Problems solved by technology

For large-section continuous casting machines, the quick change of the tundish generally adopts the high liquid level quick change of the mold, the submerged nozzle is inserted into the molten steel to start casting, and the billet shell shrinks during the quick change process, especially for steel types with a large amount of alloy. The billet shell shrinks severely, and the opening becomes smaller. If the submerged nozzle cannot be inserted into the molten steel, the quick change will fail
In addition, the rapid shrinkage of the billet shell in the mold during quick change makes the fusion of the billet shell and molten steel in the mold uneven after pouring, and it is easy to cause joint breakout

Embodiment Construction

[0012] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The invention discloses a supporting piece for preventing rapid shrinkage of the billet shell in the crystallizer. The supporting piece is especially suitable for preventing the rapid shrinkage of the billet shell in the crystallizer during the quick change process of the large-section continuous casting tundish. The specific structure is: the supporting piece includes two weldments, the two weldments are welded and fixed together by a connecting beam 3, and a hook 2 is provided on one side of each weldment. The weldment selected here is trapezoidal weldment 1.

[0013] The invention also discloses a method for preventing rapid shrinkage of the slab shell in the crystallizer, the method is applied to the support, and the method includes the following steps:

[0014] 1) When the old tundish is raised to a high position and the pouring posit...

Abstract

The invention discloses a supporting piece used for preventing fast shrinkage of an inner shell of a crystallizer and an application method thereof. The supporting piece used for preventing the fast shrinkage of the inner shell of the crystallizer comprises two welding elements, wherein the two welding elements are welded and fixed together by virtue of a connecting beam, and a hook is arranged at one side of each welding element. The problem that the inner shell of the crystallizer shrinks fast in a quick large-section continuous casting tundish changing process can be solved by combining the supporting piece used for the fast shrinkage of the inner shell of the anti-crystallization device and matching the application method disclosed by the invention.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a support member for preventing rapid shrinkage of a slab shell in a crystallizer and a method for preventing rapid shrinkage during the quick change process of a continuous casting tundish. Background technique [0002] The operation process of quick-change tundish further excavates the working time of the continuous casting machine, improves the working efficiency of the continuous casting machine, significantly increases the daily output of the continuous casting machine, and has a significant effect of energy saving and consumption reduction. For large-section continuous casting machines, the mold high liquid level quick change is generally used for quick change of the tundish. The submerged nozzle is inserted into the molten steel to start casting. The billet shell shrinks during the quick change process, especially for steel types with a large amount of alloy...
