Rolling Mill yog cov khoom siv tseem ceeb hauv kev ua lag luam, uas yog siv hlau, cov kab hlau tsis sib txawv, tab sis tuaj yeem faib ua cov theem hauv qab no:
Thawj, raw khoom npaj
Kev Xaiv Dawb
Raws li cov khoom yuav tsum xaiv Billet Nruam Casting, Ingot lossis slab, cov lus tshwj xeeb suav nrog cov nyiaj tshwj xeeb (150 × (tuab} mm).
Qhov tseem ceeb Performance index: Tshuaj lom neeg sib xyaw ua ke, tsis muaj qhov tawg nteg ntom nti thiab suav .
Pretricatment
Kub Rolling: Cov Billet yuav tsum tau rhuab los ntawm lub cua sov los ntawm cov cua sov cua sov rau {}}℃(steel) kom ua tiav Austenitizing.
Colding Txias: Cov kub dov lub coil yog pickled (hydrochloric lossis sulfuric acid) kom tshem tawm cov ntawv Oxide .

Cov dej siab ({15-20 mpa mpa mp
Ntxhib dov (khoob dov)
Siv lub zeb thim rov qab, lub billet yog dov mus rau ib qho kev sib tw tuab (e {{{} m {{2} .
Ib Leeg deformation ntawm 20-30}}%, Rolling Force txog 4000 Tons lossis Ntau Tshaj.
FINISHING DOV
Multi-Stand Nruam Rolling (xws li 7- sawv ntsug plaub-siab lub zeb), qhov kawg rolling kub yog tswj tau kub ntawm {}℃{{4 4}
Lub thickness qhov tseeb yog ± 0 {{. 1 hli, thiab cov yas ntawm lub phaj yog tsawg dua 1%.
Laminar Cua Txias
Lub hom phiaj ntawm lub hom phiaj (xws li Ferrite + PETLLITE) yog tau los ntawm kev tswj txias txias ntawm {1}℃/.
(2) cov txheej txheem txias txias
Annaling ua ntej dov
Annaling nyob rau hauv ib tug shrill lossis txuas ntxiv rauv (650-700℃c) Tshem tawm ua haujlwm ua haujlwm hnyav .
Multipass dov
Siv plaub / rau siab dov zeb, cov nqi txo qis ntawm 60-90%.
Dov Roj Lubrication txo cov coefficient ntawm kev txhuam mus rau 0.05-0.1.
Nruam Annealing
Cov cua kub ceev (10℃/ s) rau 800℃tom qab quenching, txhim kho lub phaj sib sib zog nqus (xws li kev sib sib zog nqus phaj r tus nqi ntau dua lossis sib npaug nrog 1 {3).
Thib peb, cov txheej txheem tom qab ua
Reel / Hlais
Kub Rolling: Hydraulic Coiler Chev (Txheej Txheej Nruab Nrab {}} m, nro {1} .
Colding txias: Ntev txiav los yog transverse txiav ntev (thev taus ± 0 . 5 hli).
Nto Kho
Galvanizing: kub dip plating (zinc txheej thickness 10-20 μm) .
Xim txheej: dov txheej + ci (zaj duab xis tuab {{1} .
Kev Soj Ntsuam Zoo
On-line thickness ntsuas ntsuas (qhov tseeb ± 1μm), laser ntaub ntawv ntsuas ntsuas (eddy kuaj cov nqi ntau dua lossis sib npaug nrog 99%) {3}
Plaub, Txheej Txheem Kev Ua Haujlwm Kev Ua Haujlwm
Ntse tswj tswj
Ua ntawv siv Dov Dag Zog-AGC (tsis siv neeg tuab tuab tswj), dabtsi yog khoov yob + channeling yob puab thev naus laus zis {}}
Kev txuag hluav taws xob thiab kev txo qis
Cov txheej txheem hloov chaw kub (DHCR) txo kev siv hluav taws xob rau 0 {}}}}}}} 8gj / t thiab nce cov txiaj ntsig mus rau 98.5%.
Kev txhim kho cov khoom tshiab
Siab lub zog hlau tswj dov thiab txias (tmcp) kom ua tiav tensile lub zog ntau dua los yog sib npaug rau 1200mpa.

Qhov siab tshaj plaws yob yob nyhav ntawm undergles coiler yog 30 tons
Los ntawm cov txheej txheem saum toj no, lub zeb tuaj yeem hloov kho cov roj raw ua kom tau raws li cov txheej txheem ultra, thiab cov nqi siv hluav taws xob ncaj qha thiab cov khoom siv ceev thiab qis dua kev noj haus.
