Definitions

  • .lt is also known to use a single stand reduction unit and when the product has been passed entirely through the mill and wound upon a spool or reel, it is stored and cooled while a previously rolled coil of strip is then once again introduced into the mill and once again rolled to acomplish further reduction.
  • a previously rolled coil of strip is then once again introduced into the mill and once again rolled to acomplish further reduction.
  • a further object of the invention is to provide a novel assemblable receptacle including a bottom and upstanding spaced side walls joined thereto with the terminal end portions of the opposite edges of each of the upstanding spaced walls being vertically disposed adjacent to the pairs of working rolls and adapted to conform thereto so as to cool the diametrically opposed peripheral faces of the rolls as well as the strip material passing therebetween.
  • a still further object of the invention is to provide a sectionalized receptacle, each complemental portion of which may be assembled between the working rolls by lateral introduction of each of the half portions thereof from opposite sides of the spaced stands of the mill whereupon they may be suitably fastened at their bottom portions in abutting relation.
  • Still another object of the invention is to provide valving means for controlling the quantity of coolant contained in the spaced receptacles.
  • FIG. 1 is a schematic side view partially in section and partially in elevation showing a series of rolling mill stands and the coolant system therefor;
  • FIG. 2 is a View on line 22 of FIG. '1.
  • the rolling stands comprise the usual upper and lower back-up rolls and the custom: ary work-engaging rolls. Also, as shown in this view, there is a reel :11 from which the strip material 12 is fed through the working mill rolls and at the exit end or beyond the last rolling mill stand there is positioned a take-up reel 13 adapted to store the rolled product.
  • suitable means are provided for driving the reels 11 and 13 and the work-engaging rolls so as .to maintain a suitable and constant tension on the roled product.
  • screw-downs are actuated to compress the rolls to achieve the reduction required for the first pass through the stands all of which is well-known in this art.
  • a series of paired spray means 14-18 are arranged to provide a convergent flow of fluid which, as shown, is directed toward the strip material and substantially at the nips of the work-engaging rolls as the material progresses through the respective passes of the stands.
  • the initial set or pair of convergent spray means i.e.
  • the longitudinally extending bottom wall 26 is interrupted by a semi-cylindrical portion 23, 24 which cooperates to provide a means defining an opening or perforation inthe bottom wall of the assembled receptacle within which a suitable valve means 25 may be positioned and adapted to control the level of liquid in .the receptacle.
  • a suitable valve means 25 may be positioned and adapted to control the level of liquid in .the receptacle.
  • Each side wall 27 has two opposed terminal edges 29 which are of arcuate configuration to conform to the perimeter of the vertically arranged upper and lower rolls in each of stands 10, 20 and 30.
  • those faces of the strip engaging rolls that are turned towards either of the receptacles 21 or 22 and are disposed between the two spaced imaginary horizontal planes containing the bottom wall 26, on the one hand, and the upper edge '28, on the other hand, are submerged in the liquid coolant. It follows that the strip 12 extending between two stands and engaged by the upper and lower rolls is also submerged in the coolant.
  • top edge portions of the receptacle of slightly unequal height with the lower edge being provided with any suitable outlet or overflow means so that the effluent which spills from the receptacle can be fed to a sump or refrigerating means and thence to a pump for return to the spray means.
  • the valve means 25 referred to hereinbefore may perform a plurality of functions, such a sthat of acting as a draining means for ther eceptacles, a means to till the receptacles when rolling is to be undertaken, and with the inclusion of suitable control means may compensate for the quantity of coolant which is normally introduced to the spray means so that only a limited amount of overflow is passed to the sump or refrigerating means.
  • a rolling mill of the type including at least two pairs of spaced and horizontally aligned strip engaging rolls, the rolls in each pair being vertically disposed and including an upper strip engaging roll and a lower strip engaging roll, cooling means for applying a liquid medium to cool said rolls and the strip engaged thereby during rolling, the improvement in said cooling means comprising,
  • a receptacle disposed between said pairs of rolls and adapted to contain liquid coolant, said receptacle having (1) a bottom wall disposed substantially horizontally in a plane below the axis of said lower strip engaging rolls,
  • each said side wall extending parallel to the rolling direction and having (a) substantially horizontally extending upper edge disposed in a horizontal plane above the axis of said upper strip engaging rolls,
  • (B) means introducing liquid coolant into said receptacle
  • An improved cooling means as claimed in claim 1, wherein said means introducing liquid coolant into the receptacle includes plural means positioned within and adjacent to the opposite ends of its longitudinal extremity for directing a coolant medium in convergent streams 0 toward the traveling strip and substantially at the nip of the work-engaging rolls.
  • adjustable draining means includes valve means positioned in one of said walls of said receptacle to control the level of the coolant medium therein.
  • valve means is automatically controlled from a remote station.
