| 不锈钢电热管是以金属管为外壳，沿管内中心轴向均布螺旋电热合金丝（镍铬、铁铬合金）其空隙填充压实具有良好绝缘导热性能的氧化镁砂，管口两端用硅胶或陶瓷密封，这种金属铠装电热元件可以加热空气，金属模具和各种液体。]在耐高温不锈钢无缝管内均匀地分布高温电炉丝，在空隙部分致密地填入导热性能和绝缘性能均良好的结晶氧化镁粉，这种结构不但先进，热效率高，而且发热均匀，当高温电阻丝中有电流通过时，产生的热通过结晶氧化镁粉向金属管表面扩散，再传递到被加热件或空气中去，达到加热的目的。 The stainless steel electric heating tube is a metal tube as the shell, which is uniformly distributed along the central axis of the tube. The gap is filled with magnesia with good insulation and thermal conductivity. Both ends of the pipe are sealed with silica gel or ceramic. This metal armored electric heating element can heat air, metal mold and various liquids. ]High temperature electric furnace wire is evenly distributed in high temperature resistant stainless steel seamless pipe, and crystalline magnesia powder with good thermal conductivity and insulation performance is densely filled in the gap part. This structure is not only advanced, but also has high thermal efficiency and even heating. When there is current passing through the high temperature resistance wire, the heat generated diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and then transfers to the heated parts Or air, to achieve the purpose of heating. |
