The electric heating wire is a more common kind of heating element, its role is to convert electrical energy into heat when energized, in metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliances, glass and other industrial heating equipment and civil heating appliances and other fields are widely used. Take the electric heater heater, electric wire is the core of the heater heater, so, for the heater, the material quality of the electric wire determines the heating performance of the heater.
It is important to know that the types of electric heating wire is based on the different chemical elements and organization of the electric heating wire to be divided. The common electric wire on the market are iron chromium aluminum alloy electric wire and nickel-chromium alloy electric wire, these two kinds of electric wire as an electric heating element, in the functional performance of each has its own characteristics.
FeCrAl heating wire
FeCrAl heating wire is made of iron, chromium, aluminum three metal materials **** with the creation of the electric wire, has a high resistivity, high surface load, long service life, high operating temperature and so on, and is not prone to melting phenomenon, which can guarantee the safety of the heating pipe performance. At the same time, the iron chrome aluminum alloy electric heating wire also has good oxidation resistance, durable. However, it also has certain shortcomings, iron chrome aluminum alloy wire in the high-temperature environment, its strength is low, will be deformed as the temperature rises, and deformation is not easy to recover. Therefore, for the longer heating tube, iron chrome aluminum alloy electric wire can not require the electric wire to carry too high a temperature, in order to prevent the electric wire heating deformation and extrusion of magnesium powder, resulting in the rupture of the heating tube occurs.
Nickel-chromium alloy electric heating wire
Nickel-chromium alloy electric heating wire is made of nickel, chromium two metals combined electric heating wire, the advantage of high hardness at high temperatures, high temperatures for a long time will not be deformed, even if it is because of other uncertainties leading to the deformation of the nickel-chromium alloy electric heating wire, and its repair is also very simple. At the same time, nickel-chromium alloy electric heating wire is also non-magnetic, will not lead to the heating pipe and iron and other items such as the occurrence of suction or repulsion, the heating pipe is more secure. In addition, nickel-chromium alloy electric heating wire also has good corrosion resistance, longer service life, more durable. Therefore, the heating tube of our Tai Zhuoyang Hardware Tools adopts nickel-chromium alloy electric wire as the heating element of the heating tube, and it is precisely because of these advantages of nickel-chromium alloy electric wire that we can make single-head heating tube, explosion-proof heating tube, flange heating tube, finned heating tube and other kinds of heating tubes of our Tai Zhuoyang Hardware Tools, and each kind of heating tube has the feature of fast heating and heating safety.
