[0002] At present, the mandrel cooling water ring of the mandrel trolley of the pipe rolling mill, in the production process, the cooling water ring cools the mandrel after rolling the pipe. The mandrel was originally cooled by water and then entered the graphite spraying ring for graphite spraying. Improve the quality of the inner surface of the rolled tube, but due to the high-pressure water cooling, the mandrel cannot be completely dried, and water enters the graphite spraying equipment, resulting in poor graphite spraying quality during the graphite spraying process, and water enters the graphite recovery pool , reducing graphite solubility

The invention discloses a pipe mill graphite core rod water blowing device. The device comprises a pipe mill core rod. A cooling water ring and a graphite spraying ring are arranged on the front segment and the rear segment of the pipe mill core rod correspondingly, the cooling water ring is connected into a cooling water system, the graphite spraying ring is connected into a graphite spraying system, at least one high-pressure water blowing ring is arranged between the cooling water ring and the graphite spraying ring, multiple air openings are formed in the high-pressure water blowing ring,and the high-pressure water blowing ring is connected into a high-pressure air drying system. According to the pipe mill graphite core rod water blowing device, the high-pressure water blowing ring isadditionally arranged between the cooling water ring and the graphite spraying ring, before the core rod enters in graphite spraying, water on the surface of the core rod can be subjected to air drying, bringing in of water can be effectively reduced, spraying quality of graphite is improved, the inner surface quality of a steel pipe is improved, and the use amount of graphite is reduced.
Description
technical field [0001] The invention relates to a pipe rolling mill, in particular to a water blowing device for a graphite mandrel of a pipe rolling mill. Background technique [0002] At present, the mandrel cooling water ring of the mandrel trolley of the pipe rolling mill, in the production process, the cooling water ring cools the mandrel after rolling the pipe. The mandrel was originally cooled by water and then entered the graphite spraying ring for graphite spraying. Improve the quality of the inner surface of the rolled tube, but due to the high-pressure water cooling, the mandrel cannot be completely dried, and water enters the graphite spraying equipment, resulting in poor graphite spraying quality during the graphite spraying process, and water enters the graphite recovery pool , reducing the solubility of graphite. Contents of the invention [0003] The purpose of the present invention is to provide a water blowing device for graphite mandrels of pipe mills, ...
