Detailed

Pipe Mould Powder is a silicon iron based composite material, its alloy elements and particle size are strictly designed and controlled, which can effectively reduce undercooling, inhibit the formation of carbides, slow down the decay time, have little sensitivity to the size of the casting, and have a good consistency in the inoculation effect.

Pipe mold powder can play a transient strengthening and inoculation role, while eliminating air holes and pinholes on the outer surface of the casting pipe. When the inner surface of the pipe mold is severely cracked in the middle and later stages of use. Adding a certain amount of zinc or aluminum powder to the tube mold powder can help solve the problem of difficult tube drawing, and the tube mold powder can play the role of three times of inoculation. And prolong the service life of the pipe mold.

Usage: When producing ductile iron pipes, there will be a certain amount of carbon, which will closely combine with iron. The form of carbon in solidified cast iron is very important for the performance of cast iron pipes. If this carbon takes the form of iron carbide, the cast iron is called white iron, which is hard and brittle, and has poor practicality. If the carbon is in the graphite state, the cast iron is soft and easy to process. It is called gray cast iron, and has strong practicality. Graphite state can also be divided into flake, dense, and spherical forms, wherein the spherical form can exhibit higher strength and a more ductile form of cast iron. Therefore, in the solidification process of cast iron, it is necessary to use the auxiliary effect of additives to achieve ideal results for ductile iron pipes.
