What are the characteristics of high-temperature heating wire:
1. High resistivity to save materials; Under the temperature coefficient of resistance, the resistance is uniform and stable.
2. High melting point, no decomposition or evaporation at high temperature, good stability in use.
3. The coefficient of thermal expansion is small to ensure that the volume change of the electric heating element is small.
4. Good high temperature oxidation resistance, thereby prolonging the life of electric heating elements in air.
5. Good chemical stability, no chemical reaction with various gases and refractories, so as not to be damaged by corrosion.
6. Good high temperature strength, no reduction in service life due to brittle changes.
7. Good hot and cold processing and formability, so as not to process into electric heating elements of different shapes.
8. Good installation and maintenance performance, easy to weld, turning, cold bending and other operations, so as to facilitate maintenance.
9. Low production cost and cheap price
10. The market is easy to purchase
What is the material of high temperature heating wire:
Heating wire is iron-chromium-chromium high-resistance electrothermal alloy, which has the characteristics of high resistivity, small temperature coefficient of resistance and high service temperature. At high temperature, the heating wire has good corrosion resistance, especially suitable for use in atmospheres containing sulfur and sulfides, and the price is low, which is an ideal heating material in industrial electric furnaces, household appliances and far-infrared devices.
Electric heating alloy: according to the content of its chemical elements and different microstructure, it can be divided into two categories: one is the iron chromium aluminum alloy series, the other is the nickel-chromium alloy series, they have their own advantages as electric heating materials, and are widely used.
The main uses of heating wire: metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliances, glass and other industrial heating equipment and civil heating appliances.
