Restoration Practice of 3200 m^(3) Blast Furnace in Laisteel

莱钢3200 m^(3)高炉受原燃料变化、定修及设备故障等一系列因素影响,炉况顺行变差、冶强降低。后期通过对“四大制度”调整,重新分布两股气流,活跃炉缸,使高炉恢复正常。通过对此次恢复过程进行经验总结并对在恢复过程中存在问题进行反思。

Under the influence of a series of factors,such as the change of raw fuel,fixed repair and equipment failure,the furnace condition and smelting strength of 3200 m^(3) blast furnace in Laisteel.Later,by adjusting the"four major systems",redistributing the two air streams and activating the furnace cylinder,the blast furnace returned to normal.By summarizing the experience of the recovery process,and reflecting on the problems in the recovery process.
