APPARATUS FOR FABRICATING SINTERED BODY AND FABRICATION METHOD OF REACTION BONDED SILICON CARBIDE POROUS BODY BY CONTINUOUS PROCESS USING THE SAME

An apparatus for manufacturing reaction sintered bodies is provided to overcome size limitation of a heating furnace by using a continuous sintering process when manufacturing reaction bonded silicon carbide porous workpieces with various shapes and sizes including plates and tubes, and a method for manufacturing reaction bonded silicon carbide porous bodies by a continuous process using the same is provided. An apparatus for manufacturing a reaction sintered body comprises a transfer unit(14), a formed body injection part(12), a heating part(13), a sintered body discharge part, a first vacuum shutter(17), a second vacuum shutter(18), and a heating furnace. The transfer unit transfers formed bodies. The formed body injection part, heating part, and sintered body discharge part are included in the transfer unit and arranged in order in a direction that the formed bodies are transferred. The first vacuum shutter is installed between the formed body injection part and heating part such that the first vacuum shutter can be opened or closed to divide the formed body injection part and heating part. The second vacuum shutter is installed between the heating part and sintered body discharge part such that the second vacuum shutter can be opened or closed to divide the heating part and sintered body discharge part. The heating furnace is installed on the circumference of the heating part to form a hot zone in the heating part.
