Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgy, and more specifically to an automatic centering embedded argon blowing joint. Background Art
[0002] The argon blowing joint is an equipment interface used to blow argon into the ladle during the steel smelting process. Its main function is to reduce the iron oxide content in the molten steel and improve the quality of the steel by spraying argon. Argon can form a protective layer on the surface of the molten steel, effectively preventing the molten steel from being oxidized by the air and preventing the molten steel from being contaminated by other impurities. During the process of pouring molten steel into the ladle, the surface of the molten steel is easily oxidized by contact with the air. In order to reduce this oxidation effect, the argon blowing joint is designed to inject argon into the ladle. Argon is evenly sprayed on the surface of the molten steel through the argon blowing joint, forming a protective layer of argon, thereby isolating the air and reducing the occurrence of oxidation reactions.
[0003] The existing argon blowing joints on the market are all exposed to the outside as a whole, and the splashed steel slag is easy to accumulate on the argon blowing joints, thereby damaging the argon blowing device, requiring frequent repair and maintenance, and reducing production efficiency.
