pipe powder

Pipe powder is a ferrosilicon-based composite material. Its alloying elements and particle size have been strictly designed and controlled. It can effectively reduce the degree of subcooling, inhibit the formation of carbides, and slow down the decay time. The size sensitivity is small, and the inoculation effect has good consistency.

Pipe Powder can instantly strengthen the inoculation, and at the same time eliminate the pores and pinholes on the outer surface of the casting pipe. When Pipe Powder is used in the middle and late stages of the tube mold, when the inner surface of the tube mold is severely cracked, a certain amount of zinc powder is added to Pipe Powder. , Silica-aluminum powder can help solve the problem of difficult extubation, and tube mold powder can play the role of three incubations. And extend the service life of the tube mold.
