Strip steel surface clearing device and method

The invention relates to a strip steel surface clearing device and method and belongs to the technical field of cold rolling production devices in the metallurgy industry. According to the technical scheme, the strip steel surface clearing device comprises a laser generator, multiple laser heads and multiple groups of laser beams, the multiple groups of laser beams are arranged on the upper side and the lower side of strip steel and arranged in the operation direction of the strip steel, each group of laser beams comprise multiple laser heads arranged side by side, and the laser heads are connected with the laser generator in a controlled manner. The laser generator transmits the generated lasers to the laser heads, and clearing of the surface of the strip steel is achieved through the laser beams emitted by the laser heads. The strip steel surface clearing device and method have the beneficial effects that the lasers generated by the laser generator are used for cleaning the surface of a hot-rolled steel str
