What are the factors that affect the quality of calcined petroleum coke

Release date:2016-09-26 Author: Click:

According to the different sulfur content, can be divided into high sulfur (sulfur content above 3%) and low sulphur coke (following sulfur content 3%). Low sulfur coke can be used as anode paste and prebaked anode for aluminum and graphite electrode used for the use of steel plants. The high sulfur coke (sulfur content less than 0.5%) can be used to production of graphite electrode and carburetant. The general quality of low sulfur coke (sulfur content less than 1.5%) are commonly used in the production of prebaked anode. And the low quality of petroleum coke is mainly used in industrial silicon smelting and production of anode paste. High sulfur coke is commonly used as a cement plant and fuel for power plants.

Calcined petroleum coke (Petroleum Coke Calcined):

In the steel with graphite electrode or aluminum and magnesium by anode paste (melting electrode), in order to make the petroleum coke (coke) to meet the requirements, must be carried out on coke calcination. The calcination temperature in 1300 degrees Celsius, the purpose is to try to get rid of volatile petroleum coke. This can reduce the content of hydrogen petroleum coke products again, the degree of graphitization of petroleum coke increased, thereby improving the graphite electrode of high temperature strength and heat resistance, and improved the conductivity of the graphite electrode. The calcined coke is mainly used in the production of graphite electrode, carbon paste, carborundum, food grade phosphate industry, metallurgical industry and calcium carbide, one of the most widely is the application of graphite electrode. Coke without calcination can be directly used for production of calcium carbide carbide material, silicon carbide and boron carbide as abrasive materials. Also can be directly used as coke or blast furnace wall lining brick of blast furnace in metallurgical industry, but also can be used for casting Art with dense coke and so on.
