What is electrode paste?

Electrode paste is defined as a consumable conductive material used in the production of calcium carbide, ferroalloys, and yellow phosphorus in the submerged arc furnace.

The electrode paste is baked used for the heat source of an electric furnace to form a self-baking electrode. The self-baking electrode is a metal shell filled with electrode paste. When the furnace is hot and the current passes through the electrode, heat is generated, and the electrode paste is baked to become a conductive electrode.

Ingredients: Anthracite, metallurgical coke, pitch coke, graphite, and additives.

Properties:

Electrical conductivity: It promotes the efficient transmission of electrical energy to generate high temperatures to melt scrap metal.
Thermal stability: Its ability to withstand extreme temperatures (up to 3000°C) inside the EAF without degradation.
Mechanical strength: The electrode paste provides structural integrity to the electrode, ensuring that it can withstand mechanical stress and vibration during operation.

Uses of electrode paste in smelting:

Self-baking electrode paste is used for the main raw material to burn into electrodes. In the submerged arc furnace, the quality of the electrode directly affects the product production. Electrodes play the role of conducting current and converting electrical energy into heat energy in electric furnaces.

In industrial production, current is input into the furnace through electrodes to generate arcs. The arc energy is mainly used to release heat and produce products through high-temperature smelting.

Conclusion:

With the development of ferroalloy and calcium carbide industries, the demand for electrode paste products is also increasing. As an important raw material used in the production of electric furnaces, its mechanical strength and high temperature resistance determine the high efficiency of production.
