Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a cold rolling mill, which comprises a shell 1, an inlet 2, an outlet 3 and a rotating wheel 4, wherein a cleaning device and a guiding device are arranged in the cold rolling mill; the guiding device is communicated with a high-pressure air pipe 5. Thereby blowing the steel in the cold rolling mill at high pressure and cleaning the steel. The cleaning device is used for contacting the surface of the steel, so that scrap iron and oil stains are cleaned.

The cleaning device comprises hydraulic telescopic rods 6 arranged at two sides in the shell; the hydraulic telescopic rods 6 are connected with cleaning plates 7, and the two cleaning plates 7 are arranged oppositely; the surface of the cleaning plate 7 is provided with a cleaning brush 8.
