250 mm厚耐热钢F5水冷模铸的生产实践
Production Practice of 250 mm Thick Heat Resistant Steel F5 by Water-Cooled Die Casting

本研究通过优化生产工艺，控制冶炼操作，实现了采用“转炉 + LF精炼炉”流程生产出了低碳中合金钢；通过拥有自主知识产权的水冷模铸法浇铸，配合特殊加热、轧制工艺，生产出了250 mm规格大厚度保S2E2探伤的钢板；通过合理的切割工艺，实现了中合金钢用传统的火焰切割法切割。
By optimizing the production process and controlling the smelting operation, the low carbon me-dium alloy steel has been produced by the process of converter + LF refining furnace. By resorting to water-cooled die casting with independent intellectual property rights, 250 mm steel plate with large thickness and keeping S2E2 flaw detection was produced by combining with special heating and rolling process. Then, the traditional flame cutting method for medium alloy steel was realized through reasonable cutting technology.
