HEATING FURNACE AND PRODUCING METHOD OF GRAPHITE USING HEATING FURNACE
To provide a heating furnace with a heater having excellent durability as a result that a local high temperature portion is unlikely to occur, and a producing method of graphite using the heating furnace.SOLUTION: The heating furnace for producing the graphite includes a graphite power supply unit and a graphite main heater 3, in which a power supply rod 4a of the power supply unit and the main heater 3 are directly connected, and a directly connected portion 3b is not exposed. The power supply unit and the heater 3 are fitted or screwed together. The heater 3 is a plate-shaped slit heater formed by slits 3a provided alternately on a pair of opposite sides, and an end portion 3c of each slit 3a is processed into a circle with a diameter larger than 1/2 of a width of the slit. Thicknesses of a peripheral portion 3d surrounding the directly connected portion 3b and a peripheral portion 3e surrounding the end portion 3c of the slit are formed so as to be thicker than the other portions in the plate-shaped slit heater. The producing method of the graphite of the present invention is the producing method of the graphite using the heating furnace.SELECTED DRAWING: Figure 2
【課題】局所的な高温部分が発生し難く、耐久性に優れたヒータを備えた加熱炉、および当該加熱炉を用いるグラファイトの製造方法の提供。【解決手段】グラファイトを製造する加熱炉であって、黒鉛製の給電部と、黒鉛製のメインヒータ３とを備え、給電部の給電棒４ａとメインヒータ３とが直結していると共に、直結部３ｂが露出していない。給電部とヒータ３とが嵌合または螺合している。ヒータ３は、一組の互いに対向する辺に交互にスリット３ａが設けられて形成された板状のスリットヒータであり、各スリット３ａには、スリットの幅の１／２よりも大きい隅Ｒ加工がなされた終端部３ｃが形成されている。板状のスリットヒータは、直結部３ｂを取り囲む周辺部分３ｄ、並びに、スリットの終端部３ｃを取り囲む周辺部分３ｅが、その他の部分よりも厚く形成されている。この加熱炉を用いるグラファイトの製造方法。【選択図】図２
