Hluav taws xob cov khoom siv raw khoom thiab kev kho mob - DRI ntau lawm, kub them ntawm molten hlau, thiab preheating ntawm seem hlau

DRI ntau lawm yog lub hom phiaj xav tau los ntxiv rau cov khoom seem hauv kev txhim kho ntawm ntau lub teb chaws uas tsis muaj cov khoom siv hlau tsis txaus. Raws li cov kws tshaj lij kev kwv yees, kev tsim khoom ntawm DRI yuav ncav cuag 105 lab tons hauv 10 xyoo. Piv nrog rau cov khoom seem hlau, DRI muaj qhov zoo dua qub thiab cov ntsiab lus ntawm cov khoom tsis zoo yog tsawg heev.
Nws tuaj yeem dilute thiab txo cov teeb meem hauv cov hlau, paub txog kev them nyiaj tas mus li, kev tsim cov slag sai, nruam melting thiab boiling ntawm molten pas dej ua ke, txhawb degassing, txo N cov ntsiab lus nyob rau hauv steel, thiab pab kom sai tsim ntawm ua npuas ncauj slag, yog li txo inclusions nyob rau hauv steel. Ua kom luv luv lub voj voog ntawm lub tshuab hluav taws xob thiab ua kom cov khoom muaj txiaj ntsig zoo xws li Ni thiab Mo.
Midrex Technology Co., Ltd. tau koom ua ke tsim cov txheej txheem luv luv hluav taws xob los ntawm cov hlau ore mus rau kub dov sawb, siv hlau ore (pellets) ua raw khoom, thiab tsim hluav taws xob txo hlau (DRI) los ntawm Midrex ntaus ntawv. Lub DRI yog kub them rau lub cub hluav taws xob ntawm qhov kub ntawm 600-700 degree (qhov kev ncua deb ntawm lub tshuab hluav taws xob tsheb thiab lub tshuab hluav taws xob ntsug yog li 100m). Txhua 100 degree nce hauv DRI kub tuaj yeem txuag tau 20kW · h / t ntawm hluav taws xob (siv 100 feem pua ​​​​DRI li raw khoom).
Raws li kev txheeb xyuas qhov xwm txheej tam sim no, cov ntawv thov kev lag luam tseem ceeb suav nrog cov txheej txheem Midrex, txheej txheem HYL2 III, txheej txheem Finmet, txheej txheem SL2RN, thiab txheej txheem Fastmet. Tom qab refining lub cub hluav taws xob molten hlau, nws tuaj yeem nkag mus rau CSP nyias slab nruam casting thiab dov ntau lawm kab los tsim kub dov sawb hlau. Cov txheej txheem no muaj kev siv hluav taws xob ntau dua li cov txheej txheem blast furnace converter, thiab tuaj yeem txo qis CO2 emissions los ntawm ib nrab.
Nyob rau hauv xyoo tas los no, vim lub cheeb tsam tsis txaus ntawm cov khoom siv hlau thiab cov nqi siab ntawm smelting tag nrho cov seem hlau, cov tuam txhab tsim cov cuab yeej siv hluav taws xob kub los hloov cov npua txias thiab qee cov hlau seem. Lub cev thiab tshuaj tshav kub uas coj los ntawm kev them nyiaj kub ntawm cov hlau molten tuaj yeem ua ntej lub sijhawm tsim cov slag thaum lub sijhawm yaj hauv lub thawv rauv, uas tuaj yeem txo cov hlau thiab hluav taws xob noj, thiab txo qis cov khoom seem hauv cov khoom siv raw.
Lub acceleration ntawm zus tau tej cov pace nyob rau hauv lub tam sim no hluav taws xob rauv kev lag luam tau coj mus rau ib tug qauv ntawm converter transformer, thiab qhov feem ntawm kub them molten hlau kuj nce. Lub DAI2WA hluav taws xob rauv cog hauv Nyij Pooj muaj cov hlau molten ntau dua 75 feem pua. Raws li qhov kub them piv ntawm cov hlau molten nce, qhov smelting zog noj ntawm tubular rauv txo. Thaum tus nqi them kub ntawm cov hlau molten nce los ntawm 40 feem pua ​​​​rau 65 feem pua ​​​​, txhua 1 feem pua ​​​​ntawm cov hlau molten yuav txo tau lub zog siv li ntawm 6kW · h · t -1.
Kev siv ntau ntawm cov hlau molten los yog kev tsim kho ntawm cov tshuab hluav taws xob tshiab hauv cov txheej txheem preheating ua rau cov txheej txheem ntawm cov txheej txheem hluav taws xob qub luv luv steel cog tsis luv luv, uas tsis tuaj yeem cuam tshuam cov kev siv ntau tshaj plaws hauv lub ntiaj teb, xws li ob chav furnace plhaub txoj kev, ntsug rauv txoj kev, pob tawb hom, thiab nruam hluav taws xob rauv. Kev tshem tawm cov flicker hauv daim phiaj hluav taws xob los txhim kho cov cuab yeej siv thev naus laus zis, kev txo cov plua plav, thiab tshem tawm cov khoom tsis zoo uas tsim los ntawm cov txheej txheem preheating ntawm cov seem steel tau zoo heev, thiab lub voj voog steelmaking tau luv heev.

Cov ntsiab lus saum toj no yog tsim los ntawm Superb heater Company, super heater. Kev tsim khoom tseem ceeb: cov khoom siv cua sov, ntsuas kub, cov khoom siv, cov khoom siv, thiab cov khoom siv raw xws li tubular rhaub, tubular rhaub, siv cua sov, ceramic rhaub, silicone roj hmab rhaub, thermocouples, thiab lwm yam.
