Abstract:
1. A method of forming a sintered refractory article, comprising: positioning a green refractory body on a plurality of support plates separated by gaps, wherein the support plates are supported by a plurality of support members, each of the support members having an arcuate upper surface of constant radius of curvature and an arcuate lower surface of constant radius of curvature, the radius of curvature of the arcuate upper surface is equal to the radius of curvature of the arcuate lower surface, and each of the support members having a center of gravity displaced from a center of rotation of the support member, there being a layer of setter material disposed between the green refractory body and the support plates; heating the green refractory body to form a sintered refractory article; and wherein during the heating the green refractory body contracts, causing the support plates to translate in response to the contraction of the green refractory body and the support members to rotate in response to the translation of the support plates.
