    Lost foam casting of metallurgical pellets

    In metallurgy(all kinds of mineral powder) and anthracite briquette forming, the dry and wet briquette strength, anti explosion and compression resistance are improved. Reduce it The dosage of the preparation ensures the roasting process of the pellet and inhibits the grade decline of the pellet (concentrate).The
    excellent increase of EPC Viscosity, air permeability and fluidity ensure the uniform film-forming of the mold surface coating, the finished product surface has no pores, good finish, easy processing, etcadvantage
