The metal mica heating ring manufactured by the electric heating coil manufacturer is made of stainless steel, copper and iron. The mica sheet with high insulation and fire resistance is wound on the electric heating wire, and the core of the electric heating wire has a good insulating refractory layer on both sides. When the manufacturer of cast copper heating coil uses metal mica heating coil, Nanjing cast copper heating coil must be installed firmly, not loose, and the use voltage should not exceed 10% of the rated voltage, and should be effectively grounded. Even if its electrothermal components have been carefully inspected and dried, it is necessary to check again before use for safety, whether there is leakage or short circuit. Cast copper heating rings and electrothermal components should be placed in a dry place, not damp, if not used for a long time, insulation resistance is less than 5M, should be placed in the drying oven for 2-3 hours, the price temperature of the electrothermal ring is 150-200 C. Metal mica heating ring has the characteristics of convenient installation, fast heat transfer, good insulation, and no restriction on the size and type of heating tube. It is mostly suitable for plastic industry and chemical industry.
Stainless steel electric heating tubes will be rusty if they are used for a long time. If rusted, how should we solve them? Yancheng Xu Yao gives us a piece of advice: spray or pickle cream to assist the rust parts to re passivate to form chromium oxide film, so that it can restore the corrosion resistance. The pickling paste is applied on the surface to be treated by Nanjing copper casting heating ring. The thickness of the coating is 0.5-2 mm. The reaction time is usually more than 3-10 minutes. When the temperature is below 0 or the thickness of the oxide skin is below 0 C, the time should be prolonged appropriately.
