The main benefits of using calcined petroleum coke and graphitized petroleum coke in foundries are as follows:

1. Both calcined petroleum coke and graphitized petroleum coke are high-purity carbon materials with high calorific value, low ash content, low volatile matter and low sulfur content, so they can well guarantee the quality of casting products.

2. Calcined petroleum coke and graphitized petroleum coke have good chemical stability, are not easily oxidized, and can well resist oxidation, corrosion and high temperature erosion.

3. Calcined petroleum coke and graphitized petroleum coke have uniform particle shape and size, large specific surface area, strong adsorption performance, can be well mixed with other batch materials, and ensure the uniform distribution of carbon in the casting.

4. Calcined petroleum coke and graphitized petroleum coke have high electrical conductivity and can conduct electricity well, which is very important for electrothermal treatment in the casting process.

There are many other industries and fields that use calcined petroleum coke and graphitized petroleum coke. The following are some typical applications:

1. Iron and steel industry: Calcined petroleum coke and graphitized petroleum coke are the main reducing agent and carbon source in the steelmaking process. They can well reduce the oxide content in the charge and promote the reduction reaction, thereby improving the efficiency of steelmaking and the quality of steel.

2. Chemical industry: calcined petroleum coke and graphitized petroleum coke can be used as catalyst carrier or adsorbent. Their high porosity, large specific surface area and good adsorption performance can well catalyze or adsorb substances in chemical reactions, improving reaction rate and efficiency.

3. Coating industry: Calcined petroleum coke and graphitized petroleum coke are used as fillers or thickeners in coatings. They can improve the hardness, gloss and corrosion resistance of coatings, while reducing the cost of coatings.

4. Automobile industry: Calcined petroleum coke and graphitized petroleum coke can be used to make carbon fiber and its composite materials, and are used to manufacture high-strength and lightweight auto parts, such as body and chassis.
