Anode Block

Anode block
The anode block is used in the 18 groove of the electrolytic cell. In the life cycle of anode carbon block, with anode were gradually consumed, anode mechanism driven carbon anode piece of the fall to ensure the electrolyzer stable configurations. When used for a certain period of time, the carbon block has become very thin (about L3 ~ 18cm), in order to prevent the molten electrolyte for the anode steel claw must replace the new anode carbon block group. These residual carbon blocks are called as residues. High calorific value, dry without water, 1 tons equivalent to 1.5 tons of metallurgical coke. Maximal residual anode carbon block is generally in the range of 15% to 25%.
Residual very for a long time and electrolyte contact containing higher electrolyte components, such as aluminum, sodium, potassium, calcium, magnesium, lithium, fluorine composition, appearance is often accompanied by electrolyte formed by crust. Residue after cleaning can be used in the production process of anode materials. From the electrolytic tank to replace the residual polar group, to remove residual surface electrolyte shell, and then use the residual anode pressure disengaging machine or manual remnant pole and the guide rod is separated. With a hammer or press off and make the steel claw separating ring on iron claw. Residual anode on the residual electrolyte should be carefully cleaned, carbon product conductivity and oxidation activity of these electrolytes because, due to the gas permeation and gasification, the volume density of the residual anode decreased. After crushing and screening, the residues are divided into different sizes, which are used as a kind of aggregate to be added when the anode carbon block or anode paste is produced. Residues can also be used as fuel for smelting.

Anode block application
Generally speaking, the tank after stripping and cleaning the anode mud, can be melted and cast anode. Some lower pole can also be used for other purposes, for example, copper sunset very as cold material added to the converter, can also be used as a raw material for manufacture of copper sulfate; nickel residual anode can be used for manufacturing of nickel ions in the electrolyte.
