格洛韦尔铅厂鼓风炉产出的铅含有铜和硫,在1200℃温度下由鼓风炉流入前床,然后用衬有耐火材料的包子运到具有300吨能力的钢锅中,在此冷却,铅中夹带的大部铜和硫析出形成渣子,即所谓粗铜渣,在500℃左右用勺子撇出。该厂年产粗铜渣10,000吨,平均含Pb74％、Cu13％、S8％。 The lead from the Rockwell blast furnace blast furnace contains copper and sulfur and flows from the blast furnace into the forehearth at a temperature of 1200 ° C. It is then transported to a steel pan with a capacity of 300 tons using a lined bump, where it is cooled, Most of the lead entrained in the copper and sulfur precipitation to form a slag, the so-called blister copper slag, about 500 ℃ with a spoon sketched out. The plant annual output of 10,000 tons of coarse copper slag, with an average of 74% Pb, Cu13%, S8%.
