一.Features:
The coke in a cupola functions not only as a fuel but also, and more important, as a medium of heat transfer. The key factor affecting the efficiency of the molten metal heating-up is the surface combustion temperature of the coke. Thus, the reactivity of the coke is important because it is closely related to the efficiency of the molten metal heating-up.The first grade foundry coke is introduced .It is proved by copula melting experiment that，the temperature of liquid ironmay reach 1504℃ and is 74℃ higher than that by using metallurgical coke，which makes the cost of liquid iron reduced and the quality of casting improved.
二. Application:
It is mainly used in metallurgical and chemical industries, in producing syntheticnitrogenous fertilizer, calcium carbide,cement etc. as a very important raw material. The coke handled by our couporation is made from superior coking coal of Shanxi province. Provided with the dvantages of low ash, low sulphur and high carbon.
Our coke is well sold in European,American,Japanese and South-east Asian markets. Enquiries and orders from every where are always welcome, we are glad to offer you the best goods and service.
