Abstract

A wear part for sliding gates used for the outlet of vessels which contain metal melts therein, the wear part being for example a sliding plate, a base plate, an inlet tube or an outlet tube. The wear part includes a refractory material surrounded by a metal mantle, where a fireproof refractory concrete is poured into a mold and hardened therein so that the mold serves as the metal mantle when the concrete has hardened. A lining surrounding a through-bore in the wear part may be cast therewith. The wear part is preferably clamped in a supporting frame.
