Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical accessories, and in particular relates to a high-strength bottomless integral impact plate. Background Art

[0002] The tundish is a refractory container used in short-process steelmaking. It first receives the molten steel poured from the ladle, and then distributes it to each crystallizer through the tundish water outlet. The impact plate is an important part of the tundish, used to withstand the impact of the molten steel. The impact resistance of the impact plate directly affects the safety and service life of the tundish.

[0003] At present, the existing impact plates have poor impact resistance. When molten steel impacts, the impact buffering effect on the molten steel is not strong, resulting in a short service life. Utility Model Content

[0004] The utility model aims to provide a high-strength bottomless integral impact plate to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength bottomless integral impact plate, comprising a plate body, a circular buffer groove is provided on the top of the plate body, a groove is provided on the bottom of the circular buffer groove, a support plate is slidably installed inside the groove, a buffer column is fixedly installed on the top of the support plate, a plurality of scattered pits are provided on the surface of the buffer column, and elastic support balls are fixedly connected to the inner bottom wall of the groove and the bottom surface of the support plate.

[0006] As a preferred embodiment, the side walls of the plate body are arranged inclined.

[0007] As a preferred embodiment, the elastic support balls on the inner bottom wall of the groove and the elastic support balls on the bottom surface of the support plate are distributed in a staggered and conflicting manner.

[0008] As a preferred implementation, a high temperature resistant rubber layer is fixedly connected to the surface of the elastic support ball.

[0009] As a preferred embodiment, a sliding opening communicating with the circular buffer groove is provided at the top of the groove, a high temperature resistant sealing layer is fixedly connected to the inner wall of the sliding opening, and the buffer column is in sliding contact with the high temperature resistant sealing layer.

[0010] As a preferred embodiment, a stud is fixedly connected at the center of the upper surface of the support plate, and a threaded groove matching the stud is opened at the center of the bottom of the buffer column.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The high-strength bottomless integral impact plate is provided with a circular buffer groove, a buffer column and a dispersion pit. When molten steel impacts the plate body, the molten steel first impacts the buffer column, and the impact force of the molten steel is dispersed by the buffer column. At the same time, the dispersion pit can disperse and absorb the impact of the molten steel. The dispersed molten steel is further unloaded after being guided by the inner wall of the circular buffer groove, thereby improving the impact resistance of the impact plate.

[0013] The high-strength bottomless integral impact plate is provided with a support plate and an elastic support ball. When the buffer column is impacted, the buffer column will drive the support plate to move downward, so that the support plate cooperates with the bottom wall of the groove to squeeze the elastic support ball, and the elasticity of the elastic support ball is used to buffer the impact force, thereby reducing the impact on the buffer column and extending the life of the buffer column.

Through the arrangement of the circular buffer groove 2, the buffer column 5 and the dispersion pits 6, when molten steel impacts the plate body 1, the molten steel first impacts the buffer column 5, and the impact force of the molten steel is dispersed by the buffer column 5. At the same time, the dispersion pits 6 can disperse and absorb the impact of the molten steel, and the dispersed molten steel is further unloaded after being guided by the inner wall of the circular buffer groove 2, thereby improving the impact resistance of the impact plate.

Through the arrangement of the support plate 4 and the elastic support balls 7, when the buffer column 5 is impacted, the buffer column 5 will drive the support plate 4 to move downward, so that the support plate 4 cooperates with the inner bottom wall of the groove 3 to squeeze the elastic support balls 7, and the elasticity of the elastic support balls 7 is used to buffer the impact force, thereby reducing the impact on the buffer column 5 and extending the life of the buffer column 5.
