operatingBF–BOF Integrated route · Meili, Asia Pacific, China
Changshu Longteng Special Steel Co Ltd makes steel by the integrated route: iron ore is smelted into liquid hot metal in a blast furnace, then refined into crude steel in a basic oxygen furnace. Alongside the ore-based route, the plant runs an electric arc furnace that melts scrap and other metallics. The liquid steel is solidified into semi-finished shapes by continuous casting. The plant has a crude steel capacity of about 2.2 million tonnes per year.
