  • Patent number: 10393438
    Abstract: At least one row of fixed copper coolers are arranged in a furnace in a cantilevered horizontal shelf inside and fastened to an external steel ring support and the steel containment shell. These shelves redirect and take all the weight of refractory brick and floating cooling blocks that are stacked on above. Each fixed copper cooler in the shelves cantilever shoulder-to-shoulder over any refractory brick and floating cooling blocks that may be stacked beneath to relieve that lower portion of the wall from the weight of the upper wall. When relieved of such weight, the risks of sudden catastrophic failure of the lower walls is reduced. These bricks in the lower walls can also be allowed to wear and thin beyond what would be reasonable in a conventional design without any cantilevered shelving.

  • Patent number: 8961864
    Abstract: Exemplary embodiments of the invention include a method and apparatus for cooling a metal strip that is being advanced in a generally horizontal fashion. The method involves delivering a coolant liquid onto a lower surface of the strip from below across the entire width of the strip, preventing the coolant liquid from contacting the upper surface of the strip, and optionally subsequently removing the coolant liquid from the lower surface. The coolant liquid is prevented from contacting the upper surface by forming a gas-directing channel immediately above the upper surface of the strip adjacent to one or preferably both lateral edges of the strip and forcing a gas through the channel in a direction generally away from a center of the strip towards the one or both lateral edges to deflect coolant liquid away from the upper surface of the strip. The apparatus provides means for carrying out these steps.

  • Patent number: 7718018
    Abstract: A method of cooling both surfaces of steel plate, which stably secures precision of cooling control from a start of cooling to an end so as to uniformly cool the top and bottom surfaces of the steel plate and thereby stably secures the steel plate quality and cools the steel plate down to a target temperature with a good precision. The method comprises dividing a steel plate cooling region into at least a spray impact part region and a spray non-impact part region, predicting a heat transfer coefficient for each divided region in advance, computing a predicted temperature history of the steel plate based on this predicted value, and setting and controlling amounts of sprayed coolant on the spray impact part regions by top and bottom surface nozzles.

  • Publication number: 20090315231
    Abstract: In a forming mold equipped with a cooling channel for circulation of a refrigerant composed of a cooling gas and a atomized cooling liquid, any increase of back pressure attributed to evaporation of the refrigerant fed to the cooling channel is inhibited to thereby attain cooling acceleration, and further any occurrence of rust or scale by the refrigerant circulated through the cooling channel is prevented. Accordingly, a channel for supply of the refrigerant to the cooling channel of the forming mold is provided with air pressure source for trapping of air in the supply channel and pressure feeding of the same; oxygen separation means for separation removal of oxygen from the pressure fed air to thereby lower the oxygen concentration of the air; and atomizing means for spraying of the cooling liquid into the air with oxygen concentration lowered.
