Carborundum-containing High-carbon Materials Used in the Electro-thermal Metallurgy
The results of theoretical and applied research on the creation of a new class of carbonaceous reducing agents containing from 40 to 95% of carborundum are presented. As the initial carbonaceous raw materials, a wide range of materials of natural and technogenic origin, including screenings of crushing, coke, semi-coke, high-ash coals and waste products of metallurgical and fuel coals enrichment was considered. The transition to a two-stage production method (carborundum-containing reworked carbonaceous reductant at the first stage and final high-silicon alloys at the second stage) will significantly expand the raw material base and substantially reduce material and energy costs in technology.
