Description

Technical Field

[0001] The utility model relates to the field of steelmaking equipment, in particular to a device for reinforcing a converter skirt. Background Art

[0002] The converter of Bengang Plate Steelmaking Plant has been upgraded and renovated for many times. The converter capacity has been expanded without changing the converter plant framework, and the 120T converter has been upgraded to a 180T converter. As a result, the converter capacity is relatively small, and splashing problems are very likely to occur during blowing.

[0003] The existing converter skirt is welded to the furnace body bracket. The bracket is arranged on the furnace body by angle steel according to the size. When welding, the long side of each slag baffle is welded on the top of the bracket. The converter splashes seriously due to the small furnace volume ratio, and the splashed red slag or molten steel will adhere to the skirt. The skirt is repeatedly affected by extreme cold and hot conditions, and it is distorted and deformed. The connection welds are open, causing the converter smoke hood or surrounding baffles to be scraped. Therefore, it needs to be handled frequently in the later stage of the furnace service. Utility Model Content

[0004] The utility model provides a device for reinforcing a converter skirt, which solves the problems of deformation of the existing skirt and failure of scraping the converter smoke hood or surrounding baffles.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device for reinforcing a converter skirt comprises a first reinforcing plate and a second reinforcing plate, wherein the first reinforcing plate and the second reinforcing plate are mounted on two adjacent converter skirts by bolts, wherein the first reinforcing plate is vertically mounted on the converter skirt, and the second reinforcing plate is horizontally mounted on the converter skirt, and the first reinforcing plate is arranged on the upper part of the converter skirt relative to the second reinforcing plate.

[0007] Furthermore, the first reinforcement plate has a width of 400 mm and a length of 1500 mm.

[0008] Furthermore, the second reinforcement plate has a width of 400 mm and a length of 800 mm.

[0009] Furthermore, the reinforcement plate is provided with openings every 400 mm at a position 100 mm away from the edges on both sides.

[0010] Furthermore, the diameter of the opening is 25 mm.

[0011] Furthermore, through holes are provided at relative positions of the two adjacent furnace skirts, and the diameter of the through holes is equal to the diameter of the opening.

[0012] Furthermore, the bolt is an M24 bolt.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a first reinforcement plate and a second reinforcement plate. During the production process, when the converter skirt is subjected to high-temperature baking and the impact of slag removal by a furnace car, the reinforcement plates can enhance the deformation resistance of the converter skirt and delay the deformation of the skirt, thereby extending the service life of the converter skirt, reducing the downtime and equipment maintenance costs, and reducing the need to replace the skirt during the service life of the furnace.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation.
