Wholesale Calcined Petroleum Coke in China tells you that honeycomb coke has a relatively uniform distribution of pores, apparent honeycomb structure, and good physical and mechanical properties.

In China, wholesale calcined petroleum coke refers to the process of heating the raw petcoke to a high temperature to remove volatile compounds and impurities, resulting in a more pure and dense carbon material. Calcined petroleum coke is widely used in various industries due to its high carbon content and excellent properties.

Aluminum Industry: Calcined petroleum coke is used as a carbon source in the aluminum smelting process. It provides high-purity carbon and has good conductivity and thermal conductivity, which helps improve the smelting efficiency and quality of aluminum.

Steel Industry: Calcined petroleum coke is an important carbon additive in the steel production process. It is used to reduce the content of metal oxides, improve desulfurization capacity of slag, and increase the flowability of slag. It also provides sufficient carbon content to ensure the quality and performance of steel.

Graphite Electrode Manufacturing: Calcined petroleum coke is used as the primary raw material in the production of graphite electrodes. Graphite electrodes are critical conductive materials used in electric arc furnaces for melting metals and alloys. Calcined petroleum coke provides high-purity carbon with low resistance and high conductivity, ensuring the efficient operation of graphite electrodes.

Energy Electrode Manufacturing: Calcined petroleum coke is also used in the manufacturing of energy electrodes, such as fuel cells and lithium-ion batteries. It provides high-purity carbon with high energy density and cyclic stability, contributing to the improved performance and lifespan of energy batteries.

The shape of China’s calcined petroleum coke is generally granular or lumpy. According to different needs, it can be processed into products of various particle sizes and shapes, such as 0-1mm powder, 1-5mm granules, or large blocks.

The physical properties of calcined petroleum coke are as follows:

High carbon content: The carbon content of calcined petroleum coke is usually above 90%, and some even reach above 98%.

High density: The density of calcined petroleum coke is relatively high, generally between 2.0-2.2 g/cm³. 

Strong wear resistance: Due to the close packing between petroleum coke particles, it has high wear resistance, which can reduce wear and chipping.

High thermal conductivity: Petroleum coke has high thermal conductivity and can conduct heat quickly.

High electrical conductivity: Petroleum coke has good electrical conductivity properties and is suitable for providing current during the electrolysis process.
