Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling, in particular to a strip steel plate surface leveling liquid blowing device. Background Art

[0002] The leveling machine is an important equipment for restoring the mechanical properties of the strip after annealing. During the production process, the leveling liquid spots will affect the quality of the strip. The edge blowing device of the leveling machine can only blow the edge of the strip. During the edge blowing process, the leveling liquid blown off splashes everywhere, and part of it falls back on the surface of the strip after flattening, forming smaller dot-shaped leveling liquid spots. Since there is no blowing in the middle of the strip, the leveling liquid remaining on the plate surface will cause problems such as roller sticking and straightening and stamping in subsequent production, affecting the processing and production of the strip. In order to solve the problem of leveling liquid blowing residue, a new type of strip surface leveling liquid blowing device is needed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-3 The device for blowing liquid to level the surface of a steel plate shown in the figure comprises a first fixing frame 1 arranged on the top of the steel plate surface and a second fixing frame 2 arranged on the bottom of the steel plate surface, a first blowing pipe 3 is hingedly connected to one side of the first fixing frame 1, and a second blowing pipe 4 is arranged on one side of the second fixing frame 2;

[0018] Specifically, an inclined nozzle 301 for spraying compressed air is symmetrically arranged on the outer side of the first purge pipe 3, and a horizontal nozzle 302 is arranged on the outer side of the first purge pipe 3 and located on the outer side of the inclined nozzle 301;

[0019] It should be noted that the first purge pipe 3 and the second purge pipe 4 are both provided with an equalizing chamber inside to ensure uniform airflow of each nozzle. There are 14 inclined nozzles 301 and 1 horizontal nozzle 302. The horizontal nozzle 302 blows the leveling liquid remaining in the middle of the board surface to the edge. The symmetrically distributed inclined nozzles 301 of the first purge pipe 3 blow the edge of the board surface and the leveling liquid blown from the middle to the outside of the board surface. The inclined nozzles 301 and the center line of the board surface present a spatial 60° purge.

[0020] Specifically, a plurality of elevation nozzles 401 are arranged on the top of the second purge pipe 4, and the number of the elevation nozzles 401 on the top is 15, and the arrangement form is the same as the arrangement form of the nozzles on the outside of the first purge pipe 3.
