Multistage heating furnace

多段式加熱炉

Abstract

PROBLEM TO BE SOLVED: To provide a compact multistage heating furnace which reduces an installation area in a factory.SOLUTION: A multistage heating furnace 100 comprises a plurality of heating furnace units 100-1 to 100-10 piled up in a vertical direction. Each heating furnace unit has: an upper heater 102A and a lower heater 101A which are vertically arranged with a heat insulation material 103A placed in between; a support pipe 104A arranged on one end portion of the upper heater 102A in a manner that horizontally extends; a support pipe 104B arranged on the other end portion of the upper heater 102A in a manner that horizontally extends; and a plurality of workpiece support rods 106 which are installed across the support pipes 104A and 104B. A rear surface of a workpiece W1 supported by the workpiece support rod 106 faces opposite to the upper heater 102A. An upper surface of the workpiece W1 faces opposite to the lower heater 101A of the heating furnace unit immediately above.
【課題】工場内における設置面積を小さくするとともに、コンパクトな多段式加熱炉を提供する。 【解決手段】多段式加熱炉100は、複数の加熱炉ユニット100−1〜100―10を垂直方向に積み上げてなる。各加熱炉ユニットは、垂直方向に断熱材103Aを挟んで重ねられた上部ヒーター102A及び下部ヒーター101Aと、上部ヒーター102Aの一方の端部上に水平方向に延びるように配置された支持パイプ104Aと、上部ヒーター102Aの他方の端部上に水平方向に延びるように配置された支持パイプ104Bと、支持パイプ104A,104B上に架け渡された複数のワーク支持棒106と、を備える。ワーク支持棒106に支持されたワークW1の裏面は上部ヒーター102Aに対向し、ワークW1の上面は上方に隣接する加熱炉ユニットの下部ヒーター101Aに対向するように配置される。 【選択図】図2
