Explanation of the Structure, Performance, and Use of Heating Wire Products

The classification of electric heating wires can be divided into two categories: one is the iron chromium aluminum alloy series, and the other is the electric heating alloy: according to its different chemical element content and organizational structure. The other type is the nickel chromium alloy series, which has various advantages as electric heating materials and is widely used.

The main uses of electric heating wire

Industrial heating equipment and civilian heating appliances for metallurgical machinery, medical, chemical, ceramic, electronic, electrical, glass, and other industries.

The maximum operating temperature of the heating wire can reach 1400 degrees Celsius, and the main advantages and disadvantages of the 2 iron chromium aluminum alloy series are: advantages: iron chromium aluminum electric heating alloy has a high operating temperature. 0Cr21A 16Nb0Cr27A 17Mo2, etc.) has a long service life, high surface load, good antioxidant performance, high resistivity, and low price.

Defects: Mainly due to low high-temperature strength, the plasticity increases as the application temperature increases, and the components are prone to deformation, bending, and repair. The main advantages and disadvantages of the 3 nickel chromium electric heating alloy series are that they are not easily deformed under high temperature use:

Advantages: The high-temperature strength is higher than that of iron chromium aluminum. Its structure is not easily modified, has good plasticity, is easy to repair, has high radiation rate, no magnetism, strong corrosion resistance, and long service life. Due to the use of scarce nickel metal materials, the price of this series of products is several times higher than that of iron chromium aluminum, and the operating temperature is lower than that of iron chromium aluminum.

2、 The following items should be noted during the application of heating wires

It does not refer to the temperature of the furnace or the heated object, but the maximum operating temperature of the element refers to the surface temperature of the element itself in dry air. Under normal conditions, the external temperature is about 100 degrees higher than the furnace temperature. Therefore, considering the above reasons, when designing components, attention should be paid to their operating temperature. When the operating temperature exceeds a certain limit, the oxidation amount of the component itself increases, and the heat resistance decreases. Especially for iron chromium aluminum electric heating alloy components, they are prone to deformation, collapse, and even fracture, which shortens their service life.

The most basic function of an electric heating tube is to heat it. In different working environments, the materials used for the manufacturing of electric heating tubes are also different. For us, the most commonly used electric heating tube is probably used to heat water.

Electric heating pipes for water heating can also be divided into large electric heating pipes for boiler applications and small electric heating pipes made by individuals according to their respective applications. Nowadays, in order to prevent rust, many electric heating pipes have undergone a lot of chemical treatment. The most common method we use is to treat the surface of the electric heating tube with copper. Of course, it's also aluminum. Cast aluminum heaters are mainly divided into: cast aluminum heating rings with air slots, air-cooled cast aluminum heating rings, cast aluminum heaters for medical devices, circular cake type cast aluminum heating plates, plug type cast aluminum heating plates, right angle type cast aluminum heating plates, extruder cast aluminum heaters, water-cooled cast aluminum heaters, cast aluminum heating rings with air slots, injection molding machine cast aluminum heating rings, and supply of foam machine cast aluminum heating rings. The copper casting heater is mainly divided into: copper casting heating plate, granulator copper casting electric heating plate, drum type copper casting heater, C-type copper casting heater, right angle granulator copper casting heating plate, etc
