Problems solved by technology

[0002] In the production process of electrolytic manganese, the anode plate is the main consumable part; the traditional anode plate is mostly made of lead, silver, tin, antimony, and arsenic five-element alloy, but it is easy to be corroded during use, which makes the transition of the conductive beam The row is easy to break and the amount of slag is high, which eventually leads to a short life of the anode plate and high power consumption during the production process

Abstract

The invention belongs to the technical field of metallurgy, and relates to an electrolytic manganese anode plate grid and a manufacturing method thereof. The electrolytic manganese anode grid comprises raw materials with the following mass fractions: 1.5% to 3.0% of tin, 0.3% to 1% of stibium, 0.05% to 1.5% of lanthanum, 0.05% to 1.5% of cerium, 0.05% to 2% of sodium, 0.05% to 2% of boron and thebalance of lead. According to the electrolytic manganese anode plate grid provided by the invention, by adding boron and sodium as well as lanthanum and cerium and by the cooperation with a smelting and casting process, the obtained anode plate grid is longer in service life, lower in resistance and lower in power consumption and can bring good economic benefits for an enterprise.
