Abstract

An estimation of the reduction process was given in the chemical reserve zone of the blast furnace. It is shown that the presence of finely ground solid fuel in pellets provides the development of complex reduction in this zone and reduces the level of direct reduction due to metalizing. The results of the investigation of metallurgical properties of self-reducing pellets and the results of blast furnace smelting are given. The estimation of usage effectiveness of self-reducing pellets during pulverized coal fuel injection is provided
