Smelting Reduction of a Monocharge

Abstract

The existing two-stage technology used to make iron and steel is based on the use of hot reducing gases, which results in the formation of waste gases and dust and creates an environmental problem. The results obtained from an analysis of metallurgical processes that involve smelting reduction are used to propose a new technology based on the smelting reduction of a monocharge contains carbon and oxides of metals. The monocharge is composed in such a way as to ensure complete reduction of the metals while also preventing their carburization. A monocharge was subjected to smelting reduction to obtain the world’s first specimens of directly-made alloy steel without the intermediate conversions – the production of pig iron and metallized semifinished products.
