The Peculiarities of Smelting of Wear-Resistant Cast Iron IChH28N2 in the Induction Crucible Furnace IChT10

Abstract:

Wear-resistant cast iron smelting is produced in electric arc furnaces, due to the use of steel scrap in metal charge, ferrochrome and refund if there is one. Scrap of cast iron with the necessary chemical composition is not present because the proportion of manufacturing parts from wear-resistant cast iron is very small. Thus, there is no opportunity to form castings of wear-resistant cast iron using foundries equipped only with induction crucible furnaces of industrial frequency (IChT), since the furnace is designed for melting temperatures not above 1500 °C. In addition, the lining of induction furnaces of industrial frequency is made of quartzite, which provides the necessary durability when operating at temperatures not above 1500 °C. The ability to manufacture blanks from wear-resistant cast iron gives an additional opportunity to expand the range of orders and prevent a reduction in production in factories equipped only with the smelting furnaces of the IChT. The article describes the peculiarities of smelting cast iron IChH28N2 in the furnace IChT10 with acid lining. The technology of conducting melting on pure charge materials without use of cast iron scrap and return is briefly described.
