First, after electrifying the U-shaped metal, workers can suck up the iron sheet on the table, which is the magnetization process of the powerful magnet. This factory can produce all kinds of magnets. Workers fill the template with sand, smooth the surface, and then inject gas into the machine to ensure that the sand hardens. This is the most widely used sand table mold at present, and different shapes of molds can be made according to different needs. Casting: first make a sand mold with the required magnet shape, and then you can cast the magnet. These materials include copper, cobalt, sulfur, nickel, iron, aluminum and titanium. Put the metal into an induction cooker, and heat it to above 1600℃ to melt all the metal into liquid. Then the workers mix the metal materials and put them into an induction furnace. The furnace heats the metal to 1648 degrees Celsius, and all the metal melts into liquid, and then the liquid is poured into the mold. The gas in the mold causes the mold to start burning. Workers transport the burning mold to the designated position, beat the mold with a sledgehammer to make it burn quickly, and then cool the mold with a fan.
Second, the workers then use magnets to pick out metal blocks from the sand. These metal blocks are not magnetized, so the next step is to add females to the metal blocks. A set of ring metal for motor is transferred to copper tube. Put the copper tube into a large diameter spool and fill the spool with silica sand. Silica sand is used to fix the copper ring, and both ends of the spool are sealed with cement. Put the bobbin into an electric furnace for heating, and the heating treatment can make the bobbin better receive the electromagnetic field.
Third, insert a long metal rod into the copper tube and fix it with a clip. After the metal bar is charged with low voltage and high current, the metal ring will have certain magnetism, and the burr of the ring will be polished flat to make the ring magnet for the motor. This u-shaped magnet is not magnetic yet. Put a magnet on the pre-established magnetic field, open it after confirming Cixi, and this powerful magnet will be finished.
