QUALITY OF HIGH-CARBON WIRE ROD FROM STEEL OBTAINED BY VARIOUS SMELTING METHODS

Abstract

This article considers modern methods of steel production and their impact on the quality of wire rod made from grade 80 steel and applied for hardware products manufacturing. From research data on the chemical composition of wire rod produced by the oxygen-converter method and in an arc steelmakingfurnace, it can be noted that, in general, the chemical composition of the wire rod meets the requirements, while the steel produced in the converter contains less phosphorus, sulfur and non-ferrous metal impurities and nitrogen. This fact should have a beneficial effect on the ductility of the wire during further cold drawing. The analysis of the quality indicators of the finished wire rod produced from billets obtained according to various technological schemes showed that the integral quality indicator is at the same level when using optimal modes of out-of-furnace processing and continuous casting of steel.
