[0002] The medium frequency furnace is a power supply device that converts 50HZ industrial frequency AC power into medium frequency (300HZ to 1000HZ), converts three-phase industrial frequency AC power into DC power after rectification, and then converts DC power into adjustable medium frequency current, which is supplied to the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the coil, cutting the metal material contained in the coil, generating large eddy current in the metal material, and heating the metal by electromagnetic induction principle;
[0003] A Chinese patent publication (publication number: CN219572646U) discloses an intermediate frequency furnace, which includes a bottom plate, a heating mechanism, a hydraulic rod, a cooling pipe and a fixing mechanism. The top of the bottom plate is equipped with a heating mechanism, the left and right sides of the heating mechanism are equipped with hydraulic rods, the left and right sides of the front surface of the heating mechanism are equipped with cooling pipes, and the inner bottom of the heating mechanism is equipped with a fixing mechanism. The intermediate frequency furnace can melt the metal material put into the crucible mold through the cooperation of the furnace body, the crucible mold and the coil in the heating mechanism, and the pad block at the bottom end of the frame is processed. The furnace body can be supported, the force borne by the hydraulic rod can be reduced, and the service life of the hydraulic rod can be increased. The overall frame is a steel frame structure, which can reduce the overall weight of the medium frequency furnace. The bottom end of the outer wall of the crucible mold can be clamped through the work of the fixing mechanism, so that the user can disassemble the crucible mold, which can improve the maintenance and replacement efficiency of the crucible mold. However, in actual use, the heated material is directly discharged into the material trough for conveying the material. There is a large temperature difference between the material trough and the material, which leads to the risk of solidification of the melted material before pouring. For this reason, a medium frequency furnace with a preheating function is proposed. Utility Model Content

The two cylinders 23 are respectively located in front and behind the shell 21, and the telescopic ends of the two cylinders 23 are hinged to the lower surface of the first fixed plate 22. Through the setting of the dumping mechanism 2, when the material is heated, the cylinder 23 is started to drive the shell 21 to be lifted, and the bottom of the shell 21 is hinged to the platform 1, so that the shell 21 is tilted, which is convenient for the shell 21 to drive the furnace body 31 to pour out the material in the furnace body 31.
[0028] In one embodiment, the heating mechanism 3 also includes a furnace body 31, the inner wall of the shell 21 is fixedly connected to the furnace body 31, and the outer part of the furnace body 31 is provided with a first heating coil 32; through the setting of the heating mechanism 3, the first heating coil 32 is installed on the outer wall of the furnace body 31, and the first heating coil 32 is started to heat the material in the furnace body 31.
[0029] In one embodiment, the outer wall of the furnace body 31 is connected to a first discharge chute plate 33 ; the first discharge chute plate 33 is provided to facilitate guiding the flow direction of the material when the furnace body 31 is tilted.
