FeCrAl alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature, good anti-oxidation and anti-corrosion under high temperature. It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements.1. High service temperature, such as HRE (OCr24Al6Re Rhenium) iron-chromium-aluminum alloy wire, the maximum service temperature in the atmosphere can reach 1400 °C; 2. Long service life; 3. The allowable surface load is large; 4. Good anti-oxidation performance, the Al2O3 film formed after oxidation has good chemical resistance and high resistivity; 5. The specific gravity is smaller than that of nickel-chromium alloy; 6. High resistivity; 7. Good sulfur resistance; 8. The price is significantly lower than nickel-chromium alloy; 9. The disadvantage is that as the temperature rises, it shows plasticity, and the strength at high temperature is low.1.Raw material 2.Smelting 3.Drawing 4.Rolling 5.Annealing 6.Finished Product 7.Detection 8.Packing 9.ShippingNickel-chromium and nickel-chromium-iron resistance electric heating alloys have high resistivity, good surface oxidation resistance, high strength at high temperatures, good processability and weldability, and can be widely used in metallurgy and household Electrical appliances, machinery manufacturing, etc. as heating elements and electrical appliances as resistance materials.(1) It is forbidden to use for a long time over temperature and overload; (2) Rapid cooling is not allowed when the furnace temperature is 400°C; (3) Do not touch the electric furnace wire when loading and discharging; (4) When the furnace is working, always pay attention to whether the traffic lights on the control panel are normal, and the traffic lights should be replaced after a period of time during heat preservation, so as not to burn the electric furnace wire due to the failure of the control switch; (5) Pay attention to the working conditions of the instrument at any time, and analyze and deal with it in time when the furnace temperature and instrument indication are found to be abnormal; (6) For furnaces with a capacity of more than 100KW, it is best to install an ammeter for inspection in each heating zone, and an ammeter should be installed for each phase of the three-compartment high-temperature electric furnace.
