The product is processed by water washing coal, high bright carbon components, modified starch and other materials.

It has the advantages of low ash content, high volatile content, strong bright carbon formation ability, low gas generation, wide temperature generation and obvious coke slag characteristics.

Pulverized coal can be completely replaced in production, and its addition amount is only 1/3-1/2 of pulverized coal. Recycling can reduce the mud content and water content of molding sand, improve the fluidity and improve the performance. 

Reducing the casting defects such as sticky sand, pores and sand holes and improving the surface quality has a remarkable effect.
