Description
Technical Field
The utility model relates to an off-line centering device for a tundish submerged nozzle.
Background
The tundish of the continuous casting machine adopts the integral immersion nozzle, so that secondary oxidation can be prevented, and the occurrence of a casting flow flocculation phenomenon is reduced. If the centering installation precision of the integral immersed nozzle is not high, the nozzle can deviate from the center of the crystallizer and is close to the copper pipe wall of the crystallizer, so that the molten steel flow field in the crystallizer is uneven, the primary solidification and cooling uniformity is affected, casting blank bending and component segregation are caused, and the casting blank shell formation is affected to cause steel leakage accidents when serious, so that the integral immersed nozzle centering installation of the tundish is required to be high in precision. When the integral type water gap is installed, the water gap is inserted from a tundish water gap pocket brick, the water gap is fixed with the tundish after centering, casting is carried out, manual centering is mostly adopted at present, workers rely on self experience to perform centering operation, and water gap constructors are relied on to observe a line or draw a line method, but due to reasons of personnel skill level and the like, the water gap centering condition is difficult to guarantee, the deviation of the centering position and the insertion depth of the integral type water gap is large, and the quality of the obtained product is unstable.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a middle package immersion nozzle off-line centering device, includes centering board and support frame, be provided with a plurality of and the unanimous locating hole of mouth of a river external diameter size on the centering board, and a plurality of locating hole center is on same horizontal line centering board bottom is provided with a plurality of the support frame to every support frame all is located at two adjacent locating hole middle parts.
The utility model further defines the technical scheme that:
preferably, limiting plates are arranged on the front side and the rear side of the top of each supporting frame.
Preferably, a limiting hole is formed in the middle of each limiting plate, a nut is installed in each limiting hole, and a limiting screw is arranged in each nut.
Preferably, a transverse supporting plate is arranged between the supporting legs at the front side and the rear side of the supporting frame, so that the effect of stabilizing and reinforcing is achieved.
Preferably, universal wheels are arranged at the bottoms of the supporting legs of the supporting frames, so that the supporting frames can be moved conveniently.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has simple structure, can realize the centering of the off-line nozzle of the tundish, ensures the centering precision of the immersed nozzle, provides conditions for realizing continuous and quick replacement of the tundish, greatly improves the quality of casting blanks and greatly improves the yield of casting blanks; meanwhile, the centering device can effectively reduce the water gap centering installation difficulty of workers, shorten the quick change time of the tundish and avoid quality accidents and production accidents caused by water gap deviation.
