Abstract
The invention discloses a purging inspection device of a continuous casting three-machine three-flow spraying system. The device comprises a second-cold water main pipe, a nitrogen main pipe, a first-flow spraying system, a second-flow spraying system and a third-flow spraying system, wherein one end of the second-cold water main pipe is connected to a second-cold water pipe network, and the other end is respectively connected to the first-flow spraying system, the second-flow spraying system and the third-flow spraying system through three second-cold water branch pipes; four spraying pipes are respectively arranged in the first-flow spraying system, the second-flow spraying system and the third-flow spraying system; the second-cold water branch pipes are communicated with corresponding four spraying pipes; and one end of the nitrogen main pipe is connected to a nitrogen pipe network, and the other end is respectively connected to each spraying pipe through metal hoses. The purging inspection device of the continuous casting three-machine three-flow spraying system can effectively drain water remained in the spraying pipes and nozzles to largely reduce the formation of incrustations and to effectively reduce the blockage rate of the nozzles.
