DEFATTING TREATMENT FURNACE

PROBLEM TO BE SOLVED: To provide a defatting treatment furnace capable of restricting quality dispersion in defatting and damage of a ceramic molded product at the time of installing and recovery of the ceramic molded product by shortening a time required for ascending or descending temperature and adsorbing and holding a ceramic molded product without using any case.SOLUTION: A rotor 2 rotationally driven in one direction is installed in a furnace body 1 and a plurality of adsorption heads 10 are arranged at the rotor 2 while being spaced apart by a prescribed clearance in a circumferential direction. The adsorption head 10 has a plurality of suction holes 14 capable of adsorbing a plurality of ceramic molded products S at an adsorption surface 13 so as to cause the ceramic molded product to be adsorbed and held at the adsorption surface 13 during a period in which the adsorption heads 10 reach from the ceramic molded product supply part to the recovery part through a heating zone. The ceramic molded product supply part and/or recovery part of the furnace body is provided with openings 30, 31 and there are provided shutters 32, 33 for opening or closing these openings. 【課題】昇降温の時間を短縮し、匣を使用せずにセラミック成形品を吸着保持することで、脱脂の品質バラツキを抑制し、セラミック成形品の搭載、回収時におけるセラミック成形品の破損を抑制できる脱脂処理炉を提供する。【解決手段】炉体１の内部に一方向に回転駆動される回転体２を配置し、回転体２に周方向に所定間隔をあけて複数の吸着ヘッド１０を設ける。吸着ヘッド１０は、吸着面１３に複数のセラミック成形品Ｓを吸着し得る複数の吸引穴１４を有し、吸着ヘッド１０がセラミック成形品供給部から加熱ゾーンを介して回収部に到達するまでの間、吸着面１３にセラミック成形品を吸着保持させる。炉体のセラミック成形品供給部及び／又は回収部には開口部３０、３１が設けられ、これら開口部を開閉するシャッタ３２、３３を備える。【選択図】 図１
