CONTINUOUS FIRING FURNACE
PROBLEM TO BE SOLVED: To provide a continuous firing furnace which can be operated continuously over a long time and in which recrystallized SiC can be produced efficiently and continuously since plugging due to SiO gas or the like is not caused in an exhaust passage and a deposited material due to the SiO gas does not exist also in the continuous firing furnace.SOLUTION: The continuous firing furnace is used for continuously firing a SiC particle-containing compact at 2,000-2,300°C to produce the recrystallized SiC. The continuous firing furnace is characterized in that the exhaust passage 25 for exhausting the SiO-containing gas existing in the furnace while keeping the temperature thereof at 1,500-1,900°C is arranged in the midst of the continuous firing furnace.SELECTED DRAWING: Figure 4
【課題】排気経路にＳｉＯガス等に起因する詰まりが発生せず、また、連続焼成炉の内部にもＳｉＯガスに起因する堆積物が存在しないため、長時間に渡って連続操業が可能で、効率よく、連続的に再結晶ＳｉＣを製造することが可能な連続焼成炉を提供する。【解決手段】ＳｉＣ粒子を含む成形体を２０００〜２３００℃で連続的に焼成処理することにより再結晶ＳｉＣを製造するための連続焼成炉であって、上記連続焼成炉の途中に、炉内に存在するＳｉＯを含むガスを、１５００〜１９００℃の温度を保ちながら排気する排気経路２５が設置されていることを特徴とする連続焼成炉。【選択図】図４
