Lub Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (EAF) tau tawm los ua cov ntaub pua chaw sov thiab yooj yim dua li qhov eaf txheej txheem pab txhawb rau cov saw hluav taws xob hauv ntiaj teb? Los ntawm cov tsav tsheb hauv cheeb tsam, cov kab lus no tau rov ua li cas EAFs tau rov kho dua cov hlau kev lag luam yav tom ntej.
Daim duab loj: Lub ntiaj teb EAF ntau lawm
Raws li ntawm 2023, 28% ntawm lub ntiaj teb crude steel-kwv yees li 550 lab metric tons (mmt)-uas tsim los ntawmEAF Steel UaTxhua xyoo, raws li lub ntiaj teb steel koom nrog . Cov cim no tau nce zuj zus ntawm 22% hauv xyoo 2010, Tsav tsheb los ntawm kev txiav txim siab muaj thiab seem muaj.
Regional rhuav tshem (2023 cov ntaub ntawv):
