Calcined petroleum coke manufacturers teach you how to use CPC to smelt aluminum

Calcined petroleum coke manufacturers produce calcined petroleum coke for aluminum production, graphite electrodes, carbon paste products, corundum, food-grade phosphorus industry, metallurgical industry and calcium carbide, among which graphite electrodes are the most widely used. Today, calcined petroleum coke manufacturers teach you how to use CPC to smelt aluminum.

Calcined petroleum coke is a carbonaceous material obtained by heating and dry distilling refinery waste at high temperature. Calcined petroleum coke contains a large amount of carbon and a small amount of impurities, and is an efficient fuel and reducing agent. Calcined petroleum coke manufacturers strictly control quality indicators because it is crucial to the effect of aluminum refining. When making aluminum, petroleum coke must undergo an essential link-calcination. The calcination temperature is generally around 1300℃, the purpose is to remove the volatile matter of petroleum coke as much as possible. This can reduce the hydrogen content of petroleum coke remanufactured products, improve the graphitization degree of petroleum coke, thereby improving the high temperature strength and heat resistance of graphite electrodes, and improving the conductivity of graphite electrodes.

The main role of calcined petroleum coke in aluminum refining is to improve the electrolysis efficiency in aluminum electrolytic cells. The process of electrolysis of aluminum is carried out at high temperature, and the aluminum ions need to be reduced to pure aluminum through the current in the electrolytic cell. Calcined petroleum coke can be used as a reducing agent to participate in this process and help reduce aluminum ions. Compared with other reducing agents, calcined petroleum coke has higher reducing performance, which can improve electrolysis efficiency and reduce electrolysis energy consumption.

In addition, calcined petroleum coke also helps to reduce the accumulation of oxides in the electrolytic cell, which can reduce the resistance and current density of the electrolytic cell and further improve the electrolysis efficiency. At the same time, impurities such as sulfur and nitrogen in calcined petroleum coke can react with alumina to generate solid nitrides and sulfides in the electrolytic cell, which can protect the refractory materials on the inner wall of the aluminum electrolytic cell and reduce the erosion of the refractory materials.

In short, calcined petroleum coke manufacturers often use calcined petroleum coke as a raw material for aluminum electrolysis because it plays an important role in the aluminum refining process. It can improve the efficiency of aluminum electrolysis and reduce the power consumption required for electrolysis, and can protect the refractory materials on the inner wall of the electrolytic cell. The quality indicators of calcined petroleum coke are crucial to the effect of aluminum refining. Calcined petroleum coke manufacturers need to strictly control the temperature, time and composition of raw materials during the preparation process.
