Definitions

  • This invention relates to a liquid-diverting apparatus for use with a cooling system for hot workpieces, such as, strip, plate and the like and, more particularly, to such apparatus employed to divert quickly coolant delivered by a cooling system wherein it is not possible, at least practically, to instantaneously commence or discontinue the flow of the coolant onto the workpiece.
  • the present invention provides a diverting apparatus for selectively and quickly controlling the delivery of the coolant onto a workpiece, particularly when the coolant is delivered by a device that requires lost time in either being able to commence the flow or interrupt the flow of coolant onto a workpiece.
  • an apparatus to selectively and instantaneously divert liquid coolant discharged from a siphon coolant system or the like employed for cooling workpieces being conveyed thereunder comprising a coolant container arranged at a spaced superimposed distance from the workpieces to be cooled, said container having associated therewith a discrete input coolant means and a discrete output 3,299,900 Patented Jan. 24, 1967 I coolant means for discharging coolant from said conbearing block assemblies 12.
  • coolant-diverting means selectively positionable between the discharge portion of said container and the workpieces, power means connected to said diverting means for positioning said diverting means into and out of a coolant-diverting position, whereby the delivery of coolant onto said workpiece or its interruption in instantaneously controlled.
  • FIGURE 1 is an elevational view of a diverter employed in conjunction with a hot strip coolant device
  • FIGURE 2 is an elevational view' taken along lines IIII of FIGURE 1. 7
  • FIGURE 1 there is illustrated in FIGURE 1 one of the rollers 11 that makes up a hot runout table employed for conveying a hot metallic strip S.
  • the roller 11 is supported at each end by anti-friction These assemblies are mounted on a structural support 13 that is secured to the foundation in a usual manner.
  • the roller 11 is connected to an electrical rnotor 14 mounted at one side of the table.
  • Conventional strip side guards 15 and 16, shown in phantom, are arranged at the outer ends of the roller to prevent the strip from accidentally traveling off the roller.
  • a vertical support beam 17 is mounted on the foundation at the motor side of the roller 11. Pivotally connected by a pin 18 to the top of this beam is a fabricated water box 19 which includes a bottom plate 21. It will be appreciated in referring to FIGURE 2 that is a plurality of water boxes 19 are provided, being arranged in a sideby-side relationship along the roller table. Since the boxes are similarly constructed, reference will only be made to one of them.
  • the water box is provided with vertical baffle plates 22 and 23 which form a water reservoir 24 that extends the full length of the water box 19.
  • a water input pipe 20 (shown only in FIGURE 1) supplies water to this reservoir. Passing through each of the baflie plates 22 and 23 are a plurality of inverted U shaped pipes 25, 26, 27 and 28.
  • FIGURE 2 With particular reference now to FIGURE 2 and to the diverter apparatus, there are provided a plurality of elongated U shaped coolant-diverting pans 36 longitudinally arranged at the underside of the plates 21 for operative communication with the discharge ends of the U shaped pipes. These pans are enclosed at one end by end platen 36a and open at the other end so that coolant can pass from the diverter pan into a suitable drain, not shown in the drawings.
  • Each diverter is secured to an elongated shaft 37 which is rotatably received at each end by mounting blocks 38 and 39 that are secured to the plate 21.
  • a lever arm 41 is affixed to the outboard end of shaft 37 adjacent the block 38.
  • each diverter pan 36 is positioned so as to communicate with and receive coolant discharged from the pipes 27 and 28 of one water box and pipes 25 and 26 of the succeeding water box.
  • a piston cylinder assembly 29 shown only in FIGURE I, mounted on the support beam 17 and having its rod end connected to an arm 31 which is, in turn, connected to the plate 21.
  • a counterbalance 32 also is secured to the plate 21 to balance the overhung weight of the water box assembly.
  • a combination stop and leveling adjustment is provided to assure that each water box is level and the water level will not vary along the length of each box.
  • This level adjustment consists of a threaded bolt 33 received in a plate 34 which is connected to an upright beam 35 secured to the foundation. Operation of the piston cylinder 29 will pivot the water box 19 about the pin 18 to a position where it will not obstruct access to the roller which'is shown in FIGURE 1 by dot and dash lines.
  • the above-described water discharge device is initially placed in operation preparatory to actual strip cooling. This is accomplished, as heretofore mentioned, by raising the water level in the reservoir 24 slightly above the U shaped bend in the siphon pipes. When this occurs, a siphon action is established in the pipes which discharge the water from the reservoir through the bottom plate 21. As the water emerges from the delivery end of each pipe, it will either fall into the diverter pans or into the strip. Should the water pass directly into the diverter pans 36, it will be collected and directed to the motor side of the roller table and pass into a suitable drain, which may be connected to the coolant water supply tank, not shown in the drawings.
  • the present invention also provides a quickly responsive strip coolant control such as may be employed during the acceleration of the strip where the number of cooling devices is quickly and sequentially increased for maintaining uniform strip temperature.
  • the number of coolant devices employed may be quickly increased by exerting the desired control over the operation of the piston cylinder assemblies 42, to position the diverting pans 36 into the desired position
  • the pres ent invention not only provides a quickly responsive coolant control, but also a dependable and predictable control.
  • An apparatus for controlling the application of coolant onto a passing workpiece by diverting its direction of flow comprising:
  • coolant discharge means positioned at a spaced distance from the workpiece for delivering coolant onto the workpiece
  • coolant supply means for deliverying coolant to said discharge means
  • a U shaped coolant diverter pan selectively positionable intermediate said discharge means and the workpiece and adjacent to said discharge means for diverting coolant delivered from said discharge means so as not to allow the coolant to contact the workpiece
  • said coolant diverter pan having its open side arranged to receive coolant from said discharge means and having one of its ends closed so as not to allow coolant to escape from the closed end thereof, and
  • said coolant discharge means includes,
  • said reservoirs containing a plurality of U shaped coolant delivery pipes, each having coolant receiving ends positioned in said reservoirs and coolant discharge ends for delivering coolant from said reservoir onto a workpiece,
  • said coolant diverter pan being pivotally secured to said coolant discharge means and arranged to communicate with the discharge ends of said delivery pipes, and
  • said power means including a piston cylinder assembly operatively connected to said diverter pan.
