Description

Technical Field

[0001] The utility model belongs to the technical field of iron oxide scale cleaning of steel, and in particular relates to an iron oxide scale cleaning device for a detection point of a hot rolling speed meter. Background Art

[0002] At present, the hot rolling production line uses laser velocimeter to detect the speed of the strip. Due to various reasons, it is impossible to eliminate the oxidized iron scale of the strip. The irregular shaped oxidized iron scale changes the laser reflection angle of the laser velocimeter, causing the laser velocimeter to be unable to receive the detection laser signal, resulting in a drop in speed (zero speed), which directly affects the cutting of the strip. In severe cases, the steel is directly stuck and the rolling is stopped. Therefore, accurate detection by the velocimeter is an indispensable condition for the stable operation of the production line. At present, the fan is used to blow the ambient water vapor, which consumes electricity and has a general effect. The oxidized iron scale on the surface of the strip has always troubled the on-site electrical maintenance personnel.

[0003] The prior art discloses an application number CN201921453610.1, which is called an improved device for cleaning the surface oxide scale of a continuous casting billet, and includes a steel brush, a fixing screw and a fixing structure; two steel brushes with steel wires are installed on the fixing structure above the roller table where the continuous casting billet runs by using fixing screws, and the steel brushes are distributed in a cone shape in the opposite direction of the running of the continuous casting billet. The above prior art has the characteristics of simple operation, wide application of steel types, and low cost.

[0004] However, the above-mentioned prior art uses a steel brush with a steel wire to scrape off the oxidized iron scale. Due to the influence of the transmission belt speed, the steel brush with a steel wire cannot fully treat the oxidized iron scale, which directly affects the cutting of the strip head and tail. In severe cases, the steel is directly stuck and the rolling is stopped.

[0005] In view of the above factors, a hot rolling speed meter detection point iron oxide scale cleaning device is specially designed. Through the high-pressure water gun and the compressed air main pipe connected to the compressed air pipeline on site, relatively equal pressure compressed air is provided to several nozzles, which effectively solves the influence of the hot rolling line strip iron oxide scale on the speed meter detection.
