Packing: Ton bag
Origin: China
Min Order Quantity: 100 MT
Supply Capability: 5000 Tons/Month

Foundry coke is mainly used in iron foundries to produce molten iron. It is the finest source of fuel in a cupola furnace. It is also used for melting iron as it is used as a carbon source for the melted product. It is used for casting automobile parts, casting machinery, and is used for insulation.
The usage of Foundry Coke in the cupola furnace is projected to be the key factor driving the Foundry Coke market forward.

C. Semi-Coke

Other Name: Gas Coke
Size: 0-3 mm, 0-5 mm, 1-3 mm, 1-5 mm, or 3-8 mm
Packing: In Bulk / Ton bag
Origin: China
Min Order Quantity: 100 MT
Supply Capability: 5000 Tons/Month

Semi-coke is a solid carbonaceous material produced by carbonizing coal at a low temperature, usually below 700 degrees Celsius. Semi-coke is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur, and Low phosphorus. Semi-coke can be used as a substitute for Met Coke. It is wildly applied to the chemical industry, metallurgical industry, and gas-making industry nowadays. It is known for its ability to adsorb contaminants and is used in environmental remediation applications also.

Application:

  • Reducing electricity consumption in Ferro Alloy Production Significantly.
  • Reducing agent for gasification industry specially carbide manufacturing
  • Reducing input cost in EAF as a substitute of Met Coke
