Production Practice of C82DA High Carbon Steel Wire Rod for Conversion to Wire

Abstract

Based on design of chemical composition, reasonable adjustment and optimization of smelting and continuous casting process, reheating process, rolling process and cooling process etc., Anyang Iron And Steel Group Co., Ltd. produced successfully Φ 5.5 mm high carbon steel wire rod grade C82DA for conversion to wire by 100t converter-high speed wire rod mill. The sorbitic metallographic structure of rod reached more than 90%. The wire rod is in good mechanical performance with the range of tensile strength deviation of less than 70Mpa for same heat, same nominal diameter and same rolling system. It can fully satisfy the requirements of customers.
