It has the advantages of simple equipment, low energy consumption, fast smelting speed, and less metal oxidation loss, and is particularly suitable for the smelting of titanium and its alloys.

[0003] When a vacuum consumable arc furnace is in use, it is fixedly installed on the ground, and the loading and unloading are carried out at the same position. When workers perform loading and unloading, it is inconvenient to use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the drawback that when a vacuum consumable arc furnace is in use in the prior art, it is fixedly installed on the ground, and the loading and unloading are carried out at the same position, which is inconvenient for workers to use, and a rotary ground rail for a vacuum consumable arc furnace for melting titanium and titanium alloys is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A limiting component for limiting the support ring is arranged on the top of the bottom plate.

[0009] In one possible design, the rotating assembly includes a plurality of reinforcing rods fixedly connected to the inner wall of the support ring, a same annular plate is fixedly connected between the plurality of reinforcing rods, a resistance block is fixedly connected to the top of the bottom plate, the resistance block is used in conjunction with the support ring, and an annular notch is provided on one side of the support ring for use in conjunction with the molten pool.

[0010] In a possible design, two symmetrically arranged sliding blocks are fixedly connected to the bottom of the annular plate, and an annular groove is formed on the top of the abutment block, and the annular groove is slidably connected to the sliding blocks.

[0011] In a possible design, the limit assembly includes a limit block fixedly connected to one side of the support ring, a fixed block fixedly connected to one side of the base plate, a second block fixedly connected to one side of the fixed block, a groove is provided on one side of the fixed block, a mobile block slides through the inside of the groove, a screw is threaded through one side of the fixed block, one end of the screw is rotatably connected to one side of the mobile block, and the limit block is located between the mobile block and the second block.

The support ring drives the limit block to rotate until one side of the limit block conflicts with one side of the first fixed block. After unloading is completed, it is reset;

[0016] And due to the setting of the annular notch, the molten pool can remain motionless when the furnace body rotates. The setting of the slider and the annular plate can improve the stability of the furnace body when it rotates.

During normal charging and discharging, the device can be rotated by a corresponding angle, and thus it can be realized that one side of the device is dedicated to charging and the other side is dedicated to discharging. Separating the charging and discharging can improve the working efficiency. Description of the drawings
