Description

Technical Field

[0001] The utility model relates to the technical field of converter steelmaking, in particular to an automated converter steelmaking device. Background Art

[0002] Converter steel refers to steel made in a converter using liquid pig iron as raw material. High-pressure air or oxygen is blown into the molten pig iron from the top, bottom, and sides of the converter to oxidize and remove impurities in the pig iron. During the automated converter steelmaking process, the converter needs to be tilted to add auxiliary materials. Long-term addition of auxiliary materials can easily cause corrosion to the furnace wall, which can easily shorten the service life of the converter.

[0003] In order to solve the above problems, the utility model with patent publication number CN217077667U discloses an auxiliary material adding device for automated steelmaking in a steelmaking converter. By setting a feeding cup, when the accurate amount of auxiliary material needs to be added, the handle is first pushed to close the insert plate at the bottom of the feeding cup, and then the auxiliary material is added inside the feeding cup. A scale is provided on the outside of the feeding cup to facilitate observation of the amount inside the feeding cup. The device facilitates accurate addition of the amount of auxiliary material. Although it is convenient for quantitative addition of auxiliary materials to converter steelmaking, it adds auxiliary materials by moving or lifting the discharge port horizontally, which is not convenient for adjusting the adding angle according to the actual auxiliary material adding range, and has high limitations when adding auxiliary materials.
