1. Avoid temperature changes:

2. Select thicker components (Contil wire) material:

3. Adjust the temperature of the components (Contair wire) according to the atmosphere of the electric furnace:

The influence of certain common electric furnace atmospheres on the maximum operating temperature of heating elements, due to the risk of "green corrosion" at 800-950 degree and 1470-1740 degree , nickel chromium Contel wire should not be used in electric furnaces with protective atmospheres containing carbon monoxide. In such cases, it is recommended to use Kangtaier alloy wire, but the heating element must be pre oxidized at 1050 degree and 1920 degree for 7-10 hours, and the heating element should be regularly re oxidized.

4. To avoid erosion of solids, fluids, and gases in electric furnaces:

Good equipment also requires well-equipped products. The operating cost of Swedish imported electric heating wire (Contel wire) is slightly higher, the replacement frequency is lower, the material consumption is less, and the service life is relatively long. These advantages have been widely used in large and medium-sized enterprises and excellent equipment. At present, small and medium-sized enterprises are also starting to replace Swedish Contel wires, which are gradually being accepted. The price is slightly higher than that of domestic electric heating wires, but in the long run, it is still a good choice. We suggest that customers need to make the best debugging according to the product equipment.
