Title: Improvements in the continuous cooling of metal slabs and the like in a bath of liquid
IPC: B21B45/02
Filed: 1964-01-27
Abstract: <PICT:1044563/C6-C7/1> A method and apparatus for the continuous cooling of slabs, flats and thick plates of metal in a water bath is characterized by the feature that the said items to be cooled are immersed in the water in a vertical or substantially vertical position. The apparatus comprises means for guiding the slabs to the water bath in a horizontal position, a delivery appliance for placing the slabs vertically in the water bath 1, comprising a plurality of arms 10 which are rockable about a horizontal axis and, when in a vertical position slidably displacable in a vertical direction, means for moving the slab along the bath, and a removal appliance similar in construction to the delivery appliance.  The plurality of arms 10, each bent at the end to form a hook 11, are placed upon slides 12 which are rockable about a pivot 13.  The slab 7, to be placed in the water bath is slid in a horizontal position on to the arms 10, whilst the said arms are in the horizontal position, the weight of the slab causing the arms 10 and the slides 12 to pivot about the pivot 13 into the vertical position, and the arms 10 to then slide vertically downwards relative to the slides 12, the slab being supported within the hook 11 of the arms.  The slab is thus deposited in the water bath upon rollers 6 positioned near the bottom thereof, which slab is then moved the length of the bath, upon the rollers 6, by means of a pusher mechanism 9, to the withdrawal mechanism 5.  The arms 10 of the delivery appliance 3 are raised relative to the slides 12, and then returned with the slides to the horizontal position, ready for the next slab.  A braking mechanism, and means for withdrawing the device from the water bath, is provided by connecting the arms 10 with a traction drum fitted with a breaking device, by way of a traction rope 16 passing over a deflection pulley 17.  A power piston and cylinder 18 is connected to the slide 12 to prevent the arms 10 moving relative to the slides 12, except when in the vertical position. Scale is removed from the bottom of the water bath by means of downwardly directed water injecting nozzles 21, positioned below the rollers 6 and connected to high pressure water pipes 23.  The cooling water enters the bath by the inlet apertures 19 adjacent the removal appliance and leaves the bath via outlet apertures 20 adjacent the delivery appliance.  The bath may take the form of a narrow trough.
