Description

Technical Field

[0001] This utility model relates to the technical field of discharge devices, and in particular to a discharge device for a medium-frequency electric furnace. Background Technology

[0002] Medium-frequency induction furnaces are widely used for smelting non-ferrous and ferrous metals. Compared with other casting equipment, medium-frequency induction furnaces have advantages such as high thermal efficiency, short smelting time, less alloy element loss, wide range of smelting materials, less environmental pollution, and precise control of the temperature and composition of molten metal. Currently, when discharging, medium-frequency induction furnaces mostly use a crane to lift the ladle to the furnace outlet, and then use a hydraulic actuator to drive the furnace to rotate so that the molten iron is poured directly into the ladle. In this process, due to the large vertical drop between the ladle and the furnace outlet, the molten iron directly impacts the inner wall of the ladle or the surface of the molten iron in the ladle, which can easily cause splashing of molten iron and pose a significant safety hazard. In addition, the suspended ladle is prone to shaking after being impacted by the molten iron, resulting in poor stability. Workers need to use long poles to support the ladle, which is time-consuming and laborious and needs to be improved.

[0003] For example, the utility model patent with authorization announcement number CN220524636U discloses a discharge device for a medium-frequency induction heating furnace, which includes a base plate located on one side of the medium-frequency furnace. A first slide block is slidably connected to the top of the base plate, and a second slide block is slidably connected to the top of the first slide block. A ladle is placed on the second slide block, and a funnel is connected to the first slide block through a lifting mechanism. The funnel is located directly above the ladle, and a feed port is opened on the side wall of the medium-frequency furnace facing the funnel. The medium-frequency furnace includes a furnace frame, and a bracket is hinged to the top of the furnace frame. A furnace body is fixedly inserted through the inner side of the bracket. However, the adjustability of the furnace body during discharge is insufficient, and it cannot be guaranteed that the furnace body can discharge completely. In view of this, a discharge device for a medium-frequency furnace is proposed. Utility Model Content
