The Steel Industry Carbon Peak-Up and Decarbonization Action Plan ikuwunikiridwanso kuti apereke njira zazikulu zisanu.

China ipanga ndondomeko yochitirapo kanthu ndi mapu amsewu kuti ifike pachimake pamakampani azitsulo chaka chino, ndipo kupita patsogolo kumayang'aniridwa mosamalitsa, malinga ndi wailesi yachuma ya China Media Group, Tianxia Caijing.Pa 2021 (12) China Iron ndi Steel Msonkhano Wachitukuko Lachinayi, ndondomeko yokonzedwanso komanso yokonzedwa bwino ya ndondomeko ya carbon peak ndi kuchepetsa mpweya wa carbon yapangidwa, ndi njira zisanu zomwe zaperekedwa.

Malinga ndi nkhani yomwe idawululidwa pamwambowu, "Iron and Steel Industry Carbon Peak and Carbon Reduction Action Plan" yomwe idakonzedwa ndi maunduna ndi makomiti okhudzana ndi zokambirana zambiri zakunja, ndondomeko yaposachedwa yatha m'chikalata choyamba, Metallurgical Industry. Planning and Research Institute ngati gawo lothandizira kutenga nawo gawo pantchito yoyenera.Chandamale chamakampani a carbon peak poyambilira chimayikidwa ngati: isanafike 2025, makampani azitsulo akwaniritse kuchuluka kwa mpweya wa kaboni; Pofika 2030, makampani azitsulo akuyembekezeka kuchepetsa kutulutsa mpweya ndi mpweya. Matani 420 miliyoni ndi 30% kuchokera pachimake. Pali njira zisanu zokwaniritsira cholingacho, kulimbikitsa masanjidwe obiriwira, kusungitsa mphamvu ndi kuwongolera mphamvu zamagetsi, kukhathamiritsa kugwiritsa ntchito mphamvu ndi kapangidwe kazinthu, kumanga unyolo wamafakitale ozungulira chuma, ndikugwiritsa ntchito njira yopambana ya carbon low. matekinoloje.

 

Kunena zachindunji, polimbikitsa kamangidwe kobiriwira, tiyenera kukhathamiritsa masanjidwe a mafakitale, kuletsa mphamvu zatsopano zopangira, kuonjezera zokolola zobiriwira, ndikulimbikitsa zobiriwira nthawi yonse ya moyo. Makamaka, potengera mphamvu zopanga, akuluakulu akumbutsa posachedwa. Pamsonkhanowu, Li Yizhong, wapampando wa bungwe la China Federation of Industrial Economics, ananenanso kuti makampani azitsulo apitirizebe kutseka mphamvu zachikale. 74.5, ndipo zathu ndi 78.8.Zopeza zapachaka za ogwira ntchito zachitsulo zimaposa 100,000, ndipo kutulutsa kwachitsulo kwa munthu kumaposa matani 880.Izi zikusonyeza kuti Dongosolo lathu la 13 la Zaka zisanu layala maziko abwino a Mapulani a 14 a Zaka zisanu.Tikuyembekeza kupitiliza kuchotsa kumbuyo (kuthekera) ndikuwongolera (kuthekera) kwatsopano. "

 

Kupulumutsa mphamvu ndi njira zowongolerera mphamvu zowonjezera mphamvu kumaphatikizapo kulimbikitsa njira zamakono zopulumutsira mphamvu ndi zogwiritsira ntchito mphamvu zochepetsera mphamvu ndi mpweya wochepa, kupititsa patsogolo mphamvu yodzipangira yokha ya kutentha ndi mphamvu zowonongeka, komanso kugwiritsa ntchito matekinoloje anzeru a digito. ndi kamangidwe ka ndondomeko kumaphatikizapo kukhathamiritsa kwa mafuta aiwisi, kubwezeredwa kwa zitsulo zotsalira, kupanga mphamvu zatsopano ndi mphamvu zowonjezera.Luo Tiejun, wachiwiri kwa wapampando wa bungwe la China Iron and Steel Association, adanenanso pamsonkhanowo kuti katundu wotsalira ayenera kuwonjezeka. Makampani azitsulo amayenera kuchepetsa kutumizidwa kunja kwa zinthu wamba pomwe akusunga zogulitsa kunja kwa zinthu zamtengo wapatali, kuthetseratu kugulitsa kunja kwa zinthu zotsika mtengo powonjezera ma aloyi, ndikuwonjezera kutulutsa kwazinthu zoyambira monga ma billets ndi zitsulo zotsalira, " adatero.

 

Yin Ruiyu, katswiri wa maphunziro a ku China Academy of Engineering, ananena kuti ndondomeko ya mafakitale a zitsulo ndi kamangidwe ka zitsulo ziyenera kusinthidwanso.” Kapangidwe ka mafakitale azitsulo ku China akuyenera kusinthidwa pochepetsa chitukuko. .Tiyenera kugwiritsa ntchito njira yonse ya ng'anjo yamagetsi yamagetsi kuti tipange zida zazitali zomangira, m'malo mwa ng'anjo zazing'ono ndi zazing'ono, otembenuza kuti apange rebar, waya ndi zinthu zina zochulukirapo, ndiko kuti, kupanga masanjidwe oyenera a mphero zachitsulo kuzungulira. mzinda, kugwiritsa ntchito migodi ya m’tauni.”

 

Kumanga kozungulira chuma mafakitale unyolo zikuphatikizapo zigawo mphamvu kusakanikirana, zolimba zinyalala ntchito ndi kulimbikitsa kupanga olowa toughening.The ntchito yopambana otsika mpweya matekinoloje monga ntchito wa hydrogen smelting ndi mbali zina.Li Xinchuang, mlembi Party ndi injiniya wamkulu ya Metallurgical Industry Planning and Research Institute, idati kukwaniritsa kupanga hydrogen wobiriwira ndi kuchepetsa mtengo ndiye chinsinsi chakupambana kwaukadaulo wa hydrogen smelting technology.

 

Kuphatikiza pa njira zisanu izi, a Luo Tiejun adatsindikanso kuti kukwaniritsidwa kwa nsonga ya mpweya kuchokera pakuchepa kwa zitsulo. Komanso kuchepetsa mpweya wofanana ndi wochepa.Choncho kuti mufike pachimake cha carbon, chinthu choyamba kuchita ndikuyamba ndi kuchepa kwa kupanga zitsulo, makamaka kupanga chitsulo, chifukwa 70 peresenti ya mpweya wa carbon uli mu ng'anjo za sintering ndi kuphulika."
