Description
Cathode carbon brick is one of the important materials in aluminum electrolysis production. It is a kind of carbon material made of high quality anthracite, coke, graphite and other raw materials, which is used in the cathode part of aluminum electrolyzer. The main function of cathode carbon bricks is to collect aluminum metal and participate in the aluminum electrolysis reaction, and its performance directly affects the efficiency and quality of aluminum electrolysis cells.
Features
Conductivity
Cathode bricks have good electrical conductivity, which ensures efficient passage of current.
Thermal shock resistance
The cathode carbon bricks have good thermal shock resistance, which can quickly adapt to the temperature change during the high temperature and cooling process to minimize the thermal shock damage.
Erosion resistance
The cathode carbon bricks can resist the erosion of molten metal and electrolyte, and are not easy to be damaged by erosion.
Mechanical strength
The cathode carbon bricks have sufficient mechanical strength to withstand the scouring and corrosion of molten metal.
Thermal expansion
The coefficient of thermal expansion of the cathode carbon bricks is similar to that of the side charcoal blocks and coke bedding, which enables them to maintain good integrity under high-temperature operating conditions.
Airtightness
The gas tightness of cathode carbon bricks is good, which can prevent gas from passing through the electrode carbon and affecting the redox balance of the electrolyzer.
Application
Aluminum Electrolysis Production
Cathode carbon bricks are one of the main materials used to collect aluminum metal in aluminum electrolysis cells, and their performance directly affects the efficiency and quality of aluminum electrolysis cells. The excellent performance of cathode carbon bricks can ensure the aluminum electrolysis reaction and improve the purity and quality of aluminum.
Other metal smelting
Cathode carbon bricks can also be applied in other metal smelting processes, such as the electrolytic production of copper, zinc and other metals, as well as the refining process of steel, cast iron and other metals, for the collection of metal ions and gases.
Other fields
The materials and properties of cathode carbon bricks can also be applied in other fields, such as electrodes, electrolysis tanks, filters and other equipment in chemical, electric power, environmental protection and other fields, for cleaning and reusing used electrode materials.
