Definitions

  • This invention relates to a roller pressure high intensity quench system for quench reducing the temperature of metal plate to provideit with selected properties. More particularly, this invention pertains to an apparatus in which directly opposed tired rollers engage plate at a temperature above the critical transformation temperature and in which the metal plate moves along a predetermined path and is initially impinged angularly with a curtain of quench fluid on the top and bottom surfaces.
  • the present invention is designed to be used in connection with the invention disclosed in our application Ser. No. 370,554.
  • the present invention produces a high intensity continuous quench system.
  • a high velocity curtain of water or other suitable quench fluid strikes the Work at an angle. This prevents the quenching fluid from reaching a part of the metal plate which has not advanced to the point where the high velocity curtain of quench fluid strikes the plate.
  • the angle also assists in forcing the quench fluid down the line through a plurality of staggered tired rolls used to restrain the metal plate while it is subjected to a severe quench.
  • a subsequent spray pipe discharges quench fluid uniformity covering the area between two tired restraining rolls on both the top and bottom of the plate. The fluid also impinges the plate proximately where the plate leaves the tired rolls whereby any d-ry spots caused by an interruption of the flow of quenching fluid along the plate surface are substantially eliminated.
  • each curved deflector is positioned so that its free end is directed toward the other deflector and toward the exit end of the apparatus allowing space between the free end of each deflector to permit the metal plate to pass freely through, means supplying a quenching fluid under pressure to each spray pipe, the fluid leaves the holes and strikes the deflector which causes a high velocity curtain of liquid to impinge on the metal plate at an angle preventing any splash back in the opposite direction from which the metal plate is entering the apparatus, the fluid is directed along the metal plate toward the exit end of the apparatus.
  • the curved deflector is positioned and shaped so that the quench curtain strikes the metal plate at an angle between 10 and 40 and impinges on the metal plate at a minimum distance from the means supporting and restraining so as to maximize the distance from the point of quench impingement to the first restraining tired rolls.
  • FIGURE 1 is a longitudinal sectional view of the quench apparatus
  • FIGURE 2 is an isometric portion of the quench apparatus including the first and second spray pipes with the plate travelling within the restraining support rolls.
  • the apparatus comprises a plurality of upper and lower entry cylindrical rolls 10, 12, 14 and 16.
  • a pair of high intensity spray pipes 18 and 20 are mounted between rolls 12 and 46 and between rolls 16 and 44 respectively.
  • Each of the spray pipes 18 and 20 have a plurality of holes 26 and 28 longitudinally aligned and radially offset from the vertical axis of each spr-ay pipe toward the entry end 30 of the apparatus.
  • Each of the spray pipes 18 and 20 have curved deflector plates 32 and 34 which are attached adjacent the aligned holes 26 and 28 respectively. The curved deflectors 32 and 34 extend from the spray pipes 18 and 20 toward the entry end 30 of the apparatus and curve toward the opposite spray pipes 20 and 18.
  • each curved deflector plate 32 and 34 is positioned so that its free end is directed toward the other deflector 34 and 32 and toward the exit end 36 of the apparatus allowing space between the free end of each deflector 32 and 34 to permit the metal plate 38 to pass freely between.
  • Spray pipes 18 and 20 are parallel and vertically alinged.
  • the holes 26 and 28 are positioned so that they face the other spray pipes 20 and 18 respectively.
  • the holes 26 and 28 and deflectors 32 and 34 are positioned such that quenching fluid leaves holes 26 and 28 and strikes the deflectors 32 and 34 respectively. This results in a high veleocity quench curtain which impinges the work 38 at angles 40 and 42 having a range between 10 and 40.
  • the holes 26 and 28 and deflectors 32 and 34 are positioned so that the quench curtain impinges on the work 38 at a minimum distance from the entry rolls 12 and 16 and with a maximum distance between the point of impingement and the tired rolls 46 and 44.
  • the purpose of this is to delay the first interruption of the quench fluid by the tires 48 and 50 and still maintain the required plate restraint for flatness.
  • the quench fluid striking the deflectors 32 and 34 provides curtains of fluid which angul-arly impinge the work and prevents the quench fluid from reaching a part of the work 38 which has not advanced to the quench curtain impingement.
  • the tired rolls 46 and 44 have a plurality of tires 48 and 50 respectively. The space between the tires permits quenching fluid to escape in the direction of the exit 36.
  • the tired rolls 46 and 44 are followed by a subsequent pair of tired rolls 52 and 54 which have tires 56 and 58 respectively.
  • a third set of tired rolls 60 and 62 follow tired rolls 52 and 54 and then the work 38 enters the lower intensity quench system disclosed in our patent application Ser. No. 370,554 referred to generally as 64. All of the tires on the rolls are staggered with respect to the preceding and succeeding rolls. All of the lower tires 50 and 8 are directly beneath in alignment with the upper tires 48 and 56.
  • a second and third pair of spray pipes 66, 68, 70 and 72 are placed within the spaces between tired rolls 46, 52, 44, 54, 60 and 62.
  • the spray pipes have a plurality of holes 74, 76, 78 and 80 which are positioned so that patterns 82, 84, 86 and 88 are produced which uniformly directs jets of quench fluid toward the plate surface between restraining rolls 46, 44, 52, 54, 60 and 62.
  • Spray pipes 18 and 20 are supplied quench fluid through a range of pressure up to 160 psi. at headers 90 and 92 respectively and spray pipes 66, 68, 70 and 72 are supplied by headers 94 and 96. All of the cylindrical rolls and the tired rolls 10, 14, 12, 16, 44, 46, 52, 54, 60 and 62 are driven at the same speed by means of a sprocket and chain motor drive shown in our earlier patent application Ser. No. 370,554.
  • rollers 12, 18, 46, 52 and 60 rotate in the opposite direction as the rolls 14, 16, 44, 54 and 62. This is accomplished by the chain drive mechanism shown in FIGURE 4 in'our patent application Ser. No. 370,554. All of the rollers are journalled and supported by bearings as shown in our patent application Ser. No. 370,554.
  • the upper rollers have a load 98 exerting a downward force which is transmitted to the work 3-8.
  • Beams 100 support rolls 46, 44, 52, 54, 60 and 62.
  • the upper frame 102 supports the support beams 100 and all of the upper rolls 10, 12, 46, 52 and 60 and spray pipes 18, 66 and 70.
  • the frame 102 is prepositioned until the top cylindrical rolls are positioned to restrain the work 38.
  • the work 38 then leaves a furnace and engages an entry zone of the apparatus comprising restraining rolls 10, 12, 14 and 16.
  • the work 38 passes between restraining support rolls 12, 16, 46, 44, 52, 54, 60 and 62.
  • the quench fluid strikes deflectors 32 and 34 and then impinges the work 38 at point 104 at high velocity which sets the cooling temperature of the work.
  • the quench fluid travels between the staggered tires 48, 50, 56 and 58 and follows the work which is restrained and supported by the tired rolls 46, 44, 52, 54, 60 and 62.
  • the quench fluid from spray pipes 66, 68, 70 and 72 flow in patterns 82, 84, 86 and 88 maintaining the coo-led temperature reached at the impingement point 104.
  • the work then travels into a low intensity quench system 64 disclosed in our application Ser. No. 370,554.
