Abstract
Based on studies, the technological process results of the production of a complex calcium-containing ferrous alloy of waste blast-furnace slag using high-ash coal from the Saryadyr coal field and coal slurry from the Karaganda coal basin are presented. The study was conducted on the experimental site of the Abishev Chemical Metallurgical Institute using an ore-smelting furnace equipped with a 200-kV A transformer. The main task of the study was ensuring the complete reduction of all oxides of the charge comprised of blast-furnace slag, high-ash coal, and coal slurry in a continuous, stable, and easy-to-control slagless process.
