Description

Technical Field

[0001] This utility model relates to the field of electric furnaces, and in particular to a multifunctional vacuum induction furnace. Background Technology

[0002] As is well known, a vacuum induction furnace is a high-end metallurgical equipment that uses electromagnetic induction heating technology to melt metals and alloys in a vacuum environment. It is widely used in aerospace, nuclear energy, electronics, defense and other fields.

[0003] Currently, commonly used vacuum induction furnaces have a one-piece structure. When there are multiple production processes or when production processes need to be adjusted, a single vacuum furnace cannot meet all the needs. Sometimes, due to changes in production requirements, a new vacuum furnace needs to be purchased. However, purchasing a new vacuum furnace is too costly and takes too long. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multifunctional vacuum induction furnace that can change the ingot mold chamber according to different production needs, is easy to operate, and has low cost.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional vacuum induction furnace includes a furnace body and a furnace cover. An induction coil is installed inside the furnace body. The furnace body is characterized by being detachably connected by a melting chamber and an ingot mold chamber arranged vertically. The induction coil is located inside the melting chamber. A support bracket is provided outside the furnace body. The melting chamber is fixedly connected to the support bracket, so that the ingot mold chamber is suspended in the air to facilitate the replacement of the ingot mold chamber.

[0007] As a further preferred embodiment, flanges are provided at opposite ends of the melting chamber and the ingot mold chamber, and annular grooves are provided on the outer edge of the flanges. The melting chamber and the ingot mold chamber are connected to each other by multiple sets of hook bolts hooked in the annular grooves.

[0008] As a further preferred option, an eccentrically arranged ingot mold sleeve is provided on the bottom surface of the ingot mold chamber. The ingot mold sleeve is connected to the ingot mold chamber and a lower sealing plate is detachably connected to the lower port of the ingot mold sleeve, so as to facilitate the installation of long ingot molds to cast longer metal ingots.

[0009] As a further preferred embodiment, two slides are symmetrically arranged at the bottom of the ingot mold chamber, and trolleys are slidably installed on the two slides for placing two ingot molds to be cast side by side; a push rod is connected to one side of the trolley and the push rod is sealed through one side of the ingot mold chamber for connecting a drive device to push the trolley to slide on the slide.

[0010] As a further preferred embodiment, a support plate is fixed in the ingot mold chamber by columns evenly distributed around the circumference. A bearing seat is installed on the support plate, and a rotating shaft is installed on the bearing seat via bearings. An ingot mold turntable is fixed at the upper end of the rotating shaft for evenly distributing multiple ingot molds to be cast around the circumference. A reducer is provided at the bottom of the ingot mold chamber below the rotating shaft. The output end of the reducer is connected to the rotating shaft for transmission, and the input end of the reducer is connected to a drive shaft, which is sealed and protrudes from one side of the ingot mold chamber for connecting a drive device to drive the ingot mold turntable to rotate.

[0011] The beneficial effects of this utility model are as follows:

[0012] Because the furnace body is composed of a detachably connected melting chamber and an ingot mold chamber arranged vertically, and is fixedly connected to the melting chamber by a support bracket located outside the furnace body, the ingot mold chamber is suspended in the air. This allows users to replace various types of ingot mold chambers at any time according to different product production needs, making operation convenient and production costs low. It avoids the problem of high costs and long cycles of purchasing new vacuum furnaces when there are multiple production processes or when production processes need to be adjusted.

Water jackets are respectively provided inside the outer walls of the melting chamber 6 and the ingot mold chamber 9 to allow cooling water to be introduced for water cooling of the furnace body. The induction coil is supported inside the melting chamber 6 via the hollow shaft 3. A sealing sleeve 2 is fixed to the side wall of the melting chamber 6, and the hollow shaft 3 is rotatably installed through the sealing sleeve 2 via a bearing. A support bracket 1 is provided outside the furnace body, supported on the ground. The melting chamber 6 is fixedly connected to the support bracket 1 by bolts, allowing the ingot mold chamber 9 to be suspended in the air for easy replacement.

[0023] Flanges 7 are welded to opposite ends of the melting chamber 6 and the ingot mold chamber 9, respectively. An annular groove is provided on the outer edge of the flange 7. The melting chamber 6 and the ingot mold chamber 9 are connected to each other by multiple sets of ISO high-vacuum hook bolts 8 hooked into the annular groove. Annular grooves are provided on the flanges 7 at the upper ends of the melting chamber 6 and the ingot mold chamber 9, and sealing rings are embedded in the annular grooves to improve the sealing of the connection between the melting chamber 6, the ingot mold chamber 9, and the furnace cover 5.
