通过对本钢转炉生产特殊钢工艺的开发与生产实践,探索出合适的转炉生产特殊钢工艺路径,采用铁水预处理、转炉冶炼、AHF/LF/RH精炼、模铸、热送与800/650连轧工艺技术。开发的特殊钢品种,具有钢水纯净度高,夹杂物含量少,炉批量大,偏析和残余元素少的特点从而提高了钢材的机械性能;实践证明该工艺合理可行,具备大生产条件,可以投入生产。
Through the development and production practice of the special steel production process in Benxi Iron and Steel Co., Ltd., we find out the suitable technological route of special steel production by converter, using hot metal pretreatment, converter smelting, AHF / LF / RH refining, Rolling technology. Development of special steel varieties, with high purity of steel, inclusions less, furnace mass, segregation and fewer residual elements to improve the mechanical properties of steel; Practice has proved that the process is reasonable and feasible, with large production conditions, you can invest produce.
