Embodiment Construction

[0025] The embodiment of the present application provides a method for controlling the liquid level fluctuation of the continuous casting mold to solve the technical problem of unsatisfactory control effect of the liquid level fluctuation in the continuous casting mold in the prior art; to improve the ripple suppression efficiency and simplify the operation process technical effect.

[0026] In order to solve the above technical problems, the general idea of ​​the technical solution provided by the embodiment of the present application is as follows:

[0027] A method for controlling liquid level fluctuations in a continuous casting mold, comprising:

[0028] Putting mold slag on the liquid surface of the crystallizer to form a mold slag layer;

[0029] resting a leveling board on the mold powder layer;

[0030] Wherein, the contact surface between the leveling plate and the mold slag layer is plane, and is kept on the mold slag layer.

[0031] From the above content, it ca...

Abstract

The invention belongs to the technical field of steelmaking and discloses a method for controlling fluctuation of the liquid level of a continuous casting crystallizer. The method includes the steps that covering slag is put to the liquid level of the crystallizer to form a covering slag layer. A flat plate is laid on the covering slag layer. The face, in contact with the covering slag layer, of the flat plate is a plane, and the flat plate is kept located on the covering slag layer and does not sink into the covering slag layer. The method is directly used for solving the problem that fluctuation of the liquid level in the crystallizer is too large; due to the cooperation of the covering slag layer and the flat plate, manners of buffering and gradual weakening are achieved, fluctuation is inhibited in a forced manner, efficiency is high, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a method for controlling liquid level fluctuations in a continuous casting crystallizer. Background technique [0002] During the continuous casting process, the crystallizer liquid level fluctuates greatly, which will have many adverse effects on the quality of the continuous casting slab and production control. The specific manifestations are: the liquid level fluctuation will directly lead to mold slag being involved in the steel slab, which will cause the surface quality of the slab to deteriorate; the liquid level fluctuation will cause longitudinal cracks on the surface of the slab; the crystallizer liquid level fluctuation will affect the meniscus liquid steel. solidification. [0003] The causes of large fluctuations in the liquid level of the mold include at least: when the molten steel enters the mold from the tundish, non-metallic inclusions such as aluminum oxide...
