Definitions

  • This invention relates to a turn-over cooling bank for metal stock.
  • metal stock particularly that having a square or rectangular cross section
  • it is hot rolled or continuously cast and then cut to length.
  • the stock is then allowed to cool on a cooling bank during which time it is displaced intermittently along the length of the bank. It is also desirable to rotate the stock as it moves along the bank so that it cools more uniformly and thereby avoids distortion of the stock.
  • the carrier rack which is provided with a horizontal travel which is adjustable between predetermined limits.
  • the bank is to accommodate stock of differing cross-sectional dimensions, then it is necessary to be able to adjust the amount of forward travel of the stock as it is moved by the carrier rack and deposited on to the pick-up rack. This is to make sure that the stock is deposited on the correct part of the notched support surface of the pick-up rack so that the stock turns over through the correct angle without excessive sticking and bumping which would damage the stock and the support surface of the racks.
  • a turn-over cooling bank for metal stock generally of square cross-section and say 100-160 mm length of side, includes a plurality of carrier racks 1, of which one is shown in.the figures. These racks are of elongate form with a notched upper support surface 3. The racks are arranged in parallel, side-by-side, spaced apart relation and each rack has a number of downwardly extending brackets 5 spaced apart along its length. The corresponding brackets of all the carrier racks are connected to transverse beams 25. As shown in Figure 7, the transverse beams 25 are connected together by underslung tie beams 24.
  • a plurality of pick-up racks 7, of which one is shown in the figures, are arranged in parallel, side-by-side, spaced apart relation and are interdigitated with the carrier racks 1. These racks have a notched upper support surface 9 and each rack has a number of downwardly. extending brackets 11 spaced apart along its length and the corresponding brackets of these racks are connected by transverse beams 27. The beams 27 are connected together by underslung tie beams 26.
  • the beams 25, 27 are arranged in pairs in side-by-side relation and beneath each beam there is a roller track 25A, 27A respectively.
  • Each pair of beams is supported on a rocker unit 29, consisting of a fixed pedestal 31 having a pair of rocker plates 33 pivotally mounted thereon, and connected together by two pins each carrying a roller 35.
  • One roller engages the underside of the track 27A beneath the beam 27 and the other roller engages the underside of the track 25A beneath the beam 25.
  • a mechanism to be described in more detail later, is employed to rock the plates 33 relative to the fixed pedestal 31 to reciprocate the rollers 35 in a vertical direction with the rollers being out of phase, that is, as one roller is raised, the other is lowered.
  • the movement of the rollers causes the carrier racks to be reciprocated up and down 180 0 out of phase with the up and down movement of the pick-up racks.
  • a drive means which includes a rotatable shaft 15, mounted substantially horizontally in fixed bearings 17.
  • An eccentric 41 is mounted on the shaft 15 and a lift arm 39 is mounted on the eccentric.
  • the lift arm is connected by respective links 37 to pivots on the plates 33. As the shaft is rotated, the eccentric causes the links 37 to reciprocate substantially horizontally and to pivot the rocker plates 33 with respect to the pedestals 31.
  • the pick-up racks 7 are thus subjected to both vertical and horizontal reciprocatory movement simultaneously and, consequently, the actual movement of the racks 7 is along an elliptical path.
  • the stroke, both the vertical and the horizontal movements applied to the pick-up racks, is fixed and, consequently, the shape of the elliptical path is fixed.
  • the eccentric members 43, 45 are adjusted to cause the stock, lowered by the carrier racks on to the pick-up racks, to engage the required part of the notches on the pick-up racks for the stock to be turned, without excessive sliding. If stock of different cross-sectional dimensions is to be cooled on the bank, then the eccentrics have to be adjusted ⁇ to ensure that the stock is placed on the pick-up racks at such as position and at such an entry angle that the stock is turned without excessive sliding.
  • the two eccentric members 43, 45 can be adjusted between positions which give different amounts of offset and also between positions which give the same amount of offset but different entry angles for the stock as it is placed on the pick-up racks. This facility enables the best entry angle to be chosen to ensure that the stock rotates through the required angle each time it is placed on the pick-up racks, even though the stock has differing cross-sectional dimensions.
  • the pitch of the notches on the pick-up racks and the carrier racks, and both the vertical and horizontal displacement of the racks, are all dependent on the range of products to be transported along the cooling bank.
  • the pitch of the notches on the racks is roughly fixed as being equal to the distance across the diagonals of the maximum stock to be transported plus approximately 50 mm to maintain this as a maximum gap so as not to restrict air flow for cooling purposes.
  • the fixing of the vertical and horizontal movements required is rather more difficult bnut basically consists of adding the notch height of the pick-up rack to the notch height of the carrier rack and then adding 20 mm for additional clearance. Having fixed the vertical height of each ellipse in this way and the relative distance between the two racks, the ideal width of the ellipse for the maximum size stock can be established, as can the ideal width for the minimum size stock.
  • carrier racks have been described as having the adjustable horizontal stroke, they could be provided with a fixed horizontal stroke and the pick-up racks could be provided with an adjustable horizontal stroke. As a further option, both sets of racks could be provided with an adjustable horizontal stroke.
