Double furnace vacuum intermediate frequency induction melting furnace
All vacuum intermediate frequency induction melting furnaces have only one vacuum chamber. There is only one intermediate frequency induction melting furnace and one ingot mold in the vacuum chamber. The ingot mold can only cast ingots for the metal melted by one intermediate frequency induction melting furnace. Since the melting of non-magnetic metals and alloys cannot rely solely on their own electromagnetic induction melting, they mainly rely on the electromagnetic induction heating and melting of the crucible body. The crucible body is a graphite crucible, and the graphite crucible cannot be made larger due to the limitations of equipment and technology. Copper alloy ingots cannot be made larger. With the high-speed modernization process of machinery and metallurgy industries, large special alloy ingots must be used, otherwise it will restrict the development process to a certain extent. For example, in the metallurgical industry, various steel mills have launched ultra-wide slab continuous casting and mold wide-side copper plates. The length is 4 meters, the net weight of each wide plate is 1500Kg, and the weight of copper alloy billet is more than 3 tons. At the same time, the thin slab continuous casting and rolling technology has been developed rapidly in China. The thickness of the continuous casting mold copper plate is large, and the net weight is more than 1700Kg. , The weight of the billet needs to be about 3.5 tons, which is difficult to meet the requirements of the existing domestic vacuum induction furnace.
 In order to solve the above-mentioned shortcomings in the prior art, a one-chamber double-furnace vacuum intermediate frequency induction melting furnace is provided that has a lower cost and can double the weight of a metal ingot.
The double-furnace vacuum intermediate frequency induction melting furnace has a vertical vacuum chamber, wherein: the vertical vacuum chamber is provided with two intermediate frequency induction furnaces, the intermediate frequency induction furnaces are respectively hinged on the bracket through the rotating shaft, and the hydraulic turning mechanism is connected with the intermediate frequency induction furnace. An ingot mold is set in the middle of the two intermediate frequency induction furnaces, and the capacity of the ingot mold can simultaneously accept the metal of the two intermediate frequency induction furnaces, and the position of the ingot mold is lower than the position of the two intermediate frequency induction furnaces.
    The horizontal cross section of the vertical vacuum chamber is elliptical.
    The beneficial effects of adopting the above technical solution: the one-chamber double-furnace vacuum intermediate frequency induction melting furnace has a vertical vacuum chamber, two intermediate frequency induction furnaces are arranged in the vertical vacuum chamber, and a large intermediate frequency induction furnace is arranged in the middle of the two intermediate frequency induction furnaces. Capacity ingot mold. Two intermediate frequency induction furnaces with graphite crucibles are used for electromagnetic induction heating and melting of the smelted metal such as copper alloy. After the metal is melted, the hydraulic turnover mechanism on the two intermediate frequency induction furnaces operates to make the intermediate frequency induction furnace rotate on the shaft Turn over, two intermediate frequency induction furnaces simultaneously or separately cast liquid metal into the ingot mold, and the liquid metal is condensed into an ingot in the ingot mold. Due to ingot mold
The capacity can accept the metal of two intermediate frequency induction furnaces at the same time, so it can produce larger copper alloy ingots. Compared with the existing vacuum intermediate frequency induction melting furnace, it can make the non-magnetic and easy to oxidize hydrogen-absorbing metal or alloy The weight of the ingot increases exponentially. The one-chamber double-furnace vacuum intermediate frequency induction melting furnace consists of two intermediate frequency induction furnaces set in a vacuum chamber, and the horizontal section of the vertical vacuum chamber is oval, the structure is more compact, and the volume of the vacuum chamber is effectively reduced. The manufacturing cost of the vacuum chamber.
