[0025] In the above technical solution, considering that in the process of extracting molten metal after melting metal in an induction furnace, it may be necessary to additionally use a machine to tilt the furnace body so that the molten metal flows out through the discharge port, which increases the complexity of the steps. At the same time, if an accident or improper operation occurs, it may cause the metal to splash out, resulting in burns or other safety accidents. To solve such problems, the specific operation is as follows: By installing the furnace body 4 and the furnace lining 5 in the placement plate 2 and further fixing and supporting them by using the support assembly, and then using the lifting assembly, by starting the hydraulic cylinder 11 to drive the placement plate 2 to rotate around the axis of the mounting frame 7 and the fixing block 8, so that the furnace body 4 tilts, and then the molten metal is extracted through the discharge port 6.
