第四冶炼厂为处理铅鼓风炉副产品铅冰铜(铜铅锍),采取了图示流程在反射炉内进行富集铜的熔炼。炉料的配料比为:铅冰铜:炭酸钠:焦炭=100:6～8:1;炉料粒度控制为:铅冰铜<250毫米,焦炭<50毫米;熔炼是在炉膛面积为6.2米~2,熔池深575毫米,由炉顶进料,重油加热的反射炉内进行的。熔炼阶段炉膛高温区炉气温度为1300～1400℃,炉尾末端炉气温度为1050～1150℃,炉尾负压为4～6毫米水柱。熔炼的原料和产品的主要化学成分如下表所示:
Fourth smelter lead blast furnace by-products lead-matte (copper lead-lead-sulfonium), take the icon flow in the refiner furnace enrichment copper smelting. Charge material ratio of lead: lead matte: sodium carbonate: coke = 100: 6 ~ 8: 1; charge size control: lead matte copper <250 mm, coke <50 mm; melting is in the hearth area of 6.2 m ~ 2 , 575 mm deep in the pool, fed from the top of the furnace, and heated in a heavy oil furnace. In the melting stage, the temperature of the furnace gas is 1300-1400 DEG C, the temperature of the end of the furnace tail gas is 1050-1150 DEG C, and the negative pressure of the furnace tail is 4-6 mm water column. The main chemical components of the smelting raw materials and products are shown in the following table:
