ガスを循環させるための熱処理炉の輻射管におい
て、上記炉壁に炉外へ取出される輻射管の戻管部
を貫通させるための貫通孔を形成し、該貫通孔に
挿通される上記戻管部を上記加熱ガスの下流側に
向つて漸次縮径して形成し、該縮径部及びこれよ
り下流の管壁上に断熱材を被覆したことを特徴と
する熱処理炉の輻射管。 In a radiant tube of a heat treatment furnace that is inserted into the furnace through the furnace wall and circulates heated gas from outside the furnace, a return pipe section of the radiant tube to be taken out of the furnace is passed through the furnace wall. A through hole is formed, and the return pipe portion inserted into the through hole is formed by gradually reducing the diameter toward the downstream side of the heated gas, and a heat insulating material is provided on the reduced diameter portion and the pipe wall downstream from the return pipe portion. A radiant tube for a heat treatment furnace characterized by being coated with.
