Carborundum-bearing reducing agents in high-silicon alloy production

Resumo

The creation of a new class of carbon reducing agents containing 40–95% carborundum is considered. The carbon is derived from a wide range of natural and industrial materials, including mill siftings, coke, semicoke, high-ash coal, and coal-enrichment wastes. By two-stage production—first of carborundum-bearing reducing agents and then of high-silicon alloys—the range of possible raw materials may be markedly expanded, and the costs of materials and energy in alloy production may be significantly reduced.
