凌源钢铁公司烧结厂为了改善保国铁精矿的焙烧性能,提高球团矿的冷强度,选用化工厂生产硼砂的副产物硼泥为添加剂,在试验室及8m~2竖炉上进行了工业性焙烧试验,并在凌钢100和300m~3高炉上进行了冶炼试验研究,取得了良好的效果。试验室和竖炉焙烧试验结果表明,采用一定数量的硼泥做添加剂生产球团矿,可以显著提高球团矿的冷强度,不同程度地改善 In order to improve the roasting performance of Baoguo Iron Concentrate and improve the cold strength of pellets, Boron Sludge, a byproduct of borax production in chemical plant, was used as additive in the laboratory and 8m ~ 2 shaft furnace Industrial roasting test, and carried out smelting test on 100 and 300m ~ 3 blast furnaces of Lingang Iron and Steel Co., Ltd., and achieved good results. The roasting test results of laboratory and shaft furnaces indicate that using a certain amount of boron sludge as additive to produce pellets can significantly improve the cold strength of pellets and improve to some extent
