Isicelo ezimotweni zezentengiselwano ezisindayo ezindaweni ezisogwini (E.g., ogandaganda basechwebeni) kungenzeka nge 2025.
- Ukuthuthukisa Izindleko ze 5000 -Uhume
I ukuphonsa okuqhubekayo nokugoqa (I-CCR) inqubo ithatha indawo yendabuko ye-ingot hot rolling, ukunciphisa umjikelezo wokukhiqiza kusuka 15 izinsuku ukuze 2 izinsuku (86.7% ukunciphisa) kanye nokunciphisa ukusetshenziswa kwamandla 30% (ukusuka ku-500kWh/ton ukuya ku-350kWh/ton). Ukulawulwa okunembile kokuqukethwe kwe-magnesium (4.0%-4.5%) iqinisekisa amandla aqinile ≥310MPa ngenkathi inciphisa izindleko zempahla eluhlaza nge 12% (ukusuka 32,000 RMB/ton kuya 28,000 RMB / TON). Ukusetshenziswa kweMisa kumaphaneli omzimba wezimoto zokuhweba ezongayo (E.g., amaloli okusabalalisa amadolobha) kulindeleke ngu 2024.
