HIGH TEMP. RADIATION ELEMENT

The utility model relates to a high temperature radiation element for industrial heating, composed of a U-shaped pipe-shaped basal body, a resistance wire, a high temperature infrared radiation coating, and a metallic electric wire connecting clamp. A wire groove around a pipe shaft is arranged on the pipe wall of the partial length of the closed end of the U-shaped pipe-shaped basal body; the resistance wire is embedded in the wire groove, and is sealed through the high temperature infrared radiation coating. The utility model has high temperature radiation efficiency, high temperature rising speed, long service life and convenient installation and replacement, and is suitable for the high temperature heating below the 1300 DEG C; the utility model can form series-parallel connection with the commercial voltage to use, and can be widely used for the metal heat treatment and the high temperature heating of the metal and nonmetal smelting and the sintering.
