西(林)钢三座高炉配备的十座热风炉全部是球式热风炉,为了满足高炉对风温的需要,热风炉应进行不定期倒球,以确保热风炉能够实现快速烧炉。倒球热风炉点火及烘炉出现的问题:⑴热风炉点不着火,高炉煤气外溢,导致操作人员煤气中毒;⑵利用长期休风检修的机会,对热风炉进行同步倒球, West (Lin) Steel blast furnace equipped with three blast furnace are all hot-blast stove, in order to meet the needs of the blast furnace temperature, stove should be carried out from time to time rolling to ensure that stoves can achieve rapid furnace. Problems of ignition and oven of hot-air pouring furnace: (1) Hot-blast furnace does not catch fire and blast furnace gas overflows, resulting in gas poisoning of operators; (2) Making use of the opportunity of long-
