AI Technical Summary

Technical Problem

In existing technologies, mechanical slag removal mechanisms cannot effectively remove impurities from the surface of the smelting furnace in all directions, and the use of slag-collecting agents will generate dust and harmful gases, which limits the production of high-purity ferroalloys and cast iron with strict composition requirements.

Method used

A smelting furnace impurity removal device was designed, which utilizes a combination of an air blowing ring and a slag removal screen. The air blowing ring blows air to collect impurities to the center of the smelting furnace, and the slag removal screen removes the impurities. It is also equipped with an air extraction device to remove dust and high-temperature gases.

Benefits of technology

It achieves all-round removal of impurities without the need for slag-forming agents, simplifies the operation process, improves the working environment, and is suitable for the production of high-purity ferroalloys and cast iron with strict composition requirements.

Abstract

This utility model discloses a smelting furnace impurity removal device, belonging to the field of smelting furnaces. It includes a rotating base with a liftable lifting arm on the base. A cantilever beam is located at the top of the lifting arm, and a slag removal rod is located below the end of the cantilever beam. A slag removal screen is located at the lower end of the slag removal rod. It also includes an air blowing ring, which is fixed to the slag removal rod with several connecting rods around its center. The air blowing ring is positioned above the slag removal screen, and its outer diameter is smaller than the inner diameter of the smelting furnace. The bottom surface of the air blowing ring is tapered, and several air blowing holes are arranged circumferentially on the tapered surface, communicating with the inside of the air blowing ring. The airflow blown from the air blowing holes is directed obliquely downwards towards the inner side of the air blowing ring. This structure can gather impurities without the need for a slag-collecting agent, and then remove all impurities using mechanical slag removal.
