Problems solved by technology

Although the above-mentioned technical solution can realize the accurate positioning of the seat brick, because it sets threaded holes on the bottom shell of the ladle to match the above-mentioned fixing bolts to fix the positioning plate, after the fixing bolts are matched with the threaded holes, through the positioning plate and the cylinder The positioning of the ring, the block cannot move horizontally
[0005] The locator disclosed in the above-mentioned prior art has the following defects when it is used for positioning the tundish seat brick: the tundish has multiple nozzles, and after the nozzles are installed in the seat brick, it is necessary to manually pull the wire to check whether the distance between adjacent nozzles is correct. At this time, once it is found that the distance between the centerlines of one or more adjacent nozzles does not meet the requirements, since the block is completely fixed and cannot move horizontally, it is impossible to directly align the nozzles with deviations in distance, and it is necessary to re-align the nozzles. The disassembly of the fixed block cannot realize the continuous operation of vertical positioning and horizontal alignment, which leads to repeated and cumbersome positioning procedures; moreover, since the cylindrical ferrule is integrated with the positioning plate and the diameter of the upper and lower parts is the same, this requires the block The diameter and shape of the hole are consistent with the diameter and shape of the outlet of the tundish, otherwise it cannot be installed. The outlet and the hole of the seat brick are both cylindrical and have the same diameter. In actual use, in order to meet different needs, the shape of the nozzle is diversified. Therefore, the shape of the block hole is also diversified. For example, the block hole is often required to be in an inverted conical shape. The positioning of block blocks with different block holes is especially not suitable for the positioning of block blocks with special-shaped block holes, and its universality is poor; Reduce the strength of the ladle bottom shell to a certain extent

Embodiment 1

[0044] This embodiment provides a continuous casting tundish seat brick positioning assembly. Here, it is necessary to explain the continuous casting tundish first. Several steel shell through holes 51 need to be opened on the steel shell 5 at the bottom of the continuous casting tundish. The seat brick 6, the seat brick 6 is used to fix the tundish nozzle. In view of the process requirements, several tundish nozzles need to be located on the same straight line, and the centerlines of adjacent tundish nozzles need to meet specific distance requirements. In this implementation In the example, the distance between the centerlines of adjacent tundish nozzles needs to meet the requirement of 1600mm. In order to meet the above distance between adjacent tundish nozzles, it is necessary to first make the distance between the centerlines of the central through holes 61 of adjacent block blocks 6 The distance between them satisfies 1600mm. The positioning assembly provided in this embod...

Embodiment 2

[0054] This embodiment provides a method for positioning a continuous casting tundish block using the tundish block positioning assembly of Embodiment 1 of the present invention, which specifically includes the following steps:

[0055] 1) Place the seat brick 6 on the upper part of the steel shell through hole 51 of the tundish steel shell 5;

[0056] 2) Insert the mating part 12 of the seat brick mating connector 1 into the central through hole 61 of the seat brick 6 so that the center lines of the two coincide after the two are matched, and make the center line of the central through hole 61 communicate with the steel shell. The centerlines of holes 51 are approximately aligned;

[0057] 3) Sleeve the positioning ring 2 on the connecting part 13 that coincides with the center line of the mating part 12, and fix the positioning ring 2 and the connecting part 13 through the fixing piece, and the center line of the positioning ring 2 and the center of the connecting part 13 l...

Abstract

The invention provides a continuous casting tundish brick cup positioning assembly and a positioning method. A brick cup is jointly positioned by a brick cup cooperation connecting piece, a brick cup positioning fixed piece and a positioning rod, so that the center line of the brick cup coincides or is in parallel with the center line of a steel shell through hole to realize the basic positioning of the vertical direction of the brick cup; in addition, the brick cup positioning fixed piece has a special gap after being cooperated with the steel shell through hole; under the action of the positioning rod, the brick cup, the brick cup cooperation connecting piece and the brick cup positioning fixed piece are used as a whole to move along the length direction of a tundish, so that a required distance between center lines of adjacent brick cups is achieved so as to realize the horizontal leveling of the brick cup.

Description

technical field [0001] The invention belongs to the metallurgical industry of iron and steel, and specifically relates to a continuous casting tundish seat brick positioning component and a positioning method for positioning the position of the seat brick and then the position of the tundish nozzle in the production of special steel. Background technique [0002] In the iron and steel metallurgy industry, there are generally two methods of solidification and forming of high-temperature molten steel: die casting (casting high-temperature molten steel into ingots, which are processed into billets by blooming mills or forging presses) and continuous casting (directly pouring high-temperature molten steel into continuous casting billets). , and the implementation of continuous casting can increase the metal yield and reduce production costs, so it is widely used. [0003] The continuous casting machine is a machine that directly casts liquid steel into solid billet, which includ...
