A comprehensive understanding of the electric heating wire of the electric heating sleeve

       The electric heating sleeve is heated by electric wire to reach the temperature used by the customer. The electric furnace wire includes two types: iron chromium aluminum alloy electric furnace wire and nickel chromium alloy electric furnace wire. The former is an alloy material of ferrite structure, and the latter is an alloy material of austenite structure. The electric furnace wire is made of high-quality iron-chromium-aluminum and nickel-chromium electrothermal alloy wire, and is controlled by computer to control the power of the wire, and is wound and formed by a high-speed automatic winding machine. It is characterized by high temperature resistance, fast heating, long service life, stable resistance, low power deviation, even pitch after stretching, and bright and clean surface.
The characteristics of iron chrome aluminum electric furnace wire are:
1 The use temperature is high, such as HRE iron chrome aluminum alloy wire in the atmosphere, the maximum use temperature can reach 1400 ° C;
2 long service life;
3 allowed surface load is large;
4The oxidation resistance is good, and the AI2O3 film formed after oxidation has good chemical resistance and high electrical resistivity;
5 specific gravity is less than nickel-chromium alloy;
6 high resistivity;
7 good sulfur resistance.
