Definitions

  • ABSTRACT An apparatus for cooling a coating on a wire comprising three separate coaxial passages through which the wire is adapted to pass after coating, the first and second passages passing through the walls of a pressurized gas manifold, the third passage having a tangentially directed liquid inlet bore therein and being flared at its lower end to define a liquid outlet passage I between its lower end and the upper end of said second passage, means supplying liquid to said bore at such a rate as to cause a steady helical flow of liquid which fills said third passage but flows primarily from said outlet passage, and means supplying gas to said manifold at a pressure sufficient to cause substantially all of said quenching liquid to flow through said outlet passage.
  • the coating In the galvanizing of wires or strips, it is necessary for the coating to be quenched and it is desirable that this quenching be effected as soon as possible after the coating process is completed. It is also necessary that there should be no mechanical abrasion of the coating before it has been quenched to a hardness sufficient to prevent its deformation or "pick up by the guides necessary for directional control through the coating and quenching apparatus. Another requirement of a quench is that it be designed so that a minimal amount of quench water is allowed to pass into the coating apparatus.
  • the invention provides an apparatus for cooling'a coating ona wire, strip or other continuous length of material (hereinafter termed wire"), comprising a passage through which the wire is adapted to be passed after it has been coated, said passage being constructed to provide a space surrounding said wire, a laterally directed quenching liquid inlet bore opening into said passage and adapted to substantially fill said space with quenching liquid, said passage being constructed to divert the quenching liquid away from said wire at the wire entry end of said passage.
  • wire a passage through which the wire is adapted to be passed after it has been coated, said passage being constructed to provide a space surrounding said wire, a laterally directed quenching liquid inlet bore opening into said passage and adapted to substantially fill said space with quenching liquid, said passage being constructed to divert the quenching liquid away from said wire at the wire entry end of said passage.
  • theinvention provides a method of cooling a coating on a wire, strip or other continuous length of material (hereinafter termed wire) comprising passing said wire through a passage, directing a 1 quenching liquid into said passage to substantially fill the space between the wire and passage and diverting the quenching liquid away from said wire at the wire entry end of said passage.
  • FIG. 1 is an end elevation of a water quench embodyin g the invention showing its position in a wire galvanizns P t;
  • FIG. 3 is a fragmentary sectional end elevation taken along line 3-3 of FIG. 2.
  • the water quench apparatus Q embodying the invention comprises a plurality of quenching units (see FIG. 3.) each including three coaxial tubes 1, 2 and 3 through which the wire, coated with zinc by an ap'- paratus A located adjacent the water quench as shown in FIG. 1, is passed for the quenching operation, the direction of wire travel being upwardly through the tubes 1, 2 and 3 respectively.
  • the apparatus A is preferably of the type described in copending application Ser. No. 805,145 filed Mar. 7, 1969.
  • the tube 3 is formed with a primary water inlet bore 4 and a secondary water inlet bore 4a smaller than bore 4, both of which open tangentially into the tube3 (see FIG.
  • the water inlet bores 4, 4a are located suitably between the ends of the tube 3 so that during operation substantially the whole of the annular space between the wire and tube 3 is substantially filled with water.
  • the tube 3 is flared at its lower end 3a and the upper end of tube 2 is located adjacent the flared portion to define an annular passage 5 through which the bulk of the water in tube 3 passes into a water overflow reservoir 6.
  • the motion of the water in tube 3, the flared end 3a of the tube, bore sizes and water flow rate are selected to ensure that water supplied through bores 4 and 4a is substantially balanced with outflow through passage 5.
  • tubes 2 and 1 open into a pressurized air manifold 8 having an air inlet 9 and at least one small drain port 10 for each unit which opens into the reservoir 6.
  • the air in manifold 8 flows principally through tubes 1 and 2, a small amount being lost through port 10.
  • the flow of air through tube 2 assists in the deflection of water through passage 5 and the air flow through tube 1 assists in preventing escape of water from tube 1 into the coating apparatus A.
  • tube 2 is outwardly flared as shown so that any water passing through this tube against the air flow will tend to be diverted from entering the tube 1 and will pass through drain hole 10 to the reservoir 6.
  • the air inlet 9, tubes 1 and 2 and the rate of air flow are selected to provide satisfactory operation in use.
  • an apertured baffle plate B is positioned between the tube 1 and the coating baths to deflect most of the air which escapes from tube 1 and to a great extent prevent extinguishing the flame at coating ap- It will be evident from the above that the quenching apparatus according to the embodiment may be safely used adjacent to the coating apparatus so as to quench the coated wire immediately after the coating process with a minimum of water escaping from the quench to the coating baths.
  • tube 3 For strips, it may be necessary to replace tube 3 by a rectangular section tube. For other sections suitably shaped tubes may be required.
  • the described embodiment has been designed for a high speed galvanizing plant.
  • only one water inlet bore need be provided in tube 3 but it preferably has a nozzle which projects into the tube 3 so as to be adjacent the wire.
  • the upper end of tube 2 be located within the flared end of tube 3.
  • the apparatus of the invention may be adapted for purposes other than cooling so the terms cooling and quenching should be construed to include other operations capable of being performed by the apparatus, for example heating or chemical treatments of wires", coated or otherwise.
  • Apparatus for cooling a continuous length of material comprising an upright conduit through which the material passes with clearance, means for moving the material upwardly through the conduit, the conduit having a laterally directed quenching liquid inlet bore opening into the interior of the conduit, means to introduce quenching liquid through the bore into the conduit, and means for directing a flow of gas upward against the lower end of the conduit to divert the liquid away from the material at the lower end of the conduit.
  • Apparatus as claimed m claim 1 there being a plurality of said conduits arranged parallel in a bank to receive a plurality of lengths of material, all of said conduits having in common the same said means for supplying liquid.
