武汉冶金建筑研究所与本溪钢铁公司共同在5号高炉(2000m~3)地得式外燃热风炉进行冷风均匀配气装置工业试验。1987年6～10月四座热风炉试验结果与前17个月操作结果比较,平均风温提高23℃左右,可节焦3.5kg/t铁,增产约1.15％,废气温度降低9℃左右,热风炉热效率提高约0.65％。全年经济效益可达154万元以上。冷模型的冷风均匀率由62.5％增至75.2％。 1988年8月5日冶金部科技司在本钢召开了此项技术的鉴定会,有来自企业、研究、设计、学院等18个单位42名代表到会,
Wuhan Metallurgical Construction Institute and Benxi Iron and Steel Company in the No. 5 blast furnace (2000m ~ 3) to type external combustion stove for cold air even gas distribution device industrial test. The results of the four hot blast stoves from June to October 1987 were compared with those of the first 17 months. The average air temperature was raised by about 23 ℃, and 3.5kg / t iron was coke-thrusted. The yield was increased by 1.15% and the exhaust gas temperature was reduced by about 9 ℃. Furnace thermal efficiency increased by about 0.65%. Annual economic benefits up to 1.54 million yuan. The cold uniformity of the cold model increased from 62.5% to 75.2%. August 5, 1988 Ministry of Science and Technology Metallurgical Division in Benguang held the appraisal of this technology, there are 42 representatives from enterprises, research, design, colleges and other units to attend the meeting,
