Abstract
A method of forming a grate plate for installation as part of a grate assembly in which free flowing abrasive material is supported for movement along a path while treatment gas flows upwardly through such material. The grate plate includes a relatively thin carrier plate modified to present a highly wear resistant upper surface, the carrier plate having slots formed therein through which treatment gas flows for passage through the material. The method is one which is economical even though the carrier plate itself is formed from relatively expensive material.
