高炉炉底排铅是合理利用矿产资源,增加生产,节约能耗,保护环境和提高经济效益的一个简而易行的好办法。今将这方面的情况与认识介绍于下,以供类似条件高炉作参考。一、炉底排铅是一举多得的可行措施我国部份铁矿和锰矿资源中伴有铅、锌、银等有色金属。有些铁矿含铅量都超过了高炉冶炼的要求,一般在0.2—1.0%之间。某些锰矿的含铅量还高些,含铅量都在2.0%左右。这类含铅较高的矿石,一般不宜直接入炉冶炼,困而致使这部份矿产资源得不到及时的开发和合理利用。其原因是 Blast furnace bottom row of lead is the rational use of mineral resources, increase production, energy conservation, environmental protection and improve economic efficiency of a simple and easy way. The present situation and understanding in this regard are introduced below, for similar conditions for blast furnace for reference. First, the bottom of the row of lead is feasible measures in one fell swoop China’s part of the iron ore and manganese resources associated with lead, zinc, silver and other non-ferrous metals. Some iron ore lead content exceeds the requirements of blast furnace smelting, generally between 0.2-1.0%. Some manganese ore lead content is still higher, lead content is about 2.0%. Such high-lead ore, the general should not be directly into the furnace smelting, sleepy and lead to this part of the mineral resources can not be timely development and rational use. The reason is
