HEAT-TREATING SETTER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a heat-treating setter capable of heat-treating by placing a novel and large treating object, capable of stably placing the treating object without substantially causing a warp, and capable of uniformly heating the treating object. SOLUTION: This heat-treating setter introduces the treating object G into a heat treatment furnace by placing the treating object G on a placing surface 1b of a plate part 1a. The crystallized glass heat-treating setter 1 has the plate part 1a formed into a structure of welding a plate-like member 23 in a plane shape, and sets a thermal expansion coefficient range of 30 to 750°C to -10×10-7to 15×10-7/K. In this manufacturing method of the heat-treating setter 1, a plurality of glass panes are held in a plane shape; its joining end surfaces are oppositely arranged; the end surfaces are heated, softened, and welded to be formed into a welded glass pane; the welded glass pane is heat-treated and crystallized to be formed into a welded crystallized glass pane; and is processed in desired dimensional accuracy.
