Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a medium frequency furnace with an automatic feeding structure. Background Art

[0002] The medium frequency furnace is mainly used for heating and melting metal materials. It converts ordinary industrial frequency alternating current into medium frequency current, converts three-phase alternating current into direct current, and further converts it into adjustable medium frequency current. This current generates high-density magnetic lines in the induction coil, thereby cutting metal materials and inducing eddy currents inside the metal, thereby converting electrical energy into thermal energy, and realizing rapid heating and melting of the metal.

[0003] Since most of the medium frequency furnaces have a flipping mechanism, it is convenient for the unloading operation of the molten metal. However, the movable medium frequency furnace body will affect the loading of the medium frequency furnace by the loading mechanism. Therefore, the Chinese utility model patent disclosed by the existing publication number CN221122969U: a furnace cavity suspended medium frequency electric furnace, the application utilizes the setting of the feeding mechanism, that is, the feeding mechanism is composed of a discharge tray, a conveyor, a support frame and a guide tray and other components. The material can be transported to the discharge tray by the conveyor, and the material passes through the inclined discharge tray into the guide tray, so that the material enters the smelting crucible, so that there is no need for manual operation, reducing the probability of personal injury. However, since the guide tray in the application is rotatably installed on one side of the discharge tray, and the guide tray is turned up and down by means of a spring sheet, the turning of the furnace body is not affected. However, after the spring sheet has been reciprocated and bent a certain number of times, a batch of metal will appear, thereby causing the initial position of the spring sheet to change, thereby affecting a normal turning and resetting of the guide tray, and then affecting the later feeding and adding.
