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.
