(Scissor & number of multi-segment light dryer 1 'supply rolling lubricant L (U for light cooling oil) to work report 52, 53, or work light H in the 1G segment constitutes 'or six segments of the composition - In the case of the case, the dry-pressure lubricating oil is supplied from the injection portion 15A disposed on the front side or the rear side of the light work. However, in the case of the 10-stage configuration and the 6-stage configuration, the diameters and work of the working light 52, 53 The diameters of the rolls 82 and 83 are different and the spatial condition of the periphery of each of the rolls is also changed. Therefore, when the configuration is 10 stages and 6 stages, the rolling lubricant 1 sprayed by the injection unit 150 is switched (adjusted). In the injection direction, as shown in Figs. 9 and 10, the injection portion 15A is provided with: a spray nozzle 52a that sprays the lubricating oil L toward the work roll 52; and a spray lubricant L under the work roll 53. The side nozzles 52b; and the injection angle adjusting mechanism 160 that can adjust the injection direction of the rolling lubricating oil L from each of the nozzles 152a, 152b. '320012 23 1332864

The injection angle adjustment mechanism 160 is composed of the following members, and includes: an upper side rotation plate 162a of the upper side nozzle 152a and a gear i62w of the upper side rotation plate 162a are disposed outward in the radial direction while the gear portion 1 62w is formed in a part of the outer circumference. The upper rotating plate 162a is rotated by the worm gear 1 64a in the circumferential direction; the lower side rotating plate 162b of the lower nozzle 152b is disposed outward in the radial direction while the gear 162w is formed in a part of the outer circumference; The gear 162W of the side rotation plate 162b rotates the lower rotation plate 162b to the lower side worm gear 丨 64b in the circumferential direction; the rotation shaft 165 of the upper side spur gear 164a and the lower worm gear 164b; and the rotation shaft 16 5 Motor 16 at one end. The rotation axes of the respective rotating plates 162a and 162b are oriented in the horizontal direction. Then, for example, as shown in Fig. 9, the upper side nozzle 152a faces the work roll 52, and the lower side nozzle 152b faces the work roll 53. The upper worm gear 1 64a is engaged with the gear 162w formed on the outer peripheral surface opposite to the upper side rotating plate 162a, and the upper side nozzle 152& holds the rotating shaft, and the lower side worm gear 164b is engaged with the gear 162w. The gear 16 is formed on the outer peripheral surface on the opposite side of the lower side rotating plate 126b, and the rotating shaft is interposed between the lower side nozzle 152b. When the support upper side helical gear 16 is cut and the lower helical gear 164b is rotated, the direction of the nozzles 152a and 152b of the rotary plates 162 & 162b is changed in the vertical direction. The direction of the spiral groove of the upper worm gear 164a is opposite to the direction of the spiral groove of the lower worm gear leg. For example, the upper (four) wheel center becomes the right screw, and the lower side worm gear 164b becomes the left screw. Therefore, when the rotary shaft is rotated, the upper rotary plate 162a and the lower rotary plate (four) rotate in the opposite direction of 320012 24, and the ejection direction of the core 15 Torr of each nozzle 152 also changes in the opposite direction. When the number of slaves of the multi-stage rolling mill 1 that switches the number of switchable stages is set as shown in FIG. 9 and FIG. 1 , the number of the nozzles connected to the one end of the rotating shaft 65 is up to 166 ′ and the nozzles 152 a are adjusted. The spray direction of the 15 ties allows the rolling lubricant L to be surely attached to the work rolls 52, 53, or the work rolls 82, 83. Thus, the number of stages of the multi-stage rolling mill 1 that switches the number of switchable segments is such that the rolling lubricant L is reliably supplied to the work rolls, so that precise plate thickness control can be performed. The preferred embodiments of the present invention have been described above, but the present invention is not described. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit and scope of the invention.
