Cov txheej txheem ntawm kev tsim khoom

Cov txheej txheem ntau lawm ntawm kub-rolled steel chev yog qhov txuas tseem ceeb hauv kev tsim cov hlau. Nws tsuas yog siv cov hlau billet rau hauv cov phaj uas yuav tsum tau ua los ntawm qhov ntsuas kub-kub. Hauv qab no yog nws cov kauj ruam tseem ceeb:
Raw Khoom Npaj
Siv billet txuas ntxiv billet lossis thawj zaug dov billet li cov khoom siv raw, thiab cov billet thickness feem ntau yog 150mm.
Lub billet yog saum npoo huv (xws li nplaim taws tu los yog kev sib tsoo tshuab) kom tshem tawm cov roj oxide thiab tsis xws luag.
Tso kev sov
Lub billet xa mus rau ib kauj ruam-nqaj cua sov sov sov thiab ua kom sov rau 1100-1300 ℃ ua kom lub billet mus txog Austenitizing kub thiab txhim khu kev planticity.
Tswj lub caij sov thiab kub ua kom sov kom tsis txhob overburning lossis tsis txaus kub.
Rough Dov
Lub billet thickness yog txo rau 30-50mm los ntawm kev thim rov qab regic dov plhom zeb (xws li ob-yob lossis plaub-yob los tsim cov nyiaj nruab nrab.
Cov dej siab xav tau dej siab yuav tau ua tom qab txhua lub sijhawm yob kom tshem tawm cov txheej oxide.
FINISHING DOV
Cov nyiaj nruab nrab hauv nruab nrab nkag mus rau hauv ib lub pob zeb (feem ntau 6-7 plaub-yob lossis 6-yob mills), thiab yog maj mam thined rau lub hom phiaj tuab (xws li 1.2-25mm) los ntawm kev dov mus txuas ntxiv.
AGC (tsis siv neeg thickness tswj) thiab lub phaj tswj thicking yog siv los xyuas kom meej qhov tseeb ntawm qhov tseeb thiab phaj ncaj ncaj.
Cov chais yuav tsum tau txias thiab lubricated thaum lub sijhawm dov kom tiv thaiv kev deformal deformation thiab hnav.
Cua txias
Ib qho Laminar txias zog yog siv los ua kom txias txias ntawm qhov kawg yob los ntawm kev tswj cov dej ntim thiab txias tus nqi (xws li lub sijhawm txias (xws li 30-50 ℃ / s).
Tus txheej txheem txias ncaj qha cuam tshuam rau microstructure (xws li ferrite thiab hlaws piv) thiab cov khoom siv tshuab ntawm cov hlau cheel.
Coiling
Lub steel sawb yog dov rau hauv ib tug steel che hlau los ntawm cov menyuam yaus thiab cov leeg yog tswj hwm ntawm 100-500n / mm² kom ntseeg tau tias cov duab coil yog nruj thiab tsis muaj xoob xoob.
Lub coiling kub feem ntau yog tswj ntawm 550-700 ℃ los ua kom ua tiav kev ua tau zoo.
Tom ntej kev kho mob
Nto Kho: Pickling tshem oxide nplai, lossis galvanizing, txhuas plating thiab lwm yam kev kho mob.
Ib tug anerting: Txhim kho cov ntaub ntawv ductility (xws li recrystallization analing ua ntej dov txias).
Du: Tshem tawm cov txiaj ntsig platform thiab txhim tsa saum npoo ua tiav los ntawm kev txo tus nqi me me dov.
Kev Soj Ntsuam Zoo Thiab Ntim: Khij qhov loj me, cov khoom siv neeg kho mob thiab cov khoom zoo, thiab yob, pob thiab cim raws li cov neeg siv khoom.
