Pipe mold powder is a ferrosilicon based composite materials,the alloying elements and grain
size are subject to stringent design and control,which can effectively reduce the undercooling,
inhibit the formation of carbides, slow decay time, sensitive to the size of the casting of small,
well consistent with the inoculation effect.
Pipe mold powder can be conceived to strengthen the role of an instantaneous,while eliminat-
ing the outer surface of casting porosity and pinholes. Pipe mold used in the late severe
surface cracking. Mold powder in the tube through the addition of some zinc or aluminum,can
help resolve difficult issues extubation, pipe mold powder can play a role in three breeds and
extend the life of the pipe mold.
Chemical content and size can be produced according to the demand of the customers
