摘要
在微合金化钢板生产中,铸坯及钢板表面横裂纹缺陷一直是困扰钢铁工业的世界性技术难题。邯钢与钢铁研究总院联合攻关,以邯宝炼钢厂板坯连铸机为依托,成功开发了倒角铸坯冷却系统精确控制、连铸机辊缝及外弧线快速调整等重要创新技术,实现了倒角结晶器大规模工业化稳定生产,对推动微合金化钢在国内的高效化、低成本生产具有重要意义。
In the process of producing microalloyed steel plate, these defects of the transverse crack are often appeared in slab and steel plate surface, it is always a worldwide technical problems and plague the whole steel industry, Hansteel and Iron and Steel Research Institute intend to research the key problems together, re- lying on the slab caster of the steel plant in Hanbao steel, developed a series of important technical innovation successfully, for instance, in the process of producing chamfering slab, the precise control technology for the cooling system, the technology for adjusting quickly the roll gaps and outswinger of the caster, etc, Realized stable production of industrialization, in china, It has important significance in terms of production high - effi- ciency and inexpensive production.
