Description

Technical Field

[0001] This utility model belongs to the field of continuous casting machinery technology, and in particular relates to a novel seat device for a tundish car. Background Technology

[0002] The tundish car used in the billet continuous casting machine is an important piece of equipment in the entire continuous casting system. The position of the tundish nozzle is directly related to the quality of the billet during tundish casting, and the tundish car's tundish mounting device is one of the important factors in ensuring the nozzle position.

[0003] The existing tundish mounting system uses cylindrical pins. However, because the tundish expands at high temperatures, using too many rigid guides like cylindrical pins can cause structural deformation due to thermal stress, leading to jamming or stress concentration. Therefore, only one positioning reference is currently used, with the other three corners forming planar supports that only bear vertical loads and do not restrict horizontal displacement. As a result, each time the tundish is mounted, the mounting time is longer due to the limited positioning references, and the collisions during hoisting can damage the equipment. Furthermore, if the tundish position deviates significantly, subsequent adjustments will be affected, leading to incomplete adjustments, which will affect the alignment of the tundish nozzle and the quality of the cast billet. Summary of the Invention

[0004] The purpose of this invention is to provide a novel tundish seat device. By designing a cylindrical pin and a positioning sleeve on the tundish body, it can play a primary positioning role at one corner, achieving forced centering. Through the design of two guide frames and a guide plate on the tundish body, it can serve as auxiliary positioning points at the other two corners of the tundish body for auxiliary positioning and guidance. The last corner serves as a free end for support, which can ensure the stability and accuracy of the tundish seat process, guarantee the quality of the subsequent casting billet, and improve the tundish seat efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a novel seat device for a mid-sized car, comprising a mid-sized body, a seat platform, and two guide frames;

[0007] A cylindrical pin is fixed at one corner of the top of one side of the seat cushion platform, and the two guide frames are respectively fixed at two corners of the top of the other side of the seat cushion platform;

[0008] The guide frame includes a set of symmetrically arranged guide plates, each guide plate consisting of a lower vertical section and an upper inclined section connected in sequence, with a V-shaped opening formed between the upper inclined sections of the two guide plates;

[0009] The bottom of the guide plate is provided with a mounting base that is fixed to the seat platform, and a set of reinforcing ribs are provided between the outer side of the guide plate and the mounting base;

[0010] A positioning sleeve that mates with a cylindrical pin is fixed to the outer side of one corner of the middle package body, and the bottom end of the positioning sleeve is provided with a conical sleeve end;

[0011] Guide discs are fixed to the outer sides of the two corners on the other side of the middle package, and the bottom of the guide discs is provided with arc-shaped segments with successively decreasing diameters.

[0012] Furthermore, one of the guide discs and the positioning sleeve is disposed on the outer side of the same end of the middle package body, and the other guide disc is disposed at the outer corner of the other end of the middle package body.

[0013] Furthermore, the distance between the lower vertical sections of the two guide plates on the guide frame is greater than the outer diameter of the guide disc, and the excess distance forms a thermal expansion clearance interval.

[0014] Furthermore, the mounting base of the guide plate near the edge of the seat cushion is an inverted L-shaped plate that covers the top edge of the seat cushion, while the mounting base of the guide plate away from the edge of the seat cushion is a horizontal plate structure.

[0015] Furthermore, a lower extension section is formed at the bottom of the reinforcing rib plate of the guide plate near the edge of the seat platform. The bottom edge of the lower extension section extends beyond the bottom edge of the mounting base, and the area of ​​the lower extension section extending beyond the mounting base is welded and fixed to the outer side of the seat platform.

[0016] Furthermore, the height of the guide frame is lower than the height of the cylindrical pin.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, through the design of a cylindrical pin and the positioning sleeve on the tundish body, can play a primary positioning role at one corner, achieving forced centering. Through the design of two guide frames and a guide plate on the tundish body, it can serve as an auxiliary positioning point at the other two corners of the tundish body for auxiliary positioning and guidance. The last corner serves as a free end for support, which can ensure the stability and accuracy of the tundish setting process, ensure the quality of the subsequent casting billet, and improve the tundish setting efficiency.

[0019] 2. This utility model uses a guide frame for auxiliary guidance. Compared with the positioning of cylindrical pins, the middle package is automatically positioned and guided by gravity, which facilitates the rapid adjustment of the position of the middle package. At the same time, the distance between the two guide plates is greater than the outer diameter of the guide plate, which can provide clearance for thermal expansion and avoid jamming or deformation problems.
