Definitions

  • This invention relates to an apparatus for continuously quenching a heated metal plate moving and restrained in a plane.
  • this invention pertains to apparatus in which a pair of slotted quench headers direct quench fluid at an angle in the direction of movement of the plate which is subsequently restrained by a pair of spiraled grooved rollers engaging the plate on the top and bottom surfaces.
  • This invention represents an improvement over the structure shown in my U.S. Pat. No. 3,420,083 (issued Jan. 7, 1969). That patent discloses the use of grooved rolls whereas my present invention teaches replacing those grooved rolls with spiral grooved rolls having sloped walls forming the grooves. These rolls are used to restrain the plate during the quenching operation.
  • my U.S. Pat. No. 3,420,083 large quantities of water are delivered to the plate surface at a high velocity. At the point of initial impingement, the angle must be such as to assure the prevention of any water being driven back along the plate surface in a direction opposite to that of the plate advance.
  • the plate In present practices to avoid surface tempering, the plate is moved at a relatively slow speed to allow time to elapse before the point of water interruption. This results in plate warping between the points of restraint before and after impingement of the quench fluid and cooling of the plate to such a degree that the warpage is fixed.
  • Spiral grooved rolls permits higher plate speeds through the quench with a considerable improvement in plate flatness. Actual maximum speeds were originally 30 to 40 feet per minute for the thinnest plate. The speed was then increased to 60 feet per minute with the use of annular grooves. When using spiral grooved rolls, the speed is no longer limited by the occurrence of surface tempering caused by the interruption of flow of quench fluid along the plate. Therefore, plate 3/16 inch thick can be passed through the quench at speeds over 250 feet per minute.
  • New techniques in quenching use the heat remaining in the plate after rolling. Such an operation requires higher plate speeds through the quench.
  • the one problem is that heavy plate takes less time to roll and more time to quench.
  • the solution is to quench at higher plate speed which is made possible by the spiral grooved roll.
  • the invention of the new header makes it possible to release the water at a point about 2 inches from the point of impingement. No deflector is required to change individual jets to a curtain because the fluid is in the form of a curtain at the point of release.
  • No deflector is required to change individual jets to a curtain because the fluid is in the form of a curtain at the point of release.
  • a nearrow band of impingement fluid with a high perpendicular velocity component with only about 40 p.s.i. water pressure at the point of release.
  • I provide an apparatus for continuously quenching a heated metal plate moving and restrained in a plane, the improvement comprising means applying a curtain of quench fluid which impinges the top and bottom surfaces of the metal plate; the fluid is applied in the direction of movement of the metal plate; and a pair of spiral grooved rollers positioned and spaced apart to engage the top and bottom surfaces of the metal plate, the rollers are positioned subsequent to the impingement of the quench fluid in the direction of movement of the metal plate.
  • I preferably provide that the spiral grooved rollers are formed by sloped walls and the spiral going from the center to each end of the roll.
  • the means applying a curtain of quench fluid comprises a pair of corresponding headers positioned above and below the travel of the metal plate, each header formed by a gate member converging with a rigid back member to form a longitudinal slit across the path of the plate travel, the slit oriented to face the plate at an angle in the same direction of travel of the metal plate, the gate member is adjustable to vary the opening of the slit and means supplying quench fluid to each header.
  • FIG. 1 is a longitudinal sectional view of the quench apparatus
  • FIG. 2 is an isometric portion of the quench apparatus including the quench headers 18 and 20 with a pair of spiraled grooved rolls and a subsequent pair of quench spray pipes showing a plate traveling between the pairs of headers and rolls;
  • FIG. 3 is an elevational view of a spiraled grooved roll
  • FIG. 4 is a cross sectional view of the roll shown in Flg. 3 and taken on the line IV-IV of FIG. 3;
  • FIG. 5 is an enlarged fragmentary view of one of the quench headers
  • FIG. 6 is an elevational view of another embodiment of a spiraled grooved roll which can be used instead of the spiral grooved roll shown in FIG. 3;
  • FIG. 7 is another embodiment of an enlarged fragmentary view of a quench header which can be used instead of the header shown in FIGS. 2 and 5;
  • FIG. 8 is an elevational view of another embodiment of the threaded rod and nut at the gate of the header shown in FIG. 7.
  • the apparatus comprises a plurality of upper and lower entry cylindrical rolls 10, 12, 14 and 16 which restrain the plate 30 in a plane at the entry end 26 of the apparatus.
  • Adjacent to rolls 12 and 16 are top and bottom quench headers 18 and 20 which produce high velocity quench curtains (sheets of liquid) 62 and 64 respectively which impinge the metal plate 30 on top and bottom surfaces of the plate.
  • Positioned beyond quench headers 18 and 20 in point of travel of the plate 30 are spiraled grooved rolls 22 and 24 engaging the top and bottom of the plate 30 followed by quench spray pipes 32 and 34 which supply quench fluid on the plate 30 and toward rolls 22, 24, 36 and 38.
  • Positioned beyond quench spray pipes 32 and 34 are additional spiraled grooved rolls 36 and 38 which engage the top and bottom of the plate 30.
  • Positioned beyond those rolls are quench spray pipes 40 and 42 and additional spiraled grooved rolls 44 and 46.
  • the main headers 48, 50, 52 and 54 supply quench headers 18 and 20 and quench spray pipes 32, 34, 40 and 42 with quench fluid.
  • the quench spray popes 32, 34, 40 and 42 have a plurality of openings (or nozzles) to release the quench fluid.

  • the upper rolls have a load 56 exerting a downward force which is transmitted to the plate 30. All of the cylindrical rolls and the grooved rolls 10, 12, 14, 16, 22, 24, 36, 38, 44 and 46 are driven at the same speed by means of a sprocket and chain motor drive shown in my earlier U.S. Pat. No. 3,423,254. Rolls 10, 12, 22, 36 and 44 rotate in the opposite direction from rolls 14, 16, 24, 38 and 46. Each of the rolls are journaled and supported by bearings as shown in my U.S. Pat. No. 3,423,254.
  • the upper frame 60 is pre-positioned until the top cylindrical rolls 10 are positioned to restrain the metal plate 30 as it enters the apparatus after leaving a furnace. The metal plate 30 then passes between rolls 12, 16, 22, 24, 36, 38, 44 and 46.
  • Quench fluid 62 and 64 in the form of a continuous high velocity curtain impinges the metal plate 30 which sets the cooling temperature of the metal plate 30.
  • the high velocity quench curtains impinge ythe plate 30 on top and bottom surfaces at an angle between 10 and 40 which prevents the quench fluid from reaching a part of the work 30 which has not advanced to the point of impingement.
  • FIG. 2 shows a more detailed isometric view of the headers 18 and 20 which provide the initial quench curtains 62 and 64 with the use of the spiraled grooved rolls 22, 24, 36 and 38 with additional quenching spray pipes 32 and 34. All of the spiraled grooved rolls 22, 24, 36, 38, 44 and 46 are identical. Rolls 44 and 46 are not shown in FIG. 2.
  • the spiraled grooved roll 22 (also shown in FIGS. 3 and 4) shows a plurality of spiraled rib-like walls 74 disposed in parallel spaced relation, the walls extending from the center 76 in opposite directions outwardly to each end 78 and 80 (shown also in FIG. 3).
  • the spiraled walls are tapered symmetrically in thickness, that is the side surfaces 82 and 84 slope inwardly as the wall approaches the outer surface of the roll 22 (shown in FIG. 4).
  • Quench fluid is also deflected toward the plate areas downstream in the line of travel of the plate to the points of interruption thereby bringing quench liquid quickly into those areas where the flow of quench fluid was interrupted by the intermittent contact of the spirally grooved roll.
  • the sloped sides of the walls provide an additional component of quench fluid directed toward the plate surface.
  • FIGS. 2 and 5 show detailed isometric views of the headers 18 and 20.
  • the header 18 is coupled to the main header 48 by the conduit coupling 86 shown in FIG. 5.
  • Headers 18 and 20 are identical except they are reversed in position and are positioned directly above and below and facing each other allowing the plate to pass between them.
  • Header 18 has a gate member 88 which converges with a rigid back member 90 to form a longitudinal slit 92 across the path of the plate 30 travel.
  • the slit 92 is oriented to face the plate 30 at an angle in the same direction of the travel of the metal plate 30.
  • Gate member 88 is adjustable to vary the opening of the longitudinal slit 92 by loosening bolts 94 and 96 which are inserted through oversized holes.
  • the gate member 88 can be moved upwardly or downwardly to vary the slit opening 92.
  • a hinge member 98 couples the gate member 88 and can be swung open after bolt 94 is removed for ease of cleaning obstructions from the slot and replacemnt of gate member 88.
  • quench spray pipes 32, 34, 40 and 42 provide quench fluid on the plate 30 toward each of the spiraled grooved rolls that the particular quench spray pipe straddles.
  • the initial quench fluid in the form of quench curtains 62 and 64 impinge the metal plate 30 at a high velocity which sets the cooling temperature of the plate 30.
  • the quench fluid then travels between the spiraled grooved rolls 22, 24, 36, 38, 44 and 46 and follows the metal plate 30 which is restrained by the rolls.
  • the additional quench fluid from quench spray pipes 32, 34, 40 and 42 maintains the cool temperature reached at the initial impingement point 100 (FIG. 2) on the plate 30 surface.
  • the spiral grooved rolls 22, 24 shown in FIGS. 2 and 3 are expensive to make and machine.
  • the spiral grooved roll generally shown as 102 in FIG. 6 was developed.
  • lt comprises a shaft 104 on which are mounted a plurality of discrete cylindrical spiral segments 106 and 108.
  • the segments 106 have their spiral grooves oriented in reverse direction of the cylindrical spiral groove segments 108.
  • the segments are divided in their orientation at the center 110 of the shaft 104.
  • the use of the segments gives the advantage of being able to use segments which can be cut on machines for cutting worms or they can be cut on a suitable gear cutting machine. By using segments made from gear cutting machines the cost of producing the spiral groove rolls is greatly reduced.

  • the other end of the gate member 116 opposite the pivot 118 converges with the U-shaped rigid back member 114 to form a longitudinal slit 122 across the path of the plate travel.
  • the slit is oriented to face the plate at an angle in the same direction of travel of the metal plate.
  • a rod 124 extends through both the gate member 116 and U-shaped rigid back member 114. It is threaded at each end and has corresponding nuts 126 and 128. Rubber gaskets 130 and 132 hold leakage through gate and the rigid U- shaped back member to a minimum.
  • nut 128 is rotated. This enables one to flush out any accumlated obstructions.
  • the reducers would all be in a line and would have their inward shafts all coupled together in series. In this manner all the adjusting nuts could be turned simultaneously and uniformly by rotating the coupled input shafts either manually or by a suitable powered unit.
