Danyang Shenglong Electrothermal Chemical Co., introduce electric heating wire to yo

The oxidation resistance of Fe Cr Al and Ni Cr electrothermal alloys is generally strong. However, due to various gases contained in the furnace, such as air, carbon atmosphere, sulfur atmosphere, hydrogen and nitrogen atmosphere, these gases have a certain impact on the components under high temperature. Although all kinds of electrothermal alloys have been treated with oxidation resistance before leaving the factory, they will be in the same stage in transportation, winding and installation In order to prolong the service life, the customer is required to pre oxidize before use. The method is to heat the installed electrothermal alloy element in dry air to 100-200 ℃ lower than the maximum allowable service temperature of the alloy, keep the temperature for 5-10 hours, and then cool slowly with the furnace.
