Increasing the Efficiency of Synthetic Iron Production by the Use of New Kit Lining

The production of synthetic iron castings in Russia comprises 50% all alloys produced; therefore, increasing their smelting efficiency is an urgent task the industry. This process depends primarily on industrial frequency induction crucible furnaces using acid lining. In present study, properties quartzite, which forms basis such a lining, were investigated. An analysis proposed variants for changing composition lining use at temperatures 1550–1600 °C was conducted. Following preliminary temperature treatment raw then subjected to sintering regime, we determined conditions under it possible obtain phase state, allowing operation above 1450 °C. We electrocorundum two fractions as additive traditional testing new liner cast melting furnace with single steel scrap-metal filling assessed, required increased amount carburizing agent. positive results obtained can be explained by study spent withstood 345 methods genophasic rent analysis. test are based conducted finished coating product.
