Txoj kev ntawm ntsuab transformation ntawm steel kev lag luam

Cov txiaj ntsig zoo kawg nkaus tau ua tiav hauv kev txuag hluav taws xob thiab txo qis emissions hauv kev lag luam steel

Lub 18th National Congress of the Communist Party of China suav nrog kev nce qib hauv ecological rau hauv tsib-hauv-ib txoj kev npaj rau kev tsim kev sib raug zoo nrog Suav cov yam ntxwv, thiab tau hais meej tias peb yuav tsum ua kom muaj kev vam meej hauv zej zog.Kev lag luam hlau thiab hlau, raws li kev lag luam yooj yim ntawm kev txhim kho kev lag luam hauv teb chaws, siv kev txuag hluav taws xob thiab kev txo qis emissions raws li cov kev taw qhia tseem ceeb ntawm kev ua lag luam, tsis tu ncua pioneering thiab forging ua ntej, thiab tau ua tiav cov txiaj ntsig zoo kawg li.

Ua ntej, hais txog kev tiv thaiv kev ua qias tuaj thiab kev tswj hwm, kev lag luam steel tau ua ntau yam kev hloov pauv keeb kwm txij li xyoo 2012.

Cov keeb kwm kev ua tiav tau ua tiav hauv kev sib ntaus sib tua los tiv thaiv lub ntuj xiav, txhawb kev loj hlob ntsuab thiab zoo ntawm kev lag luam steel.Piv txwv li, flue gas desulfurization, denitrification thiab plua plav tshem tawm cov chaw xws li sintering, coke ncu thiab cov chaw tsim hluav taws xob uas siv hluav taws xob rau nws tus kheej tau dhau los ua cov cuab yeej siv, thiab cov qauv ua pa phem ntau dua li cov teb chaws tsim kho xws li Nyiv, Sab Qab Teb. Kauslim thiab Tebchaws Meskas.Kev tswj kom zoo thiab kev kho mob ntawm cov emissions tsis sib haum ua rau cov tuam txhab steel coj mus rau qhov tshiab;Kev txhawb zog ntawm kev tsheb ciav hlau thiab lub zog tshiab cov tsheb thauj khoom hnyav tau txhim kho cov kev thauj mus los huv ntawm kev sib txuas hauv kev lag luam hlau thiab hlau.

Cov kev ntsuas no yog cov kev ntsuas tseem ceeb ntawm kev tswj huab cua hauv kev lag luam steel. "Nws Wenbo tau hais tias raws li kev txheeb cais tsis tiav, tag nrho cov peev txheej hauv kev hloov pauv ntawm cov pa hluav taws xob tsawg ntawm cov tuam txhab steel tau tshaj 150 billion yuan.Los ntawm kev siv zog tas mus li, Ib tus lej ntawm A-theem kev lag luam nrog kev ua haujlwm ib puag ncig thiab A tus lej ntawm 4A thiab 3A qib kev lag luam kev lag luam tau tshwm sim hauv kev lag luam hlau thiab hlau, tso ib lub hauv paus ruaj khov rau kev tsim kho vaj tse hauv zej zog thiab ua rau lub ntuj xiav. tob dua, pob tshab thiab ntev dua.

Thib ob, hais txog kev txuag hluav taws xob thiab kev txo qis, kev ua tiav zoo kawg nkaus tau ua tiav hauv kev txuag hluav taws xob thiab kev txo qis los ntawm kev txuag hluav taws xob tas li, kev txuag hluav taws xob, kev tswj hluav taws xob txuag thiab kev txuag hluav taws xob.Raws li kev txheeb cais, xyoo 2021, kev siv hluav taws xob zoo ib tuj ntawm lub teb chaws tseem ceeb ntawm cov tuam txhab loj thiab nruab nrab steel tau mus txog 549 kg tus qauv thee, nqis txog 53 kg txheem thee piv nrog xyoo 2012, txo qis ze li 9%.Nyob rau tib lub sijhawm, xyoo 2021, cov khoom siv hluav taws xob pov tseg thiab hluav taws xob rov ua dua theem ntawm cov tuam txhab loj thiab nruab nrab steel tseem ceeb tau txhim kho zoo.Piv nrog rau xyoo 2012, qhov kev tso tawm ntawm coke qhov cub roj thiab blast furnace gas txo qis li ntawm 41% thiab 71% raws li, thiab cov hlau rov qab cov nqi ntawm cov roj hloov pauv tau nce li ntawm 26%.

"Ntxiv rau qhov kev txhim kho ntawm cov ntsuas no, lub zog tswj hom ntawm hlau thiab steel kev lag luam kuj maj mam hloov los ntawm kev paub txog kev tswj mus rau niaj hnub kev tswj, los ntawm ib tug tib lub zog txuag department tswj mus rau kev lag luam kev sib koom ua ke zog txo transformation, los ntawm dag cov ntaub ntawv statistical. tsom xam rau digital, txawj ntse transformation.
