Description

Technical Field

[0001] The utility model relates to the technical field of skate bricks, and more specifically, to a skate brick with a positioning groove. Background Art

[0002] The ladle sliding nozzle device generally consists of an upper nozzle brick, an upper skate brick, a lower nozzle brick, a lower skate brick, a machine base, a frame, a skate box, and a protective sleeve for the lower nozzle brick used in cooperation with the skate box, etc. The upper nozzle brick and the upper skate brick are installed at the bottom of the ladle. The lower nozzle brick is tightened through the protective sleeve of the lower nozzle brick and fixed on the lower skate brick. The lower nozzle brick and the lower skate brick move together with the mechanism slider. By using the dislocation situation of the upper and lower skate bricks, the molten steel container is closed or opened to achieve the state of molten steel interception or outflow control. In order to realize the control of molten steel flow and ensure that the molten steel does not leak in the closed state, the upper skate brick and the upper nozzle brick are positioned within the machine base component of the sliding nozzle mechanism, and the upper skate brick and the upper nozzle brick should be accurately positioned and closely matched.

[0003] When the existing upper skate brick is matched with the upper nozzle brick, only the boss structure on the skate brick is used to cooperate with the corresponding groove of the upper nozzle brick to achieve the positioning of the upper skate brick. Although the positioning purpose is achieved in this way, it is easy to shift during long-term use, resulting in leakage. Therefore, we propose a skate brick with a positioning groove to solve the above existing problems. Summary of the Utility Model

[0027] Please refer to Figures 1-6 , a slide plate brick with a positioning groove, including a slide plate brick body 1, a boss 102 is fixedly connected to the upper end of the slide plate brick body 1, a through hole 101 is opened on the lower end surface of the slide plate brick body 1, the through hole 101 penetrates the boss 102, a steel hoop 2 is sleeved around the slide plate brick body 1, and a steel shell 3 is sleeved on the slide plate brick body 1; a positioning groove 8 is opened on the upper end surface of the slide plate brick body 1, there are two positioning grooves 8, and they are distributed on both sides of the boss 102, a positioning sleeve 9 is arranged inside the positioning groove 8, and the positioning sleeve 9 is fixedly connected to the steel shell 3.

[0028] Specifically, when the slide plate brick body 1 is matched with the upper water port brick, the boss 102 on the slide plate brick body 1 is used for preliminary positioning, and then secondary positioning is carried out under the cooperation of the positioning groove 8. Through such two-positioning designs, the cooperation between the slide plate brick body 1 and the upper water port brick can be made more accurate, thereby effectively preventing it from shifting; at the same time, the cooperation of the positioning sleeve 9 can reduce the wear of the positioning groove 8, thereby improving the service life of the slide plate brick body 1.

[0029] The boss 102 is in the shape of a frustum of a cone, and the height of the boss 102 is 8 mm. During operation, since the boss 102 is in the shape of a frustum of a cone, it is convenient for the boss 102 to be closely attached to the groove of the upper water port brick.

[0030] A square hole 10 is provided on the upper end surface of the steel shell 3, and the square hole 10 corresponds to the positioning groove 8. During operation, by providing the square hole 10, the positioning groove 8 can be conveniently used under the action of the square hole 10.

[0031] A circular hole 11 is provided on the upper end surface of the steel shell 3, and the circular hole 11 corresponds to the boss 102. During operation, by providing the circular hole 11, the steel shell 3 can be conveniently installed on the skateboard brick body 1 under the action of the circular hole 11.

[0032] A connecting groove 4 is provided on the upper end surface of the skateboard brick body 1. An arc-shaped clamping groove 5 is provided on the inner wall of the connecting groove 4. An elastic plate 6 is arranged inside the connecting groove 4. The elastic plate 6 is fixedly connected to the steel shell 3. An arc-shaped convex block 7 is arranged on the elastic plate 6, and the arc-shaped convex block 7 corresponds to the arc-shaped clamping groove 5.
