  • Publication number: 20050028962
    Abstract: A device for cooling and guiding a beam blank in a curved secondary cooling zone of a beam blank caster includes an intrados web support roller with a cylindrical bearing surface that is interrupted by grooves. The grooves are designed so as to avoid an over-flow generating cooling water dam up behind the intrados web support roller by channeling sufficient cooling water underneath the intrados web support roller axially through the intrados channel of the beam blank. The cooling water overflow produces a quench of the intrados tips of the flanges, which results in transverse cracks of these tips during straightening of the beam blank.

  • Patent number: 5303901
    Abstract: A blowing lance for refining metals by blowing a gas onto a surface of a metal bath is presented. This lance has an adjustable tuyere for generating a supersonic refining gas flow and a blowing head with a set of fixed tuyeres opening into a front dome of the blowing head and dividing the supersonic gas flow into individual free jets. A cyclic modulator modulates a flow rate through the set of fixed tuyeres so that the flow rate in a first subset of tuyeres does not vary synchronously with the flow rate in a second subset of tuyeres, i.e., the flow rates in both subsets of tuyeres increase or decrease at the same time and they do not reach their minimum value or their maximum value at the same moment.

  • Patent number: 5227118
    Abstract: The present invention relates to a refining lance. It relates more particularly to a lance of the kind used for supplying from above, onto a metal bath, the oxidizing gas required for refining the molten metal contained in a metallurgical vessel. It includes a rotating device to divide the refining gas flow into an even number of separate gas jets that are more or less identical. The gas jets exit the head of the lance in angles which are substantially equal with respect to the longitudinal axis of the lance but in diametrically opposite directions with respect to the said axis.

  • Patent number: 4993691
    Abstract: A gas injection lance for use in metal refining is disclosed. The lance includes a tube having an inner diameter profile and a throttle member slidably received with the tube. The tube and throttle member define an annular gas flowpath. The throttle body may be moved axially within the tube to modify the characteristics of the flowpath.

  • Patent number: 4971297
    Abstract: Nozzles for a refining lance are presented which are spaced upwardly from the head of the lance and supply post-combustion oxygen to the space above a molten metal bath undergoing refining. Each of the nozzles has a mouthpiece with two parallel sharp edges which are arranged in planes passing substantially through the axis of the lance and which are connected by slightly rounded edges. Above the mouthpiece of each nozzle is a converging part.
