Tube molding powder

Tube mold powder is essentially a ferrosilicon-based composite material, which is less sensitive to the size of the casting and has a good consistency in the inoculation effect.

The alloying elements and particle size of the tube mold powder are strictly designed and controlled, which can effectively reduce the degree of supercooling, inhibit the formation of carbides, slow down the decay time, limit the formation of hydrogen pores and nitrogen pores, and have little sensitivity to the size of castings. The inoculation effect was very consistent. The pipe mold powder can instantly strengthen the inoculation effect, and at the same time eliminate the air holes and pinholes on the outer surface of the cast pipe. Manganese and aluminum powder can help solve the problem of difficult extubation, and tube mold powder can play the role of three inoculation. And prolong the service life of the pipe mold.
