摘　　要：第一汽车制造厂自制的电辐射管,经实验证明效果良好。电热体材质为OCr27A17Mo2,直径为7 mm,表面负荷为1.9～2.3W/cm^2 左右。辐射管壁用耐热钢板焊接而成,材质为Cr20Ni14Si2,壁厚为上厚下薄,每根辐射管的功率为5～6 kW,寿命估算为10～12个月。经在多用炉中使用,实测炉温差达±5℃。The electric radiant tubes which are self-made by No.1 Automobile manufactory, are testified to be effective in practice. The material of the electroheat element is 0Cr27A17Mo2, the diameter and surface loading of that is 7 mm and 1.9-2.3W/cm2 respectively. The wall of the radiant tube welded by Cr20Ni14Si2 steel plates, is thick in the upper and thin in the lower. The power of each of the radiant tube is 5 - 6 kW, the longevity used in multipurpose furnaces is estimated to be 10-12 months. Its temperature uniformity in the tested furnace is about+++++++++± 5 ℃.
