Technological Aspects of the Use of Lump Anthracite in Blast-Furnace Smelting

Abstract

On blast furnaces that have never been operated with the injection of pulverized-coal and that first need to be provided with high-quality iron-ore-bearing materials and coke, the use of a technology that charges lump anthracite into the furnaces can significantly reduce coke consumption and the cost of making pig iron. The technology is especially effective if the furnace’s productivity is limited by problems in obtaining the desired finished product and it has to be operated at lower speeds or it runs more efficiently under such conditions.
