  • Apparatus and method for continuously casting steel slabs
    Patent number: 5247988
    Abstract: In a continuous casting mold for casting slabs of metal, the mold is cooled by sprays of coolant directed against the outside of the mold. The mold (11) is divided into four zones (zones 1, 2, 3 and 4) and the rates of heat extraction in the different zones are varied so as to obtain a substantially uniform rate of cooling and solidification of the metal being cast, thereby reducing or eliminating the incidence of face cracking in the cast slab.

  • Apparatus and method for cleaning the outside of the mold tube in a continuous casting machine
    Patent number: 5190593
    Abstract: An apparatus and method for cleaning the precipitate from the outside of a mold tube in a metal casting machine, includes spray nozzles positioned around the mold tube for spraying a chemical solution against the tube, in situ, to dissolve precipitate thereon, thus avoiding the necessity of removing the mold tube from the machine or otherwise shutting down the casting operation. In spray cooled machines, the water used to cool the mold tube can be used to rinse away the solution and dissolved precipitate.

  • System for oscillating mold tube in continuous casting apparatus
    Patent number: 4669525
    Abstract: A mold tube supported in but spaced from a mold housing is vibrated by at least one vibrator connected to the mold tube through a keeper plate.

  • Spray cooling system for continuous steel casting machine
    Patent number: 4494594
    Abstract: A mold tube is contained within an open water-cooling vessel, and the tube is cooled by directing water sprays at it. Although a steam barrier would otherwise form around the mold tube and prevent water penetration, thus resulting in a tube melt-down, this effect of the steam barrier is eliminated if certain operating parameters have values within critical ranges. The important parameters include the distance between the spray nozzles and the mold tube, the angle of each water spray, and the overlap of the sprays on the mold tube.

  • System for oscillating mold tube in continuous steel casting machine
    Patent number: 4483385
    Abstract: A mold tube is contained within an open water-cooling vessel, and the tube is cooled by directing water sprays at it. Because of the use of a water-cooling system which does not require a pressure-tight integral mold tube/water system, the cooling system may remain stationary while the mold tube is oscillated. In this way the oscillating mechanism can be relatively inexpensive, the total weight which must be moved up and down typically being in the range of 80-200 pounds.
