Particle Size 1-5mm Synthetic Graphite For Brake Pads Lining Graphitized Calcined Petroleum Coke
Products Description
Petroleum coke is a black or dark gray hard solid petroleum product with metallic luster and is porous. Petroleum coke components are hydrocarbons, containing 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur and heavy metal compounds.
Application
According to the different sulfur content, it can be divided into
high-sulfur coke (sulfur content above 3%) and low-sulfur coke
(sulfur content below 3%).
Low-sulfur coke can be used as anode paste and prebaked anodes for
aluminum plants and as graphite electrodes for steel plants. Among
them, high-quality low-sulfur coke (sulfur content less than 0.5%)
can be used to produce graphite electrodes and carbon enhancers.
Normal quality low-sulfur coke (less than 1.5% sulfur) is often
used to produce prebaked anodes. Low-quality petroleum coke is
mainly used for smelting industrial silicon and producing anode
paste.
High-sulfur coke is generally used as a fuel in cement plants and
power plants.
In the case of graphite electrodes for steelmaking or anode pastes
(melting electrodes) for aluminum and magnesium production, in
order to adapt the petroleum coke (green coke) to the requirements,
the green coke must be calcined. The calcination temperature is
generally around 1300 ° C, the purpose is to remove the volatile
components of petroleum coke as much as possible. In this way, the
hydrogen content of the recycled petroleum coke can be reduced, and
the graphitization degree of the petroleum coke can be improved,
thereby improving the high temperature strength and heat resistance
of the graphite electrode, and improving the electrical
conductivity of the graphite electrode. Calcined coke is mainly
used in the production of graphite electrodes, carbon paste
products, diamond sand, food-grade phosphorus industry,
metallurgical industry and calcium carbide, among which graphite
electrodes are the most widely used.
