Description

Technical Field

[0001] The utility model belongs to the technical field of steel-making converters, and more specifically relates to a converter steel-making hopper and a converter. Background Art

[0002] Steelmaking refers to controlling the carbon content, which is generally less than 2%. Putting the pig iron for steelmaking into the steelmaking furnace and melting it according to a certain process to obtain steel. Steel products include ingots, continuous casting billets, and various steel castings directly cast. The steel usually refers to steel rolled into various steel products. Steel belongs to ferrous metals, but steel is not completely equal to ferrous metals. The main raw materials for steelmaking are molten iron or pig iron with a high carbon content and scrap steel. In order to remove impurities in the molten iron, it is also necessary to add oxidants, deoxidizers, slag-making materials, and ferroalloys and other materials to the molten iron to adjust the composition of the steel. After the molten iron or pig iron with a high carbon content is added to the steelmaking furnace, it is oxidized and removed through processes such as oxygen supply and blowing, adding ore, and decarbonization. Finally, alloys are added for alloying to obtain molten steel. In the existing converter steelmaking process, a large amount of raw materials are usually put into the hopper at one time. When feeding, it is easy to get stuck in the feed port due to the different shapes of the raw materials and cannot be fed. In addition, the temperature near the converter is high, and it is difficult to manually approach and clear. Utility Model Content
