SS400 pav ca hlau

SS400 Ca Hlau Cov Khoom Siv Khoom Ntau Lawm

Raw Khoom Npaj: Firstly, Hlau ore tau muab rho tawm los ntawm cov mine, thiab tom qab crushing, sib tsoo, sib nqus, impurities raug tshem tawm cov roj high-ee tsom. Tom qab ntawd cov thee yog ua kom zoo rau qhov kub kom tau txais coke, uas yog cov roj tseem ceeb hauv cov txheej txheem tawg yooj yim.

Moj tej tawg ua rauv smelting: Raw cov ntaub ntawv xws li hlau thiab pleev cov kab mob flux thiab Coke tau ntxiv rau cov hlau ua kom tawg kom txo cov roj ntsha molten. Cov Hlau Molten tawm los ntawm lub zog tawg yog kho nrog desulfurization thiab slag tshem tawm kom txhim kho cov hlau ntawm molten.

Steelmaking: Ntxiv cov tshuaj kho cov hlau molten lossis hluav taws xob tshem tawm, tshem cov roj av, ntxiv rau cov pa roj ntsha, thiab ntxiv kom tau txais cov hlau uas yuav tsum tau ua tiav. Deagidizing, deslagging thiab kho cov lus sib xyaw ntawm cov hlau molten los txhim kho qhov zoo ntawm cov hlau tsis zoo.

Nruam casting: Steel tau txhaj rau hauv lub crystallizer lossis txuas ntxiv tshuab ua caste thiab txias rau hauv cov tsiaj. Txoj kev no ua kom muaj kev ua tau zoo thiab txuas ntxiv ntawm cov hlau thiab txo cov kev tsis xws luag thiab seem ntawm cov txheej txheem ntau lawm.

Dov: Cov Cast cam khwb cia yog dhau los ntawm ib qho ntawm cov xaim mills rau cov yas ua los ua cov qauv tiaj tus qauv hlau thiab qhov loj me. Cov txheej txheem Rolling feem ntau muaj ob theem, qhib billened thiab tau muab cov khoom siv hluav taws xob ntau dua, thiab ua tiav cov khoom siv hluav taws xob siab, thiab cov khoom siv ua tiav ntxiv rau cov tuab tuab thiab ua kom zoo dua.

Cua txias thiab ncaj: Tom qab dov, lub tiaj tus txheej txheem txias thiab ncaj rau tshem tawm sab hauv kev ntxhov siab thiab txhawm rau txhim kho txoj kev ncaj thiab precision ntawm lub tiaj tus.

Lub xov: Qhov no suav nrog kev txiav, ncaj kho, kev kho deg thiab cim ntawm cov hlau tiaj tus kom paub meej tias nws ua tau raws li cov lus qhia tshwj xeeb thiab ua kom zoo. Nws kuj tseem suav nrog kev kuaj xyuas qhov zoo thiab qhov tseeb ntawm lub tiaj tus hlau kom ntseeg tau tias nws ua tau raws li cov neeg siv khoom.

SS400 pav ca hlau Cov Khoom Sib Koom Tes

Lub ntsiab tshuaj lom neeg muaj pes tsawg leeg ntawmSS400 pav ca hlausuav nrog cov pa roj carbon (c), silicon (si), manganese (mn), leej faj (p) thiab phosphorus (p).

Carbon (c): Cov ntsiab lus feem ntau yog nruab nrab ntawm {{{0}}}}}}}. 05% thiab 0.20% thiab 0.20% thiab 0.20% thiab 0.20% thiab 0.20% thiab 0.20%

Silicon (si): Cov ntsiab lus feem ntau tsis tshaj 0. 35%, pab txhim kho lub zog thiab tawv ntawm cov hlau phaj.

Manganese (mn): Cov ntsiab lus yog kwv yees li ntawm 1.40% thiab 1.75%, nce silicon thiab manganese tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau phaj.

Sulphur (s): Cov ntsiab lus feem ntau tsis tshaj 0. 05%}. 05%, nws cov ntsiab lus yuav tsum tau tswj hwm hauv qee qhov kev ua tau zoo ntawm cov hlau phaj.

Phosphorus (p): Cov ntsiab lus feem ntau tsis tshaj 0. 045%, nws cov ntsiab lus tseem yuav tau tswj hwm hauv qee qhov kev ua tau zoo ntawm cov hlau phaj.
