本项目采用节能环保专利工艺技术生产轴承钢GCr15线材8万t,产品实物质量达到国内领先水平,累计为企业及社会创效达6000万元。根据轴承钢GCr15的特点,并结合鄂钢现有设备状况,研究开发了轴承钢GCr15线材的“80%铁水+废钢全程吹氧不供电”冶炼+“精轧过盈控制+三阶段控冷”生产工艺。该工艺技术属国内首创,申请了2项国家发明专利。
The project uses energy-saving and environmental protection patented technology to produce bearing steel GCr15 wire 80,000 t, the physical quality of products reached the leading domestic level, a total of 60 million yuan for enterprises and social creation effect. According to the characteristics of bearing steel GCr15, combined with the existing equipment status of E Steel, we researched and developed the bearing steel GCr15 wire “80% hot metal + full oxygen blowing without scrap smelting +” smelting + “finish rolling surplus control + three stages Control cold ”production process. The technology is a national initiative, applied for two national invention patents.
