As a Carburizer
Calcined petroleum coke is commonly used as a carburizing agent in steel smelting to supplement the carbon content in molten iron or steel. During the steelmaking process, prolonged operations such as smelting and heat preservation can lead to carbon loss. The addition of calcined petroleum coke allows for precise control of the carbon content in steel, meeting the performance requirements of different steel grades. For example, in the production of high-carbon steel, calcined petroleum coke can effectively increase the carbon content of molten steel, enhancing its strength and hardness.
improving Steel Performance
The high carbon, low sulfur, and low ash characteristics of calcined petroleum coke make it an ideal carbon additive. It helps improve the strength, hardness, and corrosion resistance of steel while reducing the impact of impurities on steel quality. For instance, in the production of special steels such as wear-resistant steel and weather-resistant steel, the application of calcined petroleum coke can significantly enhance the overall performance of the steel.
Raw Material for Graphite Electrodes
Some calcined petroleum coke is further processed to produce graphite electrodes. Graphite electrodes are essential consumables in electric arc furnace steelmaking, and their quality and performance directly affect steelmaking efficiency and steel quality. After graphitization treatment, calcined petroleum coke can be used to manufacture high-power and ultra-high-power graphite electrodes, meeting the stringent requirements of modern electric arc furnace steelmaking.
Post-Furnace Adjustment
In the steel production process, calcined petroleum coke can also be used for post-furnace adjustments. For example, when the carbon content or performance indicators of steel do not meet requirements, the addition of calcined petroleum coke allows for fine-tuning to ensure the stable quality of the final product.
In summary, the application of calcined petroleum coke in the steel market primarily focuses on carburization, performance enhancement, and electrode manufacturing, playing a critical role in improving steel quality and production efficiency.
