摘要
首钢2号高炉在空料线降料面前保持炉况顺稳,降料面过程中使用高顶压、大风量,利用耗风量和煤气成分判断料面深度,随料层厚度及时降低压差,严密监视铜冷却壁温度变化,延长回收煤气时间,实现了降料面过程的快速、安全、环保。
Before dropping the stockline in case of empty stock, the furnace operation status must be kept stable. During dropping, the furnace shall operate at high top pressure and great air blasting , judge the depth of stockline according to air consumption and gas composition. However it is also necessary to reduce differential pressure according to stock thickness and monitor temperature variation of the copper cooling stave in order to get longer gas recovery time and realize rapid, safe and environment friendly dropping.
