Description

Medium frequency induction furnace Technical Field The utility model belongs to the technical field of induction furnaces, and particularly relates to a medium-frequency induction furnace. Background The medium frequency induction furnace is characterized by that it is a three-phase power frequency alternating current, after rectification, it is changed into direct current, then the direct current is changed into adjustable current, and fed into alternating current flowing through capacitor and induction coil, so that high-density magnetic force line can be produced in the induction coil, and the metal material held in the induction coil can be cut, and a large eddy current can be produced in the metal material, and said eddy current also possesses some properties of medium frequency current, i.e. the free electrons of metal self-body can flow in the metal body with resistor to produce heat. The medium frequency induction furnace on the market has the following problems in the actual use process: 1. When the traditional medium-frequency induction furnace is in actual use, as the device is internally provided with more wires, the wires are completely exposed outside, and the wires can be pulled in the use process of the device, so that the wires are disconnected, and the protection performance is poor in use; 2. Most medium frequency induction furnaces are used in a process of directly placing metal to be heated before forging in a heating cabin, and when the metal is taken out after being heated, an additional device is needed at the moment and is taken out from the heating cabin, so that the medium frequency induction furnaces are inconvenient to use. Disclosure of utility model The utility model aims to provide a medium-frequency induction furnace, which aims to solve the technical problems in the background technology. The medium-frequency induction furnace comprises an induction furnace body, wherein a protective cover is sleeved on the surface of the induction furnace body, a first chute is formed in the top of the protective cover, an external threaded rod is welded on the top of the induction furnace body, the external threaded rod is positioned in the first chute, an internal thread ring is sleeved on the surface of the external threaded rod, the bottom of the internal thread ring is attached to the top of the protective cover, a holding rod is welded on the surface of the internal thread ring, and the holding rod is in an annular distribution mode. Preferably, the heating cabin is set up inside the induction cooker body, induction cooker body surface mounting dead lever, the induction cooker body outside is equipped with the layer board, the layer board is located inside the heating cabin, layer board one end welded fastening board, fixed plate side welded sleeve, the dead lever runs through the fixed plate, the dead lever is located inside the sleeve, fixed plate side fixed connection second fixing base, the second fixing base other end welded ball head.
