从炉缸问题调查着手,通过大量理论计算指出了炉缸气隙的危害,并结合现场调查、施工和生产实践,分析了炉缸产生气隙的各种因素,最终提出了从设计、施工到高炉操作的这些炉缸长寿链上各关键环节系统防止炉缸气隙的有效措施,为高炉炉缸实现无气隙化操作、实现炉缸长寿提供了全面的解决方案。研究指出夹壳式冷却方式、热水烘炉、防止炉缸漏水是减小炉缸气隙最有效的措施。
Gas gap was the biggest threat to BF hearth long campaign life. Through academic calculations and field investigations, the influencing factors to cause gas gap in hearth area was analyzed. As the results, the effective measures involving design, construction and operation were proposed to avoid gas gap for long campaign life of BF hearth, and the solutions were provided to achieve non-gas gap operation and long hearth life. Jacket cooling, using hot water during furnace drying process and leak prevention were found to be the most effective measures of gas gap prevention.
