摘要:
A molten bath-based direct smelting process comprises controlling the process conditions in a direct smelting vessel so that molten slag in a molten bath of metal and slag in the vessel has a viscosity in a range of 0.5-5 poise when the slag temperature is in a range of 1400-1550° C. in the molten bath in the vessel.
