Application Of Pet-coke
Petroleum coke (Pet-coke for short) is a product of crude oil that is distilled to separate light and heavy oils, and then the heavy oil is converted into a product through the process of thermal cracking. From the appearance, the coke is black lumps with irregular shapes and different sizes. (Or particles), with metallic luster, coke particles have a porous structure, the main element is carbon, occupying more than 80%, containing 1.5%-8% hydrogen, and the rest are oxygen, nitrogen, sulfur and metal elements.
Depending on its quality, Pet-coke can be used for graphite production, smelting and chemical industries.
Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high power graphite electrodes and certain special carbon products; needle coke is an important material for the development of new electric furnace steelmaking technology in the steelmaking industry.
Medium-sulfur, ordinary cooked coke is used in aluminum smelting.
High-sulfur, ordinary green coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., and also as a fuel for metal casting.
Most of the Pet-coke produced in China is low-sulfur coke, which is mainly used for aluminum smelting and graphite production. It is also mainly used to make carbon products, such as graphite electrodes and anode arcs, for steelmaking, non-ferrous metals, and aluminum smelting; to make silicon carbide products, such as various grinding wheels, sand skins, sandpaper, etc.; to make commercial calcium carbide for Production of synthetic fibers, acetylene and other products; It can also be used as fuel, mainly some glass factories, coal water slurry factories and so on.
Pet-coke grinding equipment recommendation: Shanghai ZENITH new generation MTW series trapezium mill. This series mill is the latest grinding equipment researched and developed by our company’s experts based on years’ experiences of industrial mill design and listened to thousands of users at home and abroad on the basis of MTM series industrial mills. This mill developed multiple patented technology property rights (such as bevel gear integral transmission, internal thin oil lubrication system, arc-shaped air duct, etc.). The launch of this product indicates that our company has reached the international first-class level in the design and production of industrial mills.
