Intermediate frequency furnace.com/key-electric-furnace-94/">electric furnace a simple valve quenching device the middle of a turn than the two side of the turn diameter slightly smaller in the two side of the centerline of the sensor to place a valve, the valve rod end is located in the center of the sensor, due to the rod diameter of only 8mm, so the induction is powered up, the two rod ends and heated to quenching temperature. Two V-shaped block both centers, but also set the axial position. 6kW high-frequency power heated two-valve time for 3s, the valve to reach the required temperature, put the quench tank below the quenching medium is generally oil. Valve production capacity, the valve automatically quenching device has become very necessary to quench device. IGBT super audio transistor power 80kHz 9kW, rotary table, controlled by the main drive motor, the radial positioning also motor control axial location controlled by the electromagnet. Heating time according to the process need be adjusted in the 0.1-9. 95s inside, working the beat for the heating time. 7s . The machine adopts computer control lanthanum parts sent, quit heating, cooling send function, you can set the process parameters, and display, recording, printing and other functions.
        Take some measures on the design of this machine: (1) semi-ring sensor, its current addition to the circumferential flow, the longitudinal part of the screw top and bottom can be heated; â'¡ interval positioning block cross in the screw on scan hardening, the positioning block across the screw on tight to keep the gap, screw is rotating, with heating, uniform heating can make; â'¢ installed limit deformation of the bearing screw roller, reducing the bending deformation.
       Medium frequency induction furnace is replacing the power frequency induction furnace in the foundry industry increasingly wide range of app lications. At present, the world\\ s largest change quite Power reached 8000kW. In our country, has been put into the application of intermediate frequency furnace has reached 20t (the configuration 5000kW/200Hz frequency conversion power supply). Capacity in It and the following induction furnace almost have been intermediate frequency induction furnace substitute.
