[0002] The domestic use of oxygen top-blown converter steelmaking is carried out at a high temperature of more than 1600℃. The converter body is generally composed of three parts: the furnace cap, the furnace shell, and the furnace bottom. In order to extend the service life of the metal shell and the furnace lining of the furnace cap, a circular furnace mouth is generally provided on the top of the furnace cap, so that the oxygen gun can be inserted to discharge the furnace gas and pour the slag during work. In order to protect the furnace mouth, circulating water is generally used to cool the furnace mouth. The current furnace mouth is made of two identical furnace mouth boxes. An S-shaped cooling water channel is formed by the staggered welding of baffles inside the box to connect with the water pipe inside to form a water cycle. However, the existing furnace mouths are welded together by multiple components, and the overall structure has too many welding points. After long-term use, the probability of leakage problems is greatly increased, and it is difficult to find the leakage points; frequent remedial work is required, and the cost of manual maintenance is high; at the same time, the furnace mouth is in a high-temperature working environment, which greatly increases the difficulty of maintenance, and the maintenance environment is harsh, and there are safety hazards for maintenance personnel; in addition, the overall structural stability of the existing furnace mouth is poor, so the high temperature resistance is poor and it is easy to deform. However, when replacement is needed, the entire set needs to be replaced, which greatly increases the cost of use. Utility Model Content

[0016] 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 part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0019] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0020] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.
[0021] The terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.
[0022] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0023] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute accuracy, but can have certain deviations. For example, "roughly equal to" does not only mean absolute parallelism. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal to" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.
