Lub tuam txhab npog thaj tsam ntawm ze li ntawm 70,000 square metres, nrog thaj tsam ntawm 33,260 square metres thiab lub Hoobkas thaj tsam ntawm 24,051 square meters. Tam sim no nws ntiav kwv yees li 300 tus neeg ua haujlwm thiab muaj nyob ib ncig ntawm 500 cov khoom siv ua haujlwm tshwj xeeb.
Hluav taws xob Arc Rauv (EAF) yog ib hom khoom siv hlau uas siv hluav taws xob los ua kom kub kub arc los ntawm graphite electrodes kom yaj steel seem lossis ncaj qha txo cov hlau. Nws yog cov cuab yeej tseem ceeb ntawm cov khoom siv niaj hnub luv luv - txheej txheem steelmaking, tshwj xeeb tshaj yog tsim rau steel ntau lawm nrog cov khoom siv raw, uas muaj kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab hloov tau yooj yim.
1. Lub hauv paus ntsiab lus ua haujlwm
Arc cua sov: siab-kub arc (kub mus txog 3000℃lossis ntau dua) yog tsim los ntawm graphite electrode thiab nqi (khoom, thiab lwm yam), thiab cov hlau yog melted ncaj qha los ntawm arc tshav kub.
Resistance cua sov: Tom qab tsim lub pas dej molten, cov hluav taws xob tam sim no dhau los ntawm cov kua hlau ua kom muaj cua sov, uas ntxiv rau cov hlau molten.
Chemical zog pab: tshuab pa combustion los yog ntxiv carbon hmoov thiab lwm yam tshuaj tiv thaiv kom tso cua sov, pab ua kom sov.
2. Lub ntsiab qauv
Rauv lub cev: Nws yog tsim los ntawm steel plhaub lined nrog cov khoom refractory thiab muab faib rau hauv lub cub tawg hauv qab, rauv phab ntsa thiab lub qhov cub npog.
Electrode system: 3 lifting graphite electrodes (peb-theem alternating tam sim no), lub arc ntev yog tswj los ntawm kev kho cov electrode txoj hauj lwm.
Tilting ntaus ntawv: qaij rau pem hauv ntej thaum hlau tawm, qaij rov qab thaum slag tawm.
Dedusting system: Kov cov pa luam yeeb thiab plua plav tsim nyob rau hauv cov txheej txheem smelting (xws li hnab desusting lossis electrostatic dedusting).
Cov cuab yeej pabcuam: Oxygen phom, carbon hmoov tshuab tshuab, alloy charging system, thiab lwm yam.
3. Smelting txheej txheem
Kev Them Nyiaj: Cov khoom seem lossis DRI raug thauj los ntawm lub qhov cub lossis lub qhov rooj.
Melting theem: cov electrodes yog energized los tsim ib tug hluav taws xob arc, thiab cov seem yog maj melted (lub zog noj nyiaj rau 60% -70% ntawm tag nrho cov txheej txheem).
Oxidizing lub sij hawm: Oxygen tshuab tshem tawm impurities (xws li C, Si, P, thiab lwm yam), thiab ua npuas ncauj slag yog tsim los npog arc los txhim kho thermal efficiency.
Txo lub sij hawm (yeem): ntxiv alloy los kho qhov muaj pes tsawg leeg, desulfurization, deoxidation.
Tawm ntawm cov hlau: steel yog nchuav rau hauv lub ladle kom nkag mus rau hauv cov txheej txheem refining.
4. Technical yam ntxwv
Cov ntaub ntawv yooj yim: feem ntau yog seem, tuaj yeem sib xyaw nrog cov hlau molten, DRI, kub briquetted hlau (HBI), thiab lwm yam.
Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig: kev siv hluav taws xob txog li 350-400 kWh ib tuj ntawm cov hlau, CO₂ emission txo los ntawm ntau dua 60% piv nrog cov tsoos blast furnace - txheej txheem converter.
Kev tsim tawm sai: lub voj voog smelting ntawm ib lub cub tawg yog li 30-60 feeb, uas yog tsim rau me me - ntau thiab ntau ntau yam.
Qib siab ntawm automation: Niaj hnub nimno EAF tau txais kev tswj hwm kev txawj ntse los ua kom zoo zog, muab cov pa oxygen thiab them nyiaj.
5. Kev tiv thaiv ib puag ncig
Ua ntej-kev kho cov seem hlau: tshem tawm cov impurities xws li roj thiab tsis yog- ferrous hlau.
Flue gas recovery: Siv cov khib nyiab kub boiler los tsim hluav taws xob thiab ntes dioxin thiab lwm yam pa phem.
Kev kho Slag: steel slag yog rov siv dua rau cov khoom siv hauv tsev lossis cov ntaub ntawv hauv kev.
