Definitions
- the present invention relates to a taphole device for casting molten metallic or non-metallic materials, which device has a variable opening as defined in the preamble of claim 1.
- 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, p. ex. a plug or a plate, between the orifice and the material to be poured.
- an object p. ex. a plug or a plate
- these systems only work well in the open or closed position.
- the jets are highly dispersed, which greatly hinders the quality of the casting.
- Patent FR-A-1 478 920 describes a pouring device for liquid metal comprising a rotary valve having a convex cylindrical surface which can slide along a partially cylindrical recess.
- the object of the present invention is to provide a taphole device, comprising two cylinders with parallel axes provided with grooves, allowing the starting, the precise adjustment of the flow rate and the stopping of the pouring of liquid metals and non-metallic materials. in fusion, ensuring at all times identical geometric conditions at the outlet of the tap hole.
- the device according to the invention which is characterized in that it comprises means making it possible to seal the cylinders relative to one another as well as means of fixing and sealing relative to the container containing the liquid material.
- 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.
- a drive means which may 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 p. ex. be clamping screws. Additional means are provided for sealing the two cylinders with respect to each other, which means may consist of, for example: ex. in a shaping according to 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 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.
- FIG. 1 there are shown two cylinders A and B which each have a groove 10 in pseudo-elliptical shape. Due to the variation of the profile of these grooves along the circumference of each cylinder, a rotation of these p. ex. in the direction of the arrows, leads to a variation of the opening circumscribed by the profile of the superimposed grooves.
- FIG. 1A will result in a maximum opening 01 as the depth of the grooves is the greatest at the location of the contact line between the cylinders A and B.
- To arrive at a more restricted opening it suffices to turn cylinders A and B counter-clockwise, cylinder A being turned anticlockwise; this will result in the opening 02 of FIG. 1B.
- Figure 2 shows essentially the same cylinders as those shown in Figure 1, with however another embodiment of the groove. This has a simple profile to obtain, since the bottom is straight, as shown in Figures 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 p. ex. that shown in FIG. 2B results in an opening of elliptical or oval profile.
- Figure 2C shows the closed position of the tap hole. Note that the arrows that appear in Figures 1A, B, C, and 2A, B, C indicate 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.
- 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.
- 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 -engine.
- the pressure means 4 which can be p. ex. clamping screws.
- the cylinders can be executed either in metal, which will be the case during the casting of molten non-metallic 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 steelmaking ladle , under the hearth of an electric steel or foundry furnace, under the basket-distributor of a continuous casting, or even on the discharge part of a converter.
- metal which will be the case during the casting of molten non-metallic materials, such as sand, slag, rocks etc.
- a refractory material when the device is applied in the casting of liquid metals, and when it is mounted under a steelmaking ladle , under the hearth of an electric steel or foundry furnace, under the basket-distributor of a continuous casting, or even on the discharge part of a converter.
- the metal cylinders In the case of the casting of non-metallic materials, it is useful to provide the metal cylinders with a water cooling system, by providing channels 6 intended to convey the cooling water.
