Description

Technical Field

[0001] The utility model relates to the technical field of slag blocking structures, in particular to a slag blocking structure for steelmaking and tapping in a converter. Background Art

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as its main raw materials. Steelmaking is completed in the converter without the aid of external energy sources, relying on the physical heat of the molten iron itself and the heat generated by chemical reactions between its components. During the converter steelmaking process, in order to prevent the slag from sinking, the outlet of the converter needs to be blocked with a slag stopper. However, the current slag stopper is not easy to adjust as a whole, and its use is very limited.

[0003] After searching, the utility model with patent publication number CN212833858U discloses a slag blocking structure for converter steelmaking and tapping, which drives the first screw body to rotate by using an electric motor, thereby driving the first screw slider to move, so as to facilitate the overall adjustment of the lateral position of the slag plug, and drives the second screw body to rotate by the electric motor, thereby driving the slag plug to adjust the longitudinal position. Although it is convenient to adjust the position of the slag plug, it is adjusted through the first screw body and the second screw body. The first screw slider and the second screw slider are prone to slight displacement due to the vibration generated during converter steelmaking, which can easily cause the slag plug to be slightly offset at the converter discharge port, and easily reduce the slag blocking effect on converter steelmaking and tapping.
