1. The performance of electric heater The electric heater (electric heating tube) is a metal tube as the shell, and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed along the central axis of the tube. The gap filling and compaction has good insulation and thermal conductivity. The magnesia sand is sealed with silica gel or ceramic at both ends of the nozzle. This metal-clad electric heating element can heat air, metal molds and various liquids.
