Problems solved by technology

[0006] The third type: using a skateboard to block slag, which is characterized by great difficulty in production and replacement, difficult maintenance and high cost, but the effect of slag blocking is very good
If the position of the taphole is too high, the slag blocking ball cannot reach the steel tapping hole; or if there is a pit around the tapping hole, the slag blocking ball can only rotate at this position when it is rotated into the pit, and the slag blocking effect cannot be achieved.
If the slag-stopping cone is used for slag-stopping, due to the small space for small furnaces, the nearly 6-meter-long slag-stopping cone hydraulic device cannot meet the requirements.

Embodiment Construction

[0030] The specific implementation of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0031] Such as figure 2 , image 3 The structure shown is the converter slag retaining device of the present invention, which is a simple slag retaining cone structure, which achieves the slag retaining effect of the normal slag retaining cone. It includes making the structure and density of the slag-stopping cone of the main body, making the push rod of the slag-stopping cone, and determining the position of the slag-stopping cone. Its structure includes slag retaining cone 2 and push rod 5 . Its overall structure is conical.

[0032] In order to solve the problems existing in the prior art and overcome its defects, realize th...

Abstract

The invention discloses a converter slag blocking device. The converter slag blocking device comprises a slag blocking cone (2) and a pushing rod (5). The large end, close to the taper of the slag blocking cone, of the slag blocking cone (2) is provided with two grooves (8) which are symmetric about the axis of a slag blocking cone body and are parallel to each other. The invention further discloses a method for operating the converter slag blocking device. According to the technical scheme, the converter slag blocking device is simple in structure, convenient to manufacture, low in cost, free of maintenance cost and position influence, good in slag blocking effect and suitable for being used for slag blocking of any converter.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry production, and relates to steelmaking production process equipment for steelmaking. More specifically, the present invention relates to a converter slag blocking device. In addition, the present invention also relates to the operation method of the slag blocking device. Background technique [0002] The slag blocking process of the converter is to ensure that the slag is not dropped in the later stage of tapping the converter, and to prevent the generation of molten steel waste caused by the slag returning to phosphorus. [0003] The current slag blocking process equipment is divided into three types: [0004] The first one: use slag blocking balls, which are characterized by simple production and addition methods and low cost, but the slag blocking effect is not good; [0005] The second type: use the slag blocking cone, which is characterized by requiring a certain amount of e...
