Steelmaking Process in Convert Ladle

With the oxidation of silicon, manganese, phosphorus, and carbon, which were provided by ferrosilicon, silicon manganese or silicon carbide, the temperature of the molten pool gradually increases, the brightness of the flame increases, the slag bubbles, and small iron particles splash out from the furnace mouth. At this time, the height of the oxygen lance should be lowered. In the middle of ...
