Petroleum coke product introduction
Low sulfur, high quality cooked coke, such as needle coke, is mainly used for manufacturing ultra-high power graphite electrode and some special carbon products; Needle coke is an important material for developing new steelmaking technology in steelmaking industry.
Medium sulfur, common cooked coke, used in large quantities in aluminum smelting.
High sulfur, common coke, is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting fuel.
With the rapid development of cement, electrolytic silver, steel and thermoelectric industries in China, the demand for low-sulfur petroleum coke increases sharply. However, with the increasingly strict environmental protection policies, the use of high-sulfur petroleum coke is greatly restricted. Therefore, China's future petroleum coke market will face the situation of low sulfur petroleum coke in short supply and high sulfur petroleum coke excess.
Most of the petroleum coke produced in China is low-sulfur coke, which is used to make aluminum and graphite.
It is also mainly used for making carbon products, such as graphite electrode and anode arc, for steelmaking, non-ferrous metal and aluminum smelting. Making silicon carbide products, such as various grinding wheels, sand leather, sand paper, etc.; To produce commercial calcium carbide for synthetic fiber, acetylene and other products; It can also be used as fuel, but when it is used as fuel, it needs graded impact grinding for ultrafine grinding. It can only be burned after the coke powder is made by JZC-1250 equipment. Coke powder is mainly used in some glass factories, coal water slurry factories and so on.
Index of calcined petroleum coke
Application: High carbon carburizer is an auxiliary material for increasing carbon content in steelmaking process. Particle size can be processed according to user requirements.

Calcined petroleum coke is used for graphite electrodesThe main uses of petroleum coke are pre-baked anode and anode paste for electrolytic aluminum, carbon production of carbonizing agent, graphite electrode, smelting industrial silicon and fuel, etc

Ordinary power graphite electrodeBefore graphitization, the product can be put into the impregnating cylinder for infiltration, so as to increase the density of the electrode, and then roasted (especially special graphite products) in the furnace. The last process is machine processing, turning the outer diameter of the electrode and the thread of the interface.
Impregnated graphite electrodeThe products of the company are all made of petroleum coke with high quality after forging as raw material, the petroleum coke is broken and ground, screened into different size particles, and then mixed with carbonizable adhesive to make it into a thermoplastic material, and then extruded into the required cube, and roasted in the furnace to make the adhesive carbonized
