结合攀钢集团有限公司提钒炼钢厂3号RH装备和工艺条件,在分析钢的质量要求的基础上,建立了合金结构钢、无缝钢管用钢、铁道用钢、高压容器用钢、锻件用钢等钢种的真空处理模式和工艺制度。生产实践表明,经3号RH处理后,出站钢水成分合格率达100%,成分精度控制在w(C)±0.02%、w(Si)±0.03%、w(Mn)±0.05%的综合合格率为88.6%,出站温度合格率达98.7%,脱氢效果良好,钢水洁净度得到明显改善,满足了高质量品种的要求。
On the basis of analyzing the quality requirements of steel on the No.3 RH equipment and technological conditions of the vanadium steelmaking plant of Panzhihua Iron and Steel Group Co., Ltd., the steel structure of the alloy structural steel, the seamless steel pipe, the steel for the railway, the steel for the high pressure vessel, Forgings with steel and other types of vacuum processing mode and process system. The production practice shows that after the 3rd RH treatment, the qualified rate of outflow molten steel reaches 100%, and the composition accuracy is controlled within ± 0.02% of w (C), ± 0.03% of w (Si) and ± 0.05% of w (Mn) The pass rate is 88.6%, out of the station temperature pass rate of 98.7%, dehydrogenation effect is good, the cleanliness of molten steel has been significantly improved to meet the requirements of high-quality varieties.
