -500-7 Down Hlau Taw Qhia:
En-gjs -500-7 Cov hlau ua kom zoo nkauj tau tsim tawm qee qhov kev ua tau zoo, nws yog qhov ua tau zoo, muaj zog, hnav tsis kam ua ntawm cov khoom siab. Nodular cas cam khwb cia hlau yog tau los ntawm kev kho mob thiab kev kho mob inoculation, tshwj xeeb tshaj yog ua rau muaj zog dua li cov hlau siab dua li cov hlau. Cov hlau yas tau tsim sai sai rau hauv ib qho cam khwb cia hlau khoom siv thib ob tsuas yog rau hlau hlau thiab dav siv. Qhov thiaj li hu ua "Hlau es tsis txhob siv hlau" feem ntau yog hais txog cov hlau can.

En-gjs -500-7 Kev Kho Kub Kub Kub Qhia txog kev kho kom sov thiab cov hlau duab ntawm cov hlau ductab:
1, annealing: tau txais ferrite matrix, txhim kho kom muaj zog, kev sib cav sib nrawm, kev nyuaj siab, txhim kho kev txiav tawm kev ua haujlwm.
2, Li qub: Tau txais Pearlite Matrix, txhim kho lub zog thiab kev tawm tsam. 3, Tempering: Tau txais cov qauv matrix ntawm cov qauv kev ua haujlwm, xws li kev ua haujlwm siab, kom tsis txhob tawg thaum kho cua sov, xws li Ntxaiv, crankshaft, iav, thiab lwm yam 5. Metallogrographic koom haum; Ferrite + Petlite.
