BURNING FURNACE, BURNT BODY PRODUCING METHOD, AND BURNT BODY

摘要

A sintering furnace for sintering an object to be sintered formed of ceramics, fine ceramic materials, etc. to produce a sintered object and a method therefor. An insulating wall ( 28 ) and an inner shell ( 25 ) define a sintering chamber ( 16 ) for sintering an object to be sintered ( 10 ). Thermal equilibrium is maintained between the inner shell ( 25 ) and the object to be sintered ( 10 ), and the object to be sintered ( 10 ) is completely pseudo-adiabatically isolated to achieve more uniform and small energy consuming sintering. The thickness of the insulating wall ( 28 ) increases gradually from an inlet ( 20 ) toward an outlet ( 21 ). The object to be sintered ( 10 ) is fed by a carriage provided in a sintering furnace from the inlet ( 20 ) to the outlet ( 21 ) in the sintering chamber ( 16 ). Thereby, a temperature distribution corresponding to a plurality of processes can be easily formed in one furnace to sinter continuously the object to be sintered ( 10 ) in the furnace.
