Definitions
- the present invention relates to an impact pad for continuous casting, foreseen to be located on the floor of a refractory tundish which receives from a ladle the molten metal which has to pass from the aforementioned tundish to the pertinent mould, such that the impact pad constitutes the a species of box with an opening on the top for the entry of the molten metal which is poured from the ladle, all of this in order to achieve an adequate orientation of the flow of molten metal, and also to avoid turbulence and splashing which normally give rise to a series of problems and drawbacks when said turbulence and splashing impact against the flow that is poured into the box that constitutes the pad.
- the object of the invention is to provide a new type of impact pad for continuous casting which as well as having the form of a box has its floor wavy or grooved in order to achieve results better than those obtained by means of the known impact plates or boxes.
- the molten metal which is poured into the forming moulds comes from a refractory tundish which is situated between the pertinent ladle supplier of the molten metal and the forming mould itself.
- a refractory tundish which is situated between the pertinent ladle supplier of the molten metal and the forming mould itself.
- the floor of the damping platform is completely flat, which prevents an adequate orientation of the flow of molten metal which is poured thereupon, and also leads to a notable erosion in the floor of the box that constitutes the platform, precisely as a consequence of the flatness of the floor.
- the damping impact platform has the form of a box, but with its floor flat, with the aforementioned inconveniences and problems, in the North American Patent, though having a wavy platform, this constitutes a flat piece independent of the tundish, as well as not being duly designed in its placement with the aim of achieving optimum results in the pouring and orientation of the flow.
- the impact pad for continuous casting which is proposed, being foreseen for collocating on the floor of a conventional refractory tundish, presents the particularity of combining in a single unit the boxlike configuration and the corresponding wavy floor, that on one hand eliminates the problems and inconveniences found in the damping impact boxes for continuous casting having a flat floor, and on the other hand, those found with wavy plates but which are independent and flat elements that are not boxlike.
- the impact pad object of the invention is constituted by a boxlike body with any appropriate configuration, be this rectangular, trapezoidal, triangular and even circular, wherein the width of the floor has to be greater than the width of the mouth, and the latter also to be provided with a step with respect to the internal side surface, for the purpose of determining a means for reorienting the flow toward the exit, avoiding turbulence and other problems.
- the box-shaped body has its floor wavy, wherein the wave can have the length the same as or different to its amplitude, or else the wave can be in form of a "V", or the floor can even be grooved, in such a manner that in whatever case, regardless of the configuration of the pad, and the disposition or form of the undulations, the benefits that are obtained with respect to the traditional systems, including those of the two European patents and the North American patent mentioned in the previous section, can be summarised as follows:
- the impact pad for continuous casting of the invention is made up of a boxlike body (1), the mouth (2) of which is of notably less in width than the actual base or floor of the body (1) or box which constitutes the impact pad itself.
- said impact pad (1) is quadrangular in outline, the internal surface of its side wall (3) being upwardly convergent, until a step (4) is reached which determines not only a smaller width of the mouth (2) with respect to the floor of the box or pad (1), but also an obtuse dihedron which shall determine the flow of molten metal which is poured into the box that constitutes this impact pad (1), before reaching the exit and in its displacement over the side and internal surface (3), instead of exiting directly through the mouth (2) it impacts against this step (4) avoiding any type of turbulence in the outward direction.
- the pad (1) mentioned has its floor (5) wavy, which orients the flow of molten metal poured from the ladle toward the interior of said boxlike impact pad (1).
- the pad (1') is circular in shape and the undulations (5') concentric, having in this case the internal side surface (3') of its side wall straight, in which the step (4') forms a right angle with that internal side surface (3') of the wall of the boxlike pad (1).
- the mouth (2') of the pad (1') is in this case circular, as illustrated in figure 3.
- the pad (1'') is triangular in outline, with the pertinent mouth (2'') having the same shape, the internal side surface (3'') is straight, determining that the step (4'') forms a right angle with that internal side surface (3'').
- grooves (5'') have been implemented in the floor, which are also wavy in profile, with the same function and purpose as those provided for the forms of embodiment illustrated in the figures 1-2 and 3-4, or else with many other configurations that could be mentioned, since as has been stated throughout the present description, the impact pad has to present as particular characteristic that of forming a species of closed box with it mouth of less width than the floor, and being able to adopt whatever geometry, be this rectangular, trapezoidal, triangular and even circular, and its floor wavy or grooved.
