Definitions

  • the present invention relates to a tap hole device intended essentially for pouring liquid materials, in particular molten metallic or non-metallic materials, which device has a variable opening, in order to start, stop and adjust the material flow 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 consists in that one enlarges resp. narrows the section of an orifice, removing resp. by gradually bringing an object, eg a plug or a plate, between the orifice and the material to be poured.
  • an object eg a plug or a plate
  • these systems only work well in the open or closed position.
  • the jets are highly dispersed which greatly hampers the quality of the casting. It is therefore useful to provide more efficient tap hole devices.
  • the object of the present invention is therefore to propose a taphole device allowing the start, the precise adjustment of the flow rate and the stopping of the pouring of molten material, by ensuring at all times identical geometric conditions at the outlet of the tap hole.
  • the device must be applicable to the casting of liquid metals and molten non-metallic materials.
  • the device according to the invention which is characterized in that two cylinders (A, B) with parallel axes and movable around their respective axes, have a common contact line and that at least one of the cylinders have a groove, while the other cylinder can be smooth.
  • the groove extends over a portion of the circumference of the cylinder, i.e. that it is oriented perpendicular to the axis and it has a profile and in particular a depth which varies so as to pass through a maximum.
  • the groove may have, according to a preferred embodiment, a pseudo-elliptical profile; one can nevertheless also provide simpler execution profiles, which however goes at the expense of the continuity of the geometry of the jet during the variation of the degree of opening of the taphole, as will be explained below.
  • the device according to the invention comprises means making it possible to drive the two cylinders synchronously, in order to position them so as to obtain the desired degree of opening of the tap hole.
  • means making it possible to drive the two cylinders synchronously, in order to position them so as to obtain the desired degree of opening of the tap hole.
  • the two cylinders with a pinion system and to provide a drive means which can be a simple lever or, in the case of more sophisticated applications, a servo-motor, acting on the one of the two cylinders.
  • means are provided for pressing the two cylinders against one another along their contact line. These means can, for example, be clamping screws. Additional means are also provided for sealing the two cylinders with respect to each other, which means may consist, for example, of a shaping in which one of the cylinders is nested in the other.
  • the main advantage of the device according to the invention obviously lies in the fact that it makes it possible to continuously vary the opening of the tap hole 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.
  • FIG. 1 shows a perspective view of two cylinders each provided with a pseudo-elliptical groove
  • fig. lA, 1B, 1C and 1D showing longitudinal and transverse sections of the same cylinders in different positions
  • fig. 2 shows a perspective view of two cylinders where the grooves have a straight bottom
  • fig. 2A, 2B and 2C showing longitudinal and transverse sections of these cylinders in different positions and the configurations of the openings resulting from these positions
  • FIG. 3 schematically shows a longitudinal section and a cross section of a possible embodiment of the device according to the invention.
  • FIG. 1 shows two cylinders (A and B) which each have a groove (10) in pseudo-elliptical shape. Due to the variation in the profile of these grooves along the circumference of each cylinder, a rotation thereof, eg in the direction of the arrows, leads to a variation of the opening circumscribed by the profile of the superimposed grooves.
  • the position shown in fig. lA will result in maximum opening (01) as the depth of the grooves is greatest at the location of the contact line between the cylinders (A and B).
  • the cylinder (A) being turned counter-clockwise; this will result in the opening (02) of FIG. 1B.
  • Fig. 2 essentially represents the same cylinders as those. shown in fig. 1, with however another embodiment of the groove. This has a simple profile to obtain, since the bottom is straight, as shown in Figs. 2A, 2B and 2C. However, it is easy to see in fig. 2A that in this precise case only the position where the bottoms of the grooves are parallel to each other, there is an opening in the form of a circle, while any other position, such as that shown, in fig. 2B results in an elliptical or oval profile opening.
  • Fig. 2C shows the closed position of the tap hole. Note that the arrows that appear in Figs. 1A, B, C and 2A, B, C indicating the direction of flow of the material to be poured.
  • FIG. 3 there is shown schematically a possible embodiment of the device according to the invention.
  • the cylinders (A, B) each provided with a groove (10) in the form of a pseudo-ellipse, generating in their position as shown, a circular opening (0).
  • the fixing means (1 and 2) of the block (3) which acts as a bearing for the two cylinders.
  • the displacement in synchronous rotation of the two cylinders, in opposite direction with respect to each other, is ensured by the pinions (5).
  • the rotation device which is not shown, can be a lever, a jack, or a servo motor.
  • the pressure means (4) which can be eg clamping screws.
  • the cylinders can be executed either in metal, which will be the case during the casting of non-metallic molten materials, such as sand, slag, rocks, etc. ., in the context of the manufacture of glass, mineral wool or ceramic fibers, either in a refractory material when the device is applied in the casting of liquid metals, and when it is mounted under a casting ladle steelworks, under the hearth of an electric steelmaking or foundry furnace, under the basket-distributor of a continuous casting, or even on the discharge part of a converter.
