Definitions

  • the present invention relates to a taphole device intended essentially for the pouring of liquid metals, which device has a variable opening, for the purpose of starting, stopping and regulating the flow of metal during casting.
  • the tap hole devices known in the metallurgical industry essentially comprise the conventional stopper systems with a stopper or a drawer.
  • the principle of these systems is that we enlarge resp. narrows the section of an orifice, removing resp. by gradually bringing an object p. ex. a plug or plate, between the orifice and the metal to be poured.
  • the geometry of the casting jet is necessarily affected by the changes in the geometry of the orifice which occur according to this principle, these systems only work well in the open or closed position. For intermediate openings the jets are highly dispersed which hampers the quality of the casting. It is therefore useful to provide more efficient tap hole devices.
  • the applicant proposed a tap hole device allowing the start, the precise adjustment of the flow rate and the stopping of the flow of materials non-metallic molten, ensuring at all times identical geometric conditions at the outlet of the tap hole.
  • This device which is in principle also applicable to the casting of liquid metals, provides that two cylinders with parallel axes and movable around their respective axes, have a common contact line. At least one of the cylinders has a groove which extends over a portion of the circumference of the cylinder. This groove is oriented perpendicular to the axis and has a profile and in particular a depth which varies so as to pass through a maximum.
  • the advantage of the device described mainly lies in the fact that it makes it possible to continuously vary the opening of the taphole and to make precise adjustments to the poured flow rate.
  • an opening of any geometric shape can be obtained.
  • pseudo-elliptical grooves give a perfectly circular opening.
  • the axis of the orifice does not move.
  • the object of the present invention is to produce a device operating according to the known principle, and in which the mechanical elements which come directly into contact with the liquid metal are made of refractory materials possibly covered with a refractory layer of high resistance against abrasion and are arranged in relation to each other so that any existing geometric irregularity resp. created during the operation of the installation is automatically compensated in order to preserve the seal at all times.
  • the main advantage of the device according to the invention lies in the fact that one is no longer forced or. to require strict, and therefore expensive, geometric tolerances, or to use cylinders with identical geometric dimensions.
  • the disassembly and reassembly of the entire device is rapid.
  • the assembly being housed in a sealed box, the invention makes it possible to avoid any contact of the liquid metal with the air until the outlet of the tap hole.
  • Fig. 1 shows a schematic top view of the tap hole device according to the invention
  • fig. 3 an exploded view of certain pieces of refractory material.
  • a shell 11 preferably made of ceramic fibers, on the majority of the faces of the housing 5 opposite the cylinders.
  • This shell which has low compressibility, is also capable of compensating for variations in the diameter of the cylinders.
  • a plate of refractory material 23 placed in the bottom of the housing 5.
  • the plate 23 and the bottom of the housing 5 have two holes through which pass two axes for the rotation of the cylinders.
  • the ends of the axes have a shape which fills a recess 21 of rectangular cross section in the cylinders 1, 2.
  • the synchronous rotation of the cylinders, in opposite directions with respect to each other is ensured by means of two toothed wheels 24
  • the wheels can be driven by a lever, a jack or a servo motor.
  • the cylinders to which it is relatively easy to give a substantially identical height, have one of the bases which is supported on the plate 23.
  • a layer of refractory fibers 31 provides thermal insulation between the refractory plate 23 and the rear plate of the housing 32.
  • cams actuated by levers can also be used for this purpose.
  • connecting rods actuated by a hydraulic or electric actuator instead of using screw thread cartridges to adjust the force applied to the cylinders by the pads 6, cams actuated by levers can also be used for this purpose.
