介绍了新日铁自主创新的6项连铸技术,重点有:中间包等离子加热、多模式电磁搅拌、铸坯面压下、复合钢板坯连铸、超厚钢板新型连铸机和薄带铸轧等。分析认为,目前新日铁的传统连铸技术领先于世界,下一步发展目标是薄带连铸技术的推广与普及。指出学习和借鉴新日铁自主创新的连铸技术,对低成本制造顶级钢铁产品会有一定的促进作用。
Six new continuous casting technologies of Nippon Steel’s independent innovation are introduced, including: tundish plasma heating, multi-mode electromagnetic stirring, slab face reduction, composite steel slab continuous casting, new type thick steel plate continuous casting machine and strip casting Rolling and so on. Analysis, the current Nippon Steel continuous casting technology ahead of the world, the next step is the development of thin-strip casting technology to promote and popularize. It is pointed out that studying and learning from the continuous casting technology of Nippon Steel’s independent innovation will promote the production of top-grade steel products at low cost.
