Bar finishing area noise reduction method

The invention relates to the technical field of steel rolling production and particularly relates to a bar finishing area noise reduction method. The method comprises the following steps of 1) determining a cover plate causing resonance in a noise generation area; and 2) arranging a damping layer on the bottom surface of the cover plate; the damping layer is made of a butyl rubber damping plate, and thickness of the butyl rubber damping plate is 3 mm. Aiming at a phenomenon of noise caused by cover plate resonance, a damping sound insulation and vibration stopping method is adopted, the damping layer is arranged on the bottom surface of the cover plate, the vibration frequency of the cover plate is reduced through the damping layer, noise transmission can be effectively reduced due to the fact that the density of the damping layer is large, the working condition that noise generated in the production process of a bar finishing area exceeds the standard is fundamentally solved, and noise treatment is carried o
