HIGH FREQUENCY HEATING DEVICE

摘要: PURPOSE:To prevent electrical discharge between the adjoining coiled parts of an electric heating coil and to increase infrared ray radiating efficiency titled device by a method wherein electroconductive substance is coated on surface insulating protective tube incorporating therein heater for grill, thereby shield high frequency current. CONSTITUTION:Semitransparent qualtz used produce 12 film 11 MOSi2 formed upper half plasma spraying method. Then 13 made wire Fe-Cr-Al inserted into fixed insulators 14 are attached both ends 12, respectively. For substance, metal such as gold, silver or platinum, alloy stainless steel Ni-CrFe-Cr-Al low temperature region silicate MOSi2, TiSi2 SWi2, boride TiB2 FeB2, carbide SiC, B4C, ZrC TiC nitride TiN ZrN region.
