Abstract

An appreciation of the reduction process was given in the chemical reserve zone of the blast furnace (900-1200 °C). It's shown, that presence of finely divided solid fuel in pellets provides the development of a complex reduction in the area and reduces the degree of direct recovery by metallization. The results of the investigation of metallurgical self-reducing pellets properties and the results of the blast furnace operation were carrying out. An appreciation of effect of usage the self-reducing pellets during blowing the apulverized coal.
