Problems solved by technology

The structure of the high-frequency vacuum induction melting device in the prior art includes a melting chamber, a material supply chamber and a mold cooling chamber. The high-frequency vacuum induction melting device in the prior art has the following defects: (1) The mold cooling chamber is used for pouring molten soup After the cooling of the mold, a heat exchanger is installed in the mold cooling chamber. Since the mold cooling chamber needs to accommodate both the mold and the heat exchanger, the mold cooling chamber occupies a relatively large space. Therefore, during the mold cooling process, It needs to consume more energy, resulting in high energy consumption; in addition, because the heat exchanger is directly installed in the mold cooling chamber, it is not conducive to heat exchange, so that the cooling speed of the mold cooling chamber is relatively slow; (2) When the raw material is made of materials After the supply chamber is input into the melting chamber, after the melting of the raw materials is completed, it is necessary to use the sample taking device to take out the molten soup sample to check whether the material composition content of the molten soup is accurate. If the material composition content of the molten soup is accurate, it can be directly released. Soup; if the material composition of the molten soup is inaccurate (this may be caused by abnormal weighing of raw materials, abnormal operation process or other abnormal reasons), in this case, the existing technology is to use the material supply chamber to put a small amount into the melting chamber The raw materials are melted so that the material composition of the molten soup is accurate. However, due to the small amount of supplemented raw materials, it is difficult to use the material supply chamber to put a small amount of raw materials into the melting chamber in the prior art, so that it is not convenient to adjust the material composition content of the molten soup; (3 ) When using the high-frequency vacuum induction melting device of the prior art to melt raw materials, due to the unsatisfactory temperature control, it is easy to cause uneven melting and mixing of raw materials, that is, segregation phenomenon. In addition, the melting speed is relatively slow, resulting in long production cycle , so that the production efficiency is relatively low
