Description

Technical Field

[0001] The invention relates to the technical field of steelmaking deoxidation, in particular to an adding structure for a steelmaking converter deoxidizer. Background Art

[0002] In the steelmaking process, deoxidation is a critical link, which has a decisive influence on the quality and performance of steel. The addition of deoxidizer is an important means to achieve effective deoxidation.

[0003] The traditional method of adding deoxidizers to steelmaking converters has many defects. In terms of the addition position, it can often only be added at the top of the converter. This single addition position limits the uniformity of the distribution of the deoxidizer in the molten steel, which can easily lead to insufficient local deoxidation or excessive deoxidation. From the point of view of the addition method, the deoxidizer is usually poured directly on the surface of the molten steel. Due to the light weight of the deoxidizer, it is easy to float on the surface of the molten steel and it is difficult to penetrate into the molten steel, so that the deoxidation reaction cannot be fully carried out in the entire volume of the molten steel, which seriously affects the deoxidation effect. Moreover, the traditional addition method lacks the means to accurately control the amount of deoxidizer added, and it is impossible to accurately adjust the amount of deoxidizer input according to the actual situation of the molten steel, which in turn affects the quality stability of the steel and is not conducive to improving production efficiency.

[0004] In summary, the traditional method of adding deoxidizers in steelmaking converters has shortcomings in terms of the adding position, and a new adding structure is urgently needed to solve these problems in order to improve the steelmaking deoxidation effect and steel quality.
