The invention discloses a method and a device for avoiding working fluid backflow. According to the method, during metal plate rolling, compressed air on the outlet side of a cold mill is opened for blowing so as to block working fluid flowing back to the outlet side of the cold mill, and simultaneously a plugging injection beam and a roll injection beam which are arranged on the inlet side of the cold mill are started so as to lead a plurality of nozzles arranged on the plugging injection beam with a certain angle to spray working fluid to block the working fluid flowing back to the inlet side of the cold mill. When the preset length of the processed metal plates is remained, the nozzles of the plugging injection beam and the roll injection beam stop spraying working fluid, and compressed air on the inlet side of the cold mill is opened for blowing so as to block the working fluid remained on the metal plates from flowing back to the inlet side. By aid of the method and the device of the embodiment, the working fluid with certain quantity of motion is used for blocking backflow working fluid, the quality of the processed metal plates cannot be affected, simultaneously use amount of the compressed air is greatly reduced, and resource waste is reduced.
Description
Technical field [0001] The invention relates to the field of metal processing, and more specifically, to a method and device for preventing backflow of processing fluid. Background technique [0002] In the process of rolling the metal sheet by the cold rolling mill, the roll spray beams on the inlet and outlet sides of the cold rolling mill spray working fluid to the rolls of the cold rolling mill to achieve the purpose of lubricating or cooling the cold rolling mill , To ensure the normal rolling work of the cold rolling mill. In the above process, the problem of working fluid backflow often occurs. The working fluid backflow refers to the phenomenon that the working fluid flows to the inlet and outlet sides of the cold rolling mill along the surface of the processed metal sheet on the conveyor. In the field of metal processing, the problem of working fluid backflow greatly affects the quality of processed metal products. [0003] In order to solve the above problems, the prior...
