Deno pure iron appearance: good surface smoothness, uniform and consistent. This type of pure iron is mainly
Applications of Deno pure iron: stamping, relays, solenoid valves, electromagnetic components produced by national defense technology, magnetic shielding equipment, magnetizers, instruments and meters, switches, electromagnetic locks, DC motors, electroacoustics, automotive machine tools and electrical appliances, galvanized pots, magnetic separators, electromagnetic iron cores, electromagnetic clutches and other electronic industries.
Deno pure ferromagnetic annealing process: The sample for magnetic inspection should be annealed, and vacuum or inert gas protection should be used for annealing. Decarbonization atmosphere can also be used to prevent quality changes such as oxidation, carbonization, and corrosion that affect the accuracy of the inspection results.
Annealing process: During vacuum or inert gas protection annealing, the furnace is heated to above 900 degrees Celsius and held for 1 hour. After the holding is completed, the furnace is cooled to below 500 degrees Celsius or removed from the furnace at room temperature.
Question: Why is the electromagnetic core made of pure iron?
Answer: Electromagnets need to be able to control the strength of the magnetic field, and it is required that there is no magnetic force after power failure. Ferromagnetic substances without magnetic force will be magnetized in the magnetic field, and there will be residual magnetism after leaving the magnetic field. Soft iron has almost no residual magnetism, but steel is very strong, especially high carbon steel, which is very strong.
The grades of raw material pure iron (furnace charge pure iron) are YT0 and YT01, with high purity and excellent indicators. Raw material pure iron is known for its low carbon, low phosphorus, and low sulfur content, with a C content below 0.002, P content below 0.005, and S content below 0.004. It is your choice for various smelting processes. This type of pure iron is used in industries such as neodymium iron boron, stainless steel smelting, casting, powder alloys, electrical alloys, and hard magnetic alloys.
