1.Product Feature

The spherical pitch is the advanced products developed by ourselves,made by special craft from high polymer pitch.The appearance is spherical.The spherical pitch is the high quality additive to produce iron ditch material,prefabricated parts, artesian moulding material.The softening point is fitting,the content of coking value is high,the particle size distributing rationally,which can reduce water consumption,increase mobility,improve resist dregs and stability. If used for taphole of blast furnace can help to avoid sand washout and lard,to improve the surface of castings and lengthen the life of taphole.
