在首都钢铁公司 公司对初轧厂钢锭入炉温度组织初轧厂、运输部等单位共同攻关,提出浇铸后提前动车、少拉勤跑、减少钢锭温降的措施。试验结果是钢锭温度最高达827℃,平均提高14℃,使初轧工序能耗降低2kg/t,同时产量也增加了。另外,通过合理组织生产,使热锭率提高了1.7％,今年少吃冷钢锭1.4万吨,可降低工序能耗0.5kg/t。1985年以来,均热炉22个炉坑推广了浇注可塑料,占全部炉坑的91.67％,应用硅酸铝纤维炉坑6个,节约燃料3％。 在烧结厂,首先对烧结点火器作了改造。原来烧结点火器采用的是高炉膛、拱顶、低压涡流烧
Capital Iron and Steel Company in the early rolling plant ingot furnace temperature of the organization of early rolling mill, the Ministry of Transport and other units jointly tackling the issue put forward in advance after the motor car after casting, run less frequently run to reduce the temperature drop measures. The test results show that the ingot temperature is up to 827 ° C and the average increase is 14 ° C, reducing the energy consumption of the initial rolling process by 2kg / t while increasing the yield. In addition, by reasonably organizing the production, the hot-rolled ingot rate increased by 1.7%. This year, the consumption of cold-rolled ingot of 14,000t can reduce the energy consumption of the process by 0.5kg / t. Since 1985, 22 pits in a soaking furnace have been popularized with castables, accounting for 91.67% of all pits and 6 using aluminum silicate fiber pits to save 3% of fuel. In the sintering plant, the first to make a renovation of the sintering igniter. The original sintered igniter is used blast furnace, vault, low pressure eddy current
