Tool for adjusting angle of nozzle of rolling mill

The utility model discloses a tool for adjusting an angle of a nozzle of a rolling mill, which belongs to the technical field of cold rolling strip rolling; the tool comprises a base, two side plates, clamping grooves and a clamping sheet, wherein the two side plates are respectively fixed on two sides of the base; the clamping groove is formed in one side plate; and more than one clamping grooves are formed in the other side plate. The clamping sheet is respectively inserted into the clamping grooves of the two side plates, so that the clamping sheet forms an angle with one side plate. According to the utility model, the clamping grooves with the corresponding angles on the two sides are connected with each other by the clamping sheet according to the adjusting angle needed by each nozzle and then aligned with the inclined degree of the nozzle; therefore, simplicity and convenience in operation, high efficiency and high accuracy of the adjusted angle of the rolling mill nozzle are achieved.
