ABSTRACT:
Reduction of porosity and control of graphitization in the centrifugal casting of tubular metal articles are achieved providing on the active surface of a metal mold by a densified and contoured lining of binderless particulate refractory material, at least 20% by weight of the particles in all of the lining being angular particles, at least 25% by weight of the particles in that portion of the lining in contact with the metal mold having predetermined particles size and/or thermal conductivity. The lining may comprise both a primary layer, formed of particles having good thermal conductivity and/or a relatively larger particle size, and a facing layer formed, e.g., of a milled refractory flour.
