在包钢设计院、国家建委建材院的大力支持和协助下,我厂对二号高炉的煤气系统和热风系统进行了全套设备改造,大胆采用了球式热风炉和布袋除尘器两项新工艺。经过改造后使用,布袋除尘器净化煤气的效果很好,净煤气含尘量达到10毫克/立米以下,完全满足了球式热风炉燃烧煤气含尘量在20毫克/立米以下的要求,球式热风炉风温达到1050℃,为高炉增铁节焦创造了有利条件。设备改造后的七五年全厂生产生铁13020吨,超国家计划2020吨,成本也有所降低,各项主要经济技术指标的完成情况也有所改进。 1976年以来,革命和生产不断发展。九月份生
With the strong support and assistance from Baotou Steel Design Institute and State Construction Committee Building Materials Institute, our factory transformed the complete set of equipment of No.2 blast furnace gas system and hot blast system, boldly adopted two new processes of ball-type hot blast stove and bag filter . After the transformation and use of the bag filter to purify the gas well, the net gas dust content of 10 mg / cubic meters or less, fully meet the ball hot blast furnace gas dust content of 20 mg / cubic meters below the requirements of the ball Stove temperature reached 1050 ℃, for the blast furnace to increase the focus of the iron created favorable conditions. After the transformation of the equipment, the whole factory will produce 13,020 tons of pig iron in 775 years and exceed the national plan by 2020 tons. The cost has also been reduced. The completion of all the major economic and technical indicators has also been improved. Since 1976, the revolution and production have been continuously developing. Born in September
