摘要
In a process for injecting a fine-grain carbon carrier including ash-bearing bituminous or hard coal into a blast furnace hearth, use is made of a mix of fine-grain bituminous coal and at least one other solid fine-grain ash-bearing carbon carrier. The composition of the mix is so selected that the degree of basicity of the overall resulting ash of the mixture is adapted to the degree of basicity of the furnace slag.
