Description
Изобретение по сн етс чертежом, где представлен радиационный электронагреватель . Способ повышени долговечности выем ного радиационного электронагревател в электропечи осуществл ют следукщим образом. Рабочую среду подают через патрубок I в теплоизолированный каркас 2 электронагревател 3 и направл ют ее через каркас 2 в печное пространство. При этом используют среду того же Состава, что и в электропечи. В качестве рабочей среды может быть использован любой газ из примен емых в качестве защитного (эндо- и экзогааы, аргон и др). Дл обеспечени эффективного повышени долговечности радиационного электронагревател в электропечи необходимо , чтобы тем-пература рабочей среды была значительно ниже .температуры печи (ниже 2О С), а скорость, ее была достаточной дл обеспечени хорошей тепл передачи к ней от трубы-каркаса (5Ю м/сек). Преимущество предлагаемого способа зашиты .заключаетс в повышении полговечности радиационного электронагреватели. Фор-мула изобретени I. Способ зашиты держател электронагревател от перегрева цутем теплоизолиробани полого каркаса держател ., отличающийс тем, что, о целью повышени долговечности нагре-вател за счет снижени температуры держател , полость каркаса . продуваку..:рабочей средой. Источники информации, . прин тые во внимание при экспертизе 1.Справочник Электротермическое оборудование. Под ред. А. П. Альтгаузена. М., Энерги , 1967, с. 128. рис. 5-55. 2.СТП ОНИ 684.163-75. Нагреватели электрические радиационные. ВПО Союзэлектротерм, чертеж 5НН, 420, ОН сБ.The invention is illustrated in the drawing, which shows a radiant electric heater. The method of increasing the durability of the radiation-receiving electric heater in an electric furnace is carried out in the following way. The working medium is fed through the pipe I to the heat-insulated frame 2 of the electric heater 3 and directed it through the frame 2 to the furnace space. At the same time use the environment of the same Composition, as in the electric furnace. As a working medium, any gas from those used as protective (endo- and exohaal, argon, etc) can be used. In order to effectively increase the durability of a radiating electric heater in an electric furnace, the temperature of the working medium must be significantly lower than the furnace temperature (below 2 ° C) and its speed should be sufficient to ensure good heat transfer to it from the pipe-frame (5 U m / sec). The advantage of the proposed method of protection is. It is to increase the longevity of radiation heaters. The formulas of the invention I. The method of protection of the holder of the electric heater from overheating of the heat insulation of the hollow frame of the holder, characterized in that the purpose of increasing the durability of the heater by reducing the temperature of the holder, the cavity of the frame. blower ..: working medium.
