从5000 m3级高炉炉壳用钢研发与生产的角度进行了重点研究与分析,在现场试制过程中重点从成分设计、工艺路线选择、工序质量控制上进行了详细论证,通过采取精炼双联(LF+VD)工艺、严格地控制硫、磷、氮、氢及微合金化处理,最终成功试制出板坯低倍质量良好,各项工艺力学性能稳定的5 000 m3级高炉炉壳用钢,此举为微合金钢的宽厚板生产奠定了一定的理论与实践基础。 The key research and analysis are made from the perspective of R & D and production of 5000 m3 blast furnace shell steel. The key points of the trial production process are the ingredient design, process route selection and process quality control. In this paper, LF + VD) process, Sulfur, Phosphorus, Nitrogen, Hydrogen and micro-alloying treatment are strictly controlled. Finally, the slab steel with a good low slab quality and various mechanical and mechanical properties is successfully manufactured. This measure has laid a certain theoretical and practical basis for the production of micro-alloyed steel plate.
