Recognition principle and classification of electric wire features

Apr 01, 2016

Heating is the most common type of heating element, which is in the power and heat, electrical energy turns into heat energy. Heating wire a wide range of applications, many commonly used heating equipment using electric wire as heating element, heating wires in the medical, chemical, electronics, electrical appliances, metallurgy, machinery, ceramics and glass processing industry are used.

1, electric wire works

The principle of electric wire and other metal heating elements are the same, are metal power of electric phenomena. After the heating is electric current through a conductor, electrical current will produce some heat and was passed out by conductor. Heating wire itself is a metal conductor in power will give off heat, heat.

2, electric wire types

Types of heating wire is based on the heating wire element content and organizational structure,. Type of heating wire iron chromium aluminum electric wire and nickel-chrome heating wire. Two heating wires as electric heating elements, in the functional characteristics are different.

3 advantages and disadvantages of, iron-chromium-aluminum alloy heating wire

Advantage of Fe-CR alloy heating wire is running high, experiments, the maximum operating temperature of Fe-CR alloy heating wire available at 1400 ℃. Fe-CR alloy heating wire and long service life, high resistivity and surface recombination is high, and has good oxidation resistance.

The disadvantage of Fe-CR alloy heating wire is in the high temperature environment of lower intensity, as the temperature rises the plasticity of Fe-CR alloy heating wire will increase, that is prone to iron-chromium-aluminum alloy heating wire in high temperature deformation and deformation are not easily repaired.
