Tube mold powder for ductile iron pipe (FeSi60)

Tube mold 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, slow down the decline time, and is sensitive to the scale of the casting. The sex is small, and the gestation effect has good consistency.

Use:
Pipe mold powder can instantaneously strengthen the inoculation, and at the same time eliminate the pores and pinholes on the outer surface of the cast pipe. When the pipe mold is used in the middle and late stages, when the inner surface of the pipe mold is severely cracked, adding a certain amount of zinc or aluminum powder to the pipe mold powder can help solve the problem of difficult drawing. The pipe mold powder can play the role of three incubations. And extend the service life of the tube mold.
