八钢2500m~3高炉复风实践

八钢2500m3高炉实现了低焦炭强度下大高炉冶炼,但高炉休风后炉况的恢复困难,主要是炉热不足、恢复时间长。为了确保炉况快速安全恢复,对快速复风操作的可行性进行了探索和实践,铁水质量和产量得到显著提高。

Reblowing Practice of Bagang 2500m3 BF

The melting operation with low coke ratio of 2500m3 furnace in Bagan was done, but be- cause of inadequate heat and long recover time after blow - off coke blast furnace operated difficultly, In order to let the furnace operation restore rapidly and safely, some feasible exploration and practices were taken to fulfill rapid reblow and some progress has been made. As a result, the restoring period becomes short, furnace heat is enough during reblowing, the hot metal quality and output increase considerably.
