Definitions

  • the present invention relates to a water jet device surrounding a passageway along which, for instance, a bar to be heated is moved.
  • the passageway may comprise a pair of rails; but for a lengthy bar, the term passageway is to mean the space occupied by this bar.
  • a jet device surrounding a passage is not in itself bound to a specific use, but proves to be extremely useful, in particular, for the heating of crude bars which give off scale when heated to a high temperature by a heating coil. Short circuits may occur in the coil because of the falling scale and therefore may seriously perturbate the heating process.
  • the water screen formed by jets 6 from the nozzles or holes 5 by getting heavier inside the coil 7 takes out a major portion of the infrared radiation emitted by the heated articles running through the passage 2.
  • a jet device surrounding a passage way, wherein an article to be heated is moved comprising a ring extending around said passage way and a series of nozzles distributed along a base circle on the periphery of the ring for directing jets of water in the direction of their axes, the axis of each said nozzle being inclined by the same predetermined angle with respect to the plane of the base circle and being tangent to a neck circle spaced from said plane and perpendicular to the radius of the point of contact on the neck circle, said neck circle being coaxial with and narrower than said base circle and coaxial with and wider than said passage way and being located inside an induction heating coil.
