Experimental Research Regarding Decreasing Of Fabrication Costs Of Metallurgical Coke By Using Non-Coking Coals And Recycling Of Small Coal

The present article addresses an important subject in the metallurgical industry, the unconventional technological processes of producing metallurgical coke. The fabrication principle presented in the article refers to the utilization of non-coking coals and recycling of small coal. The purpose of the laboratory experiments was to determine the parameters that condition the possibilities of degreasing bituminous coal with certain additions. By adding small coal, an increase in coke quality is obtained. In comparison with the semi-coke, the addition of small coke with the same grain size has a more powerful degreasing effect. The coke's grain size also has an influence on the degreasing capability in the sense that the finer the coke the more degreasing it becomes, more active. Utilizing small coke in the load requires smaller quantities the finer it is grinded.
