AI Technical Summary
Technical Problem
During the smelting of medium-frequency furnaces, rare earth alloys are severely oxidized on the surface of the molten steel, resulting in a low yield of rare earths.
Method used
A tool for smelting rare earths in medium-frequency furnaces is designed, including a storage cylinder and lifting rod. The rare earth alloy is placed in the storage cylinder, and the lifting rod inserts the storage cylinder into the middle and lower part of the steel so that the rare earth alloy is fully melted and evenly distributed.
Benefits of technology
Through this tool, the melting and dissolution time of rare earth alloys in the steel liquid is increased, the uniform distribution of rare earths is promoted, the oxidation of rare earths is reduced, and the rare earth yield is improved.

Abstract
The utility model discloses a tool for adding rare earth in intermediate frequency furnace smelting, which comprises a containing cylinder, a sealing assembly is arranged above the containing cylinder, the sealing assembly comprises a cover body clamped on the outer surface of the containing cylinder, the bottom surface of the cover body is fixedly connected with an annular sealing plate, the outer surface of the containing cylinder is fixedly connected with a lifting rod, and the lifting rod is fixedly connected with the sealing plate. A connecting assembly is installed in the containing cylinder and comprises an annular carrying plate fixedly connected to the inner wall of the containing cylinder, an annular groove is formed in the upper surface of the annular carrying plate, and the bottom face of the annular sealing plate makes contact with the inner bottom wall of the annular groove. According to the device, a medium-frequency rare earth smelting method is optimized, rare earth alloy is contained in the containing cylinder, the rare earth alloy in the containing cylinder is directly inserted into the lower middle portion of molten steel through the lifting rod, the melting and dissolving time of the rare earth alloy in the molten steel is prolonged, rare earth is promoted to be evenly distributed, and the problem that rare earth is seriously oxidized is solved; and the rare earth yield is improved.
