Precautions for using customized welding heating wires
1. When designing the heating wire, it should be based on the power wiring method, reasonable surface load, and correct wire diameter selection;
2. Before installation, the heating wire should undergo a comprehensive inspection of the furnace to remove any potential hazards such as ferrite, carbon deposition, and contact with the electric furnace. Short circuits should be avoided to prevent furnace wire breakdown;
3. The heating wire should be correctly connected according to the designed wiring method during installation;
4. Before using the heating wire, the sensitivity of the temperature control system should be checked to prevent temperature failure, which may cause the electric furnace wire to burn out.
5. The series of electric heating alloys such as iron chromium aluminum and nickel aluminum, due to their different chemical compositions, have different usage temperatures, oxidation resistance, and electrical resistivity, which determine the length of usage temperature and service life. In iron chromium aluminum electric heating alloy materials, the component that determines the electrical resistivity is the AL element, while in nickel chromium electric heating alloy materials, the component that determines the electrical resistivity is the Ni element. At high temperatures, the oxide film formed on the surface of alloy components also ages and damages continuously. The internal elements of its components are constantly consumed. For example, AL, Ni, etc., in order to shorten the service life, therefore, when selecting wire diameter, larger specifications of wire or thicker flat strips should be used.
