Desulphurising process for pig iron@ in blast furnace - by injection of coal dust and magnesium@ dust to which alkaline materials can be added

摘要

In a process for desulphurising pig iron mfd. in a blast furnace, coal dust and Mg dust are injected as a mixt., to which alkaline material can be added, into a region of the blast furnace above the melt region, i.e. at the point at which the iron originates. Al powder and/or carbide can replace the Mg. ADVANTAGE - Simplified and effective process
