The centrifugal cast dies are usually coated with some sort of
refractory liner, both for the purpose of protecting the dies from
the action of the heat of the molten metal and for the purpose of
preventing too rapid cooling of the metal. If gray cast iron were
the metal being cast, such rapid cooling would result in the
formation of chills in the castings, which would render the
metallurgical structure of the casting unusable for most purposes.
As you know the tubular metal castings are made in permanent
cylindrical metal dies.
A metal casting tube is centrifugally formed in a metal die.The die
comprises an annular hollow cylindrical body of metal having spines
on its outer cylindrical surface generally isolated from one
another and extending generally radially, and a refractory coating
having a substantially uniform thickness at least equal to the
maximum length of said spines and interloclied with said spines
whereby said coating is secured to the body for removal of the
coating from the die along with the body.
Outstanding Features:
1.We use Spetrometer to control the chemlcal elements;
2.We check the matrix with our mlcroscope;
3.We can do fully machining on the sleeve parts.
4.We adopt Centrifugal Cast process with higher efficiency to shortening the process time;
5.Production Process: centrifugal cast process + machining process
7.We can make the cast sleeves as per customer design.
8.Diameter: 50mm - 500mm; Length: less than 400mm.
