Product Description of Carbon raiser
Carbon raiser is a big category that includes calcined petroleum coke(CPC), graphite petroleum coke(GPC), calcined anthracite coal(CAC),and natural graphite. Due to the high price of natural graphite, it is not suitable for steelmaking or casting, so calcined petroleum coke, graphite petroleum coke, and calcined coal are more suitable for the current steelmaking and casting process.
CAC: Calcined anthracite coal
Using anthracite as raw material, after 1300ºC dry distillation and calcination. Then reduce sulfur content, reduce volatile matter, and achieve the effect of increasing the carbon content of calcined anthracite coal.
CPC: Calcined petroleum coke
The raw material of Calcined petroleum coke is raw coke. Because of the high content of impurities in raw coke, it will contain a lot of impurities in liquid steel directly. Petroleum coke by 1200-1400ºC high-temperature calcination removes most of the water and volatile impurities. Carbon content is up to 98.5%. Calcined coke is an irregularly shaped carbon particle with metallic luster and more transparent carbon particle pores. The high quality of calcined petroleum coke mainly depends on the low sulfur content, which will eventually affect the quality of steel. If the sulfur content in calcined petroleum coke is too high, the produced steel will contain a lot of bubbles, which will affect the quality of steel. Calcined petroleum coke is the most suitable carbon raiser for steelmaking.
GPC: graphite petroleum coke
The raw material of graphite carbon additive is also coke, but the calcination temperature ratio is 3000, the carbon fixation degree is high, and Sulfur and phosphorus content is much lower than coal. Graphite petroleum coke is mainly used in nodular cast iron, with fast absorption, high carbon, and low sulfur characteristics. Graphitized petroleum coke is used in the production of high-quality steel, cast iron, and alloys. High-purity graphite petroleum coke is made from high-quality coke at temperatures of 2,500-3,500ºC. As a high purity carbon material, it has the characteristics of high fixed carbon content, low sulfur, low ash content, and high recovery rate.
Applications of Carbon Raiser
Metallurgical Coke Carbon additive manufacture,Steel making,Cement plants,Power plants,Vitrified tile manufacturers,clay bricks manufacturers,chemical industries,refractories and coal gasifier plants.
Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron.
It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.
