Title:
BURNING FURNACE, BURNT BODY PRODUCING METHOD, AND BURNT BODY
Document Type and Number:
WIPO Patent Application WO/2002/032831
Kind Code:
A1
Abstract:
A burning furnace and a method of producing burnt bodies, wherein a burning-subject formed of ceramic material, fine ceramic material or the like is burnt to produce a burnt body. A heat insulation wall (28) and an inner shell (25) define a burning chamber (16) for burning a burning-subject (10). Thermal equilibrium is maintained between the inner shell (25) and the burning-subject (10), and the burning-subject (10) is quasi perfectly heat-insulated, so that more uniform, low-energy burning can be attained. Further, the thickness of the heat insulation wall (28) is gradually increased from an inlet (20) toward an outlet (21). By means of a carriage furnished to the burning furnace, the burning-subject (10) is transferred within the burning chamber (16) from the inlet (20) to the outlet (21). This allows a temperature distribution corresponding to a plurality of processing steps to be formed easily in a single furnace, making it possible to burn the burning-subject (10) continuously in the same furnace.
