- UPhuculo lweendleko ze 5000 Uthotho
I ukuqhubeka nokuqengqeleka (CCR) inkqubo ithatha indawo yemveli ingot eshushu rolling, ukunciphisa umjikelo wemveliso ukusuka 15 iintsuku ukuya 2 iintsuku (86.7% ukunciphisa) kunye nokunciphisa ukusetyenziswa kwamandla ngo 30% (ukusuka kuma-500kWh/toni ukuya kuma-350kWh/toni). Ukulawulwa ngokuchanekileyo komxholo we-magnesium (4.0%-4.5%) iqinisekisa amandla okuqina ≥310MPa ngelixa unciphisa iindleko zemathiriyeli ekrwada ngo 12% (ukusuka 32,000 RMB/toni ukuya 28,000 Rmb / ton). Ukusetyenziswa kobuninzi kwiipaneli zomzimba zezithuthi zorhwebo zorhwebo (I-E.G., iilori zokuhambisa ezidolophini) ilindelwe ngu 2024.
