Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls, and particularly relates to a tundish continuous casting retaining wall which is convenient to replace. Background Technique

[0002] Continuous casting technology plays a crucial role in iron and steel production. The tundish continuous casting retaining wall of its continuous casting device is an intermediate container for reducing pressure, stabilizing pressure, maintaining the stability of the continuous casting process, evenly distributing molten steel to each mold, and realizing multi-furnace continuous casting. During the use of the tundish, the slag line part of the retaining wall is eroded and disappears in the later stage, or holes appear at the slag line position for slag passing, losing the slag blocking function. The retaining wall needs to block slag throughout the process, which is an effective means to ensure the cleanliness of the molten steel inside the tundish. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tundish continuous casting retaining wall which is convenient to replace, so as to solve the problems put forward in the above background technique.

[0006] A retaining wall is movably installed on the surface of the third impact box. Different from the traditional retaining wall that cannot be replaced during the continuous casting of the tundish, when the retaining wall is damaged in the later stage, slag in the impact area will enter the casting area, which will affect the cleanliness of the molten steel. At the same time, replacing the retaining wall during the continuous casting of the tundish is an effective measure to ensure the cleanliness of the molten steel in the later stage of the continuous casting of the tundish. By using hoisting to replace the retaining wall, after use, the used retaining wall can be directly hoisted and removed by a crane, and the subsequent new retaining wall can also be hoisted by a crane, which is convenient for installation and replacement to improve the use efficiency.

[0007] A further improvement of the technical solution of the utility model lies in that: the first impact box includes a first box body, a connecting rod is fixedly installed on one side of the first box body, and a clamping groove is opened on the front surface of the first box body. By opening the clamping groove, it is convenient to cooperate with the installation of the third impact box.

[0008] A further improvement of the technical solution of the utility model lies in that: the second impact box includes a second box body movably installed on one side of the first box body, a connecting groove is opened on one side of the second box body, and a clamping groove identical to that of the first box body is opened on the front surface of the second box body. By opening the connecting groove, it is convenient to cooperate with the connecting rod for the assembly of the first box body.

[0009] A further improvement of the technical solution of the present utility model lies in that: the main package cover includes a main package cover body movably installed on the top surfaces of the first box body and the second box body.

A clamping rod is fixedly installed on the surface of the third box body. The provision of the clamping rod facilitates the assembly of the third box body in a movable manner and also facilitates disassembly and replacement in the later stage.

[0011] A further improvement of the technical solution of the present utility model lies in that: the auxiliary package cover includes an auxiliary package cover body movably installed on the top surface of the third box body. A middle notch is formed on the surface of the auxiliary package cover body.

[0012] A further improvement of the technical solution of the present utility model lies in that: the second box body and the first box body are movably connected through a connecting groove and a connecting rod, and the third box body is movably connected to the first box body and the second box body through a clamping rod and a clamping groove. By providing the clamping groove and the connecting groove on the box body and installing the connecting rod and the clamping rod at the same time, effective mutual movable connection can be achieved, thereby facilitating reduction of the occupied area for transportation of the divided box bodies and also facilitating individual disassembly and replacement in the later stage when damaged.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0014] 1. The present utility model provides a tundish continuous pouring dam that is easy to replace. Different from traditional dams that cannot be replaced during the continuous pouring of the tundish, slag in the impact zone will enter the pouring zone after the dam is damaged in the later stage, which will affect the cleanliness of the molten steel. At the same time, replacing the dam during the continuous pouring of the tundish is an effective measure to ensure the cleanliness of the molten steel in the later stage of the continuous pouring of the tundish.

[0015] 2. The present utility model provides a tundish continuous pouring dam that is easy to replace. By using hoisting to replace the dam, the used dam can be directly hoisted and removed by a crane after use, and the subsequent new dam can also be hoisted by a crane, which is convenient for installation and replacement to improve the use efficiency.

[0016] 3. The present utility model provides a tundish continuous pouring dam that is easy to replace. By providing a clamping groove and a connecting groove on the box body and installing a connecting rod and a clamping rod at the same time, effective mutual movable connection can be achieved, thereby facilitating reduction of the occupied area for transportation of the divided box bodies and also facilitating individual disassembly and replacement in the later stage when damaged.
