Description

Technical Field

[0001] The utility model relates to the technical field of electric heating wire production, in particular to an electric heating wire fixing platform used for electric heating wire bending test. Background Art

[0002] Heating wire can also be called electric heating wire or heating wire. Iron-chromium-aluminum and nickel-chromium electric heating alloys generally have strong oxidation resistance, but because the furnace contains various gases, such as air, carbon atmosphere, sulfur atmosphere, hydrogen, nitrogen atmosphere, etc., these gases have a certain impact on the components under high temperature use. Although various electric heating alloys are treated with oxidation resistance before leaving the factory, they will cause damage to the components to a certain extent during transportation, winding, installation and other links, which will reduce the service life. In order to extend the service life, it is required to carry out pre-oxidation treatment before use. The method is to heat the installed electric heating alloy components in dry air to 100-200 degrees lower than the maximum allowable use temperature of the alloy, keep warm for 5-10 hours, and then slowly cool them with the furnace.

[0003] The flexure test is an experiment to detect the bending degree of materials. The raw materials are bent multiple times to detect their anti-bending properties.
