Single introduction to what is the heating wire?
Iron chromium aluminium, nickel-chromium electric heating alloy its antioxidant properties are generally strong, but because the furnace contains a variety of gases, like air, carbon atmosphere, sulfur atmosphere, as well as hydrogen, nitrogen atmosphere, etc., these gases on the components in the use of high temperatures have a certain impact, although a variety of electric heating alloys in the factory before the antioxidant treatment, but in the transport, winding, installation and so on will be caused to a certain degree of damage to the components, and reduce the Service life, in order to extend the service life, the requirements of pre-oxidation treatment before use, the method is to install the finished electric heating alloy components, in dry air, electrically heated to below the maximum allowable alloy temperature of 100-200 degrees, insulation for 5-10 hours, and then with the furnace can be slow-cooled.
Classification:
Electric heating alloy: according to the content of its chemical elements and organisational structure, can be divided into two major categories:
One category is iron chromium aluminium alloy series;
The other category is nickel-chromium alloy series, they as electric heating materials have their own more advantages, and are widely used.
Main uses:Metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliances, glass and other industrial heating equipment and civil heating apparatus.
