Resistance Winding Fecral 0cr21al6nb 0cr25al5 Spiral Coil Heating Wire

Product Description

Resistance Winding Febral 0cr21al6nb 0cr25al5 Spiral Coil Heating Wire is a high-quality, durable and reliable heating wire with various advantages. Using high-purity materials such as 0cr21al6nb and 0cr25al5, it still exhibits excellent oxidation resistance and good electrical properties at high temperatures, ensuring its long lifespan and high efficiency. Moreover, after special tensile treatment, the product has higher strength and can withstand greater pressure and tension, avoiding damage or even fracture due to accidental induction. The use of spiral structure design not only enhances the electrification and heating effects, but also increases the stability and uniformity of the product, eliminates unnecessary hot spots and cold areas, and allows for free bending and length adjustment, making it easier to process and use.

Precautions during the use of Resistance Winding Fecral 0cr21al6nb 0cr25al5 Spiral Coil Heating Wire

1. The maximum operating temperature of Resistance Winding Fecral 0cr21al6nb 0cr25al5 Spiral Coil Heating Wire refers to the surface temperature of the wire itself in dry air, not the temperature of the furnace or the object being heated. Generally, the surface temperature is about 100 degrees higher than the furnace temperature. Therefore, considering the above reasons, attention should be paid to its operating temperature when designing an electric heating wire. When the operating temperature exceeds a certain limit, the oxidation amount of the wire itself accelerates and the heat resistance decreases, Especially the iron chromium aluminum electric heating alloy electric heating wire is prone to deformation, collapse, and even cracking, which shortens its service life.
2. The high operating temperature of the electric heating wire is also closely related to the wire diameter of the electric heating wire. Generally, the wire diameter of the electric heating wire should not be less than 3mm, and the thickness of the flat strip should not be less than 2mm.
3. The corrosive atmosphere inside the furnace is also closely related to the high operating temperature of the electric heating wire, and often affects the operating temperature and service life of the electric heating wire due to the presence of corrosive atmosphere.
4. Iron chromium aluminum, nickel aluminum, and other series of electric heating alloys, due to their different chemical compositions, have different application temperatures, antioxidant functions, and electrical resistivity, which determine the length of application temperature and service life. In iron chromium aluminum electric heating alloy materials, the component that determines the electrical resistivity is the AL element, while in nickel chromium electric heating alloy materials, the component that determines the electrical resistivity is the Ni element. At high temperatures, the oxide film formed on the surface of alloy electric heating wires also ages and damages continuously. The internal elements of its electric heating wire are constantly consumed. For example, AL, Ni, etc., and then shorten the service life, therefore, when selecting wire diameter, large specifications of wire or thicker flat strips should be used.
5. Due to the low high-temperature strength of iron chromium aluminum, Resistance Winding Fecral 0cr21al6nb 0cr25al5 Spiral Coil Heating Wire is prone to deformation at high temperatures. Improper selection or installation of the wire diameter can cause the electric heating wire to collapse and short-circuit due to high-temperature deformation. Therefore, it is necessary to consider its elements when designing the electric heating wire.
