Embodiment 1
[0023] A new anode material for electrolysis of nonferrous metals. The anode material is composed of a low-silver lead-cobalt-tin-calcium-antimony multi-element alloy anode, and the weight percentage of each component is: silver 0.15%, cobalt 0.06%, tin 0.2%, calcium 0.06% , antimony 0.3%, the balance is lead. The lead plate is processed into a 220mm×140mm×8mm sample.
[0024] The manufacturing method steps are as follows:
[0025] A. The lead block with a purity of 99.9% is melted at 340°C. After melting, the temperature is rapidly raised to 900-1000°C, and silver-cobalt and tin-cobalt intermediate alloys are added respectively, and stirred evenly. After melting, some lead is added. After the temperature is 550°C, Add lead-calcium master alloy and antimony block and the balance of lead.
[0026] B. After fully stirring the obtained lead alloy liquid for 30 minutes, let it stand for 5 minutes, scoop out the slag, pour it, and transfer it to a rapid water cooling device to ob...
