济钢三铁1^#高炉大修工艺设计

The Heavy Repair Process Design of No. 1 Blast Furnace of No.3 Ironmaking Plant in Jinan Iron and Steel Groun General Corporation

济钢三铁１＾＃高炉扩容大修工艺设计中采用了炉体，炉前技术，使高炉容积由１００ｍ＾３提高到１２８ｍ＾３，高炉，热风炉采用汽化冷却，高炉可节水９５％，节电９０％。热风炉节水，节电延长设备使用寿命，热风阀使用寿命大于一代炉龄。高炉煤气使用布袋除尘器，１２８ｍ＾３高炉每年节水１５４×１０＾４ｔ，节能折合标准煤２０００ｔ，使用顶燃式热风炉热内温度可达１０００－１３５０℃；微机监测稳定了操作，提高了效率。

Becouse the furnace body and the fumace front reforming techniques dre applied,the valume of blast furnace is increased from 100m￣3 to 128m￣3 and through application of vapouring cooling teehnique for blast furnace and hot blast store,the blast furnace can save of 95%water and 90%electricity. The service life of hot blast valve is greater than a generation campaign,because of extending sveice life of equipments. The blast furnace can save of water 154 × 10￣4 t and 2000t standdard coal tvery gear, because of application of bag filier.The hot blast temperature can up to 1000～1350℃ when hte top coinbusting hot blast fumace is applied. Since used of conputer monitoring control,the preduction effeciency of equipments are increased . The utilization factor of blast furnace in a mean of month is more than 2.35t/m￣3·d.
