[0002] The KR stirring desulfurization method has the characteristics of high desulfurization efficiency, low desulfurizer consumption, short operation time and low metal loss. It has been rapidly promoted in China in the past decade. The service life of the stirring head is of great significance to the technical and economic indicators of the KR stirring desulfurization process. The KR stirring head is a product that matches the steel structure and refractory materials. The existing KR stirring head is surrounded by refractory materials, which can improve the heat resistance of the stirring head, further improve the effect of molten iron pretreatment, improve the smelting rhythm, and meet the needs of steelmaking production development. In order to improve the processing efficiency of the KR stirring desulfurization method, a KR stirring head is needed, but the existing KR stirring head still has the following shortcomings:

[0003] For example, the utility model with application number 202022528534.5 discloses a KR mixing head, which reduces the size of the original inner plate of the mixing blade and welds a steel cage to the side of the inner plate of the mixing blade, so that the castable outside the inner plate of the mixing blade can be more firmly combined with the inner plate of the mixing blade, and the castable is not easy to peel off during the high-speed mixing of the mixing blade, thereby increasing the strength and service life of the KR mixing head. However, similar to the comparative documents of the above-mentioned application, when the existing KR mixing head is used, since a locking structure is not provided at the top of most KR mixing heads, the mixing head may fall off during long-term use, resulting in a decrease in the practicality of the KR mixing head and a decrease in its use efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a KR stirring head with self-locking end is proposed. Utility Model Content

[0007] Furthermore, the inner dimensions of the installation slot match the outer dimensions of the clamping block, and the limiting member is slidably connected to the installation slot via the clamping block.

[0008] Furthermore, the lower mounting ring and the connecting column are vertically distributed, and the lower mounting ring and the connecting column are fixedly connected.

[0009] Furthermore, the outer dimensions of the limiting ring match the inner dimensions of the upper mounting ring, and the upper mounting ring is connected to the lower mounting ring via the limiting ring.

[0010] Furthermore, the reinforcement component includes a central column, an iron rod, an inner plate of a stirring blade and a reinforcement layer, wherein the iron rod is arranged inside the central column, the inner plate of a stirring blade is installed at the lower end outside the central column, and the reinforcement layer is arranged outside the inner plate of a stirring blade.

[0011] Furthermore, the reinforcement component also includes V-shaped steel bars, castables and reinforcing walls. At the same time, V-shaped steel bars are added to the outside of the reinforcement layer, castables are arranged on the outside of the V-shaped steel bars, and reinforcing walls are added to the outside of the castables.

[0012] Furthermore, the number of the stirring blade inner plates is set to four, and the four stirring blade inner plates are equidistantly distributed at the outer lower end of the central column.

The internal size of the installation groove opened in the connecting column matches the external size of the limit piece, and the limit piece is installed in the installation groove by the clamping block. At the same time, the limit piece is limited as a whole after being installed in the installation groove through the setting of the clamping block, thereby avoiding the loosening of the end of the KR mixing head after long-term use. The lower mounting ring is fixedly installed on the upper end of the connecting column. At the same time, the external size of the limit ring added at the upper end of the lower mounting ring matches the internal size of the upper mounting ring, and then the upper mounting ring is limited by the limit ring during the installation process, thereby increasing the convenience of the overall installation process and further improving the use efficiency of the KR mixing head.

[0016] 2. The utility model provides a reinforcement component, so that when a KR mixing head with a self-locking end is used, the reinforcement component provided inside the mixing head body can prevent the castable material from peeling off during high-speed mixing of most KR mixing heads, which reduces the use strength and shortens the service life of the KR mixing head, resulting in the problem of reduced use efficiency of the KR mixing head. An iron rod is added inside the center column to increase the overall use strength of the center column, and the inner plate of the mixing blade is fixedly installed on the outer side of the lower end of the center column, and the stability of the inner plate of the mixing blade during use is increased by cooperating with a reinforcement layer added outside the inner plate of the mixing blade, and the contact area between the castable and the center column is increased by V-shaped steel bars, and at the same time, the reinforced wall added outside the castable prevents the castable from peeling off during high-speed rotation of the mixing head, thereby improving the overall stability of the equipment and further improving the overall service life of the KR mixing head.
