Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See Fig. 1～Fig. 3, a kind of high pressure water descaling device produced for high-quality thin specification steel plate, constitute including thick de-scaling upper header 2, thick de-scaling lower collector pipe 7, essence de-scaling upper header 3, essence de-scaling lower collector pipe 6, intermediate duct 9 and control valve group, before and after wherein thick de-scaling upper header 2 and essence de-scaling upper header 3 are mounted side by side on milling train 1 respectively in guide and guard 4, essence de-scaling lower collector pipe 6 and thick de-scaling lower collector pipe 7 are separately mounted to the lower section of feeding roller 5, and are connected with de-scaling control valve group by intermediate duct 9.
Described de-scaling control valve group is according to controlling requirement, totally 8 groups, include on entrance wide de-scaling control valve group 10, entrance narrow de-scaling control valve group 11, entrance smart de-scaling control valve group 15 in essence de-scaling control valve group 13 under essence de-scaling control valve group 12, entrance, outlet lower essence de-scaling control valve group 14, outlet, export narrow de-scaling control valve group 16 and export wide de-scaling control valve group 17.
