Abstract

PURPOSE:To eliminate the waste of high pressure injection fluid and to prevent the abrasion of peripheral apparatus by changing the injection width of a header by the movement of the header body in its longitudinal direction. CONSTITUTION:In the case of removing the scale of a rolling material 40 of the smallest width, it is a nozzle 21b which is in alignment to the center C of the line, and a rotary valve 29A is held closed, 29B held opened and 29C held opened. Namely, the nozzles which are injecting fluid are the three pieces of 21a, 21b, 21c. Then, in the case of adapting this to a rolling material 41 of further greater width, a header body 20 is slided by the nozzle pitch. A pinion meshing with a rack rotates 90 deg., and the rotary valve 29A opens, 29B closes and 29C opens, so that highly pressurized water is filled in chambers 23, 24, and the highly pressurized water is injected only from five pieces of the injection nozzles 21a-21e. Thus, the injection width is changed arbitrarily for any width of the rolling materials simply by sliding the head body axially.
