Description

The invention relates to a deflection device for deflecting a melt stream, for example in a sub-molding combination during block casting. The invention further relates to a base molding with such a deflection device. In addition, the invention relates to a pressing tool and a method for producing such a deflection device.

A common metallurgical casting process for producing geometrically simple bodies, which are primarily intended for non-cutting further processing, for example in forges or rolling mills, is block casting. In block casting, molten steel is poured into a permanent mold, the so-called mold, and solidifies in it to form a ingot. The mold is usually filled with the molten steel from below. For this purpose, the molten steel is fed to a corresponding filling system which, when the mold is filled from below, is usually also referred to as a base molding. The filling system comprises, for example, a vertical tube provided with a filling funnel and a horizontal tube connected to the flow, which opens into a lower region of the mold. The vertical tube is usually of such a length that the mold is filled with the molten steel melt solely by the hydrostatic pressure generated in the vertical tube.

In order to connect the vertical pipe with the horizontal pipe in terms of flow, the filling system has a deflection device. The deflection device can also have a distribution function if several molds are to be filled with the molten steel. The deflection device is then fluidly connected to a plurality of horizontal tubes which each open into one of the molds. Such a deflection device is usually also referred to as a distributor or Königstein.

From the EP 2 965 838 A1 a Königstein is known, which in addition to a flow chamber also has an impact chamber. The flow chamber has an inlet opening on an upper base surface, through which liquid molten steel coming from the vertical tube flows into the flow chamber. The flow chamber has an access opening to the impact chamber on a lower base area and therefore distributes a plurality of outlet openings through which the molten steel flows into the associated horizontal tubes. The access opening to the baffle chamber and the inlet opening to the flow chamber are both in the center of the Königstein, so that the molten steel flows from the inlet opening directly into the baffle chamber, fills the baffle chamber, overflows into the overlying flow chamber, over there through the outlet openings the associated horizontal pipes distributed and flows into the associated molds.

It is an object of the invention to provide at least one deflection device of the type mentioned at the outset, which is an alternative or further development to the known deflection device.

The object is achieved with a deflection device which has the features of claim 1. The object is further achieved with a deflection device which has the features of claim 14. To achieve the object, a base molding combination with the features of claim 18, a pressing tool with the features of claim 19 and a method with the features of claim 20 are also proposed. Advantageous embodiments and / or refinements and / or aspects of the invention result from the subclaims, the following description and the figures.

A basic deflection device for deflecting a melt stream, for example in a sub-casting combination, preferably in block casting, comprises a base body which, for example, has or consists of a refractory material. The base body in turn comprises a flow chamber, in particular for passing the melt stream, an entrance to the flow chamber and at least one exit from the flow chamber. In particular, the entrance is set up to be fluidly connected to a pipe block of a filling pipe and / or pouring funnel. In particular, the at least one outlet is set up to be fluidly connected to a channel block.

In particular, it is provided that the flow chamber has a bottom surface, an inlet opening opposite the bottom surface and at least one outlet opening. For example, the inlet opening is delimited by a peripheral edge, in particular, and is fluidly connected to the inlet via an inlet channel. For example, the at least one outlet opening is fluidly connected to the at least one outlet via an outlet channel.

In particular, it is further provided that the base body comprises an impact chamber for the melt flow, which is fluidly connected to the flow chamber via an access opening, in particular a single access opening. For example, the impact chamber has an interior and a wall surface surrounding the interior, at least one surface section of which can be used as an impact surface for the melt stream, the interior being accessible for the melt stream via the access opening. For example, the impact chamber is closed except for one access opening. It has been shown that a lowering of the flow rate of the melt stream in the deflection device or in the flow chamber is favored by the impact chamber. This counteracts any thermomechanical corrosion phenomena which are favored by a high flow rate of the melt stream, such as occurs, for example, in the pouring phase of a casting process.

In one embodiment it is provided that the access opening faces the inlet opening. The access opening of the baffle chamber therefore faces the inlet opening of the flow chamber. It is now particularly provided that the access opening has an opening area which is arranged transversely, in particular orthogonally or essentially orthogonally, to a central axis of the inlet channel in the region of the inlet opening. It is furthermore particularly provided that at least a section of the particularly peripheral edge of the inlet opening lies within the access opening.

As a result, a measure is taken to counteract the fact that during a casting process the pouring jet emerging from the inlet opening strikes the outer edge of the access opening to the impact chamber. It has been shown that such impingement of the pouring jet on the outer edge of the access opening promotes abrasive wear by removing material particles from the wall. The material particles are then found in the melt as impurities and reduce their quality. It could be observed that such signs of wear are counteracted if at least one section of the edge of the inlet opening lies within the access opening. It could also be observed that with regard to any abrasive signs of wear, it is advantageous if the edge of the inlet opening lies completely within the opening of the impact chamber.

In a further embodiment it is provided that the inlet channel has a cross section which tapers towards the inlet opening of the flow chamber. In particular, it is provided that the inlet channel in the area of the entrance and in the area of the inlet opening have cross-sectional areas of different sizes, the cross-sectional area in the area of the entrance being larger than the cross-sectional area in the area of the inlet opening. As a result, on the one hand the inlet opening can be designed in the manner described above and on the other hand the dimensions of the entrance of the base body or the deflection device can remain unchanged, for example in order to connect a conventional funnel tube to it.

In order to achieve the tapering of the inlet duct, it can be provided that the inlet duct is conical and / or inclined over a length section. In addition or as an alternative, the inlet channel can be curved, for example convex or concave, over a length section or over the one length section.

The shape of the cross-sectional area of the inlet channel in the area of the inlet opening can be corresponding or different from the shape of the cross-sectional area of the inlet channel in the area of the entrance. For example, the inlet opening has a round, in particular circular, cross section. For example, the entrance has a round, in particular circular, cross section. In principle, it is also possible for the entrance and / or the inlet opening to have an angular, in particular polygonal, cross-sectional shape. It is also possible that the entrance has a round cross-sectional shape and the inlet opening has a square cross-sectional shape, or conversely the inlet channel has a square cross-sectional shape and the inlet opening has a round cross-sectional shape.

According to a further embodiment, it is provided that the outlet channel has a cross section which widens towards the at least one outlet. In particular, it is provided that the outlet channel in the area of the outlet opening and in the area of the outlet have different cross-sectional areas, the cross-sectional area in the area of the outlet being larger than the cross-sectional area in the area of the outlet opening. This measure aims to reduce the speed of the melt flow in the outlet channel. This counteracts any thermomechanical corrosion in the outlet duct. Such corrosion phenomena can occur, for example, if the outlet channel has a non-rectilinear course.

In order to achieve the expansion of the outlet channel, it can be provided that the outlet channel is conical and / or inclined over a length section. In addition or as an alternative, the outlet channel can be curved, for example convex or concave, over a length section or over the one length section.

It can be the shape of the cross-sectional area of the outlet channel in the area of the outlet opening in relation to the shape of the cross-sectional area of the outlet channel in the region of the outlet may be corresponding or different. For example, the outlet opening has a round, in particular circular, cross section. For example, the exit has a round, in particular circular, cross section. In principle, it is also possible for the outlet opening and / or the outlet to have an angular, in particular polygonal, cross-sectional shape. It is also possible for the outlet opening to have a round cross-sectional shape and for the outlet to have an angular cross-sectional shape or, conversely, for the outlet opening to have a square cross-sectional shape and for the outlet to have a round cross-sectional shape.

A further embodiment consists in the outlet channel having at least two channel sections. In particular, it is provided that one of the channel sections runs axially or essentially axially with respect to a central axis of the access opening. In particular, it is further provided that another of the channel sections runs radially or essentially radially with respect to the central axis of the access opening. For example, the axially extending channel section is assigned the at least one outlet opening and the radially running channel section the at least one outlet. As a result, the melt flow is deflected via the outlet channel. In this case, the melt flow can be deflected through the outlet channel in a direction which already corresponds to the desired deflection by means of the deflection device or through which at least part of the desired deflection has been carried out.

In particular, it is provided that the at least one outlet opening and / or the access opening are assigned to the bottom surface of the flow chamber, in particular in a plane formed by the bottom surface. This favors a technically simple production. In this case, for example, it is provided that the outlet channel associated with the at least one outlet opening has at least two channel sections which are designed as described above. As a result, in the installed state of the deflection device in a base molding combination, a pouring stream of the molten steel flows from the inlet opening of the flow chamber into the baffle chamber during a casting process, the baffle chamber fills, pours through overflow into the flow chamber, flows there via the at least one outlet opening into the Exhaust duct flows in which the steel melt undergoes a deflection due to the at least two duct sections and flows into an associated mold via the outlet of the deflection device and an at least one duct block connected to it.

Simple manufacture is also favored if, according to one embodiment, the baffle chamber is at least partially formed by a depression in the bottom surface of the flow chamber. For example, the depression is formed by a material recess. The impact chamber can have a cylindrical shape and can have, for example, a round, in particular circular, or angular, in particular square or other polygonal cross section.

In one possible embodiment, the inlet opening of the flow chamber and the access opening of the impact chamber are arranged coaxially with respect to a common central axis. In particular, it is provided that the inlet channel is arranged coaxially with respect to the common central axis. In particular, it is further provided that the interior of the impact chamber has a central axis which coincides with the common central axis. It has been shown that such a structure favors low-wear pouring. Such a structure also favors cost advantages in the manufacture of the deflection device.

In order to counteract the abrasive wear described above, which is favored by the kinetic energy of the pouring jet, it is provided in this embodiment in particular that the inlet opening of the flow chamber and the access opening of the impact chamber each have a diameter with respect to the common central axis, the diameter of the inlet opening being smaller than the diameter of the access opening. It has been observed that abrasive wear and tear is counteracted effectively if the diameter of the inlet opening is at least 5 percent, preferably at least 10 percent smaller than the diameter of the access opening of the impact chamber. The percentage refers to the diameter of the access opening, which is assumed to be 100 percent.

Furthermore, the inlet channel should have a diameter in the region of the entrance which is larger than the diameter of the inlet opening. For example, the diameter of the inlet is at least 5 percent, preferably at least 10 percent larger than the diameter of the inlet opening. The percentage refers to the diameter of the inlet opening, which is assumed to be 100 percent. The tapering of the inlet channel described above is thereby realized.

In order to lower the flow rate of the melt stream in the at least one outlet channel, it is in this embodiment in particular provided that the at least outlet opening has a diameter which is smaller than the diameter of the outlet. It has been observed that a favorable flow rate is achieved if the diameter of the at least one outlet opening is at least 10 percent, preferably at least 20 percent smaller than the diameter of the outlet. The percentage refers to the diameter of the outlet, which is assumed to be 100 percent.

It has also been shown that the diameter of the entrance should correspond to the diameter of the access opening or should substantially correspond to or be larger than the diameter of the access opening. It was observed that a measure was taken to achieve favorable flow conditions for the melt flow in the deflection device.

In this direction, the measure also aims that, according to one embodiment, the baffle chamber has a depth which is bounded at the top by the access opening and at the bottom by a bottom, and the flow chamber has a depth which is bounded at the top by the inlet opening and to is bounded at the bottom by the bottom surface, the depth of the impact chamber being approximately 2.0 times to approximately 2.5 times, preferably approximately 2.3 times as large as the depth of the flow chamber.

A further embodiment consists in that the base body is at least in two parts and comprises an upper part and a lower part, which together form the flow chamber. This favors a technically simple manufacture of the interior of the flow chamber, since the interior is only formed by assembling the upper part with the lower part and before that the walls of the upper part and / or the lower part forming the interior are exposed and thus for processing in a simple manner can be reached.

For example, the upper part and the lower part are designed to expose the bottom surface of the flow chamber by lifting the upper part from the lower part, so that the opening of the baffle chamber and the at least one outlet opening of the flow chamber is or is accessible. In this respect, it makes sense that the outlet opening of the flow chamber and the access opening of the baffle chamber are assigned to the bottom surface of the flow chamber, in particular are present in the bottom surface of the flow chamber.

For example, the inlet opening is assigned to the upper part, in particular the upper part has the inlet opening. For example, the upper part is assigned the entrance and / or the inlet duct, in particular the upper part has the entrance and / or the inlet duct. For example, the lower part is assigned the at least one outlet opening, in particular the lower part has the at least one outlet opening. For example, the impact chamber is assigned to the lower part, in particular the lower part has the impact chamber. For example, the lower part is also assigned the at least one outlet channel and / or the at least one outlet, in particular the lower part has the at least one outlet channel and / or the at least one outlet. It also makes sense that the lower part has a mounting surface in order to be able to place or set up the base body or the deflection device in a defined manner on a surface or the like reference object via the mounting surface.

It makes sense that the upper part and the lower part are connected to one another via a plug connection, one of the two parts having or forming an insertion receptacle and the other part having an insertion section inserted therein. The production of a leakage-free or at least leakage-free connection of the upper part and the lower part is favored with one another. For this purpose, it is provided, for example, that the plug-in connection forms a parting line which, based on the longitudinal section of the base body, has a Z-shaped contour or essentially a Z-shaped contour. The longitudinal section of the base body is to be understood in particular as a cut surface which is parallel to the central axis of the cut base body.

According to a further embodiment, it is provided that the flow chamber comprises a plurality of outlet openings, which are arranged distributed around the impact chamber, and in each case one of the outlet openings is fluidly connected to an associated outlet via an associated outlet channel. As a result, the deflection device also has a distribution function. A melt stream flowing into the distribution device via the inlet is divided via the several outlet openings in the flow chamber into a corresponding number of partial streams, which can be used for the simultaneous filling of several molds. A uniform division of the melt flow into the several partial flows is advantageous if, according to one embodiment, the baffle chamber is arranged in the center of the base body and in particular the outlet openings are distributed around the baffle chamber, that is to say their central axes are arranged concentrically to the center of the base body.

A further aspect of the invention relates to a base molding combination which comprises at least one of the embodiments and / or configurations of the deflection device described above, comprises at least one pipe stone of a casting funnel and at least one channel stone. The pipe block can be flow-connected to the input of the deflection device and the channel block to the at least one outlet of the deflection device.

In a further aspect of the invention, a pressing tool is provided for producing at least one of the embodiments and / or refinements of the deflection device described above. The pressing tool comprises a pressing die, which has a base section and at least two projections projecting from the base section. In particular, it is provided that the projections are configured with respect to one another and / or with regard to their dimensions and / or with regard to their shape such that the impact chamber and the at least one outlet channel are produced by the projections when the press ram is inserted into a blank for the Lower part of the deflection device is pressed.

For example, the projections are cylindrical in cross section, in particular the projections form sleeves and / or hollow cylinders. The hollow structure of the projections makes it possible for material of the blank that has been displaced during the pressing process to be discharged to the outside via the inner cavity of the projections, in particular to be automatically pushed out through the cavity by the forces generated during the pressing process.
