Description

Technical Field

[0001] The utility model relates to the technical field of induction furnaces, in particular to a medium-frequency induction furnace for producing metal castings. Background Art

[0002] In the production process of metal castings, medium frequency induction furnaces are mainly used to melt metal raw materials and provide qualified molten metal solutions for subsequent casting processes. The casting process includes steps such as mold making, metal melting, casting molding, mold cleaning, precision machining and surface treatment to ensure that the quality and precision of metal castings meet the requirements. Medium frequency induction furnaces have the advantages of low energy consumption, low pollution emissions, and high metal element acquisition rate, and have been widely used in the casting field. By adjusting the power output power, operating frequency, induction coil design and other parameters of the electric furnace, the eddy current size and heating effect can be adjusted to meet specific heating needs.

[0003] When the medium frequency induction furnace is melting materials, the molten materials will be concentrated at the bottom of the furnace body, resulting in the overall lower part of the furnace body being heavy and the top being light. The existing induction furnace body is connected to the base through a rotating frame. When the furnace body is poured, the motor is used to drive the rotating frame to flip. Under the strenuous lever, the power required by the motor will be very large, so it consumes more energy. The existing induction furnace lacks a protective structure on the outside. When the connecting parts between the induction furnace and the base are broken, it will cause serious safety hazards. Utility Model Content
