Definitions
- the present invention relates to a method and a device for lateral flow guidance in strip casting by the Coanda effect.
- EP 0 635 323 B1 discloses a nozzle for continuous casting plants. In this case, a pouring tip for a nozzle of a continuous casting apparatus will be described. From US 4,526,223 a continuous casting with two cooling drums is known. From EP 0 859 675 a method and apparatus for casting a metal strip is known. WO 2008/087002 A1 discloses a method and a device for casting non-ferrous metal melts, in particular copper or copper alloys. When tape casting according to the Belt Casting technology, the hot, liquid melt from the distributor (tundish) must be placed on the moving sub-belt.
- the problem here is the combination of the uniform, horizontal distribution of the melt over the entire casting width, which can be up to two meters, and the simultaneous realization of high casting speeds of up to 30 m / min.
- special pouring or homogenizing devices are used, which are also referred to as snouts.
- the casting spouts can be closed (closed snout) or open (open snout).
- open spout the hot melt is in direct contact with the surrounding gas (air, inert gas).
- the melt coming from the distributor forms an open channel flow, which can be either subcritical (Froude number ⁇ 1) or supercritical (Froude number> 1).
- the Froude number for open channels is defined as
- Fr ; u is the flow velocity of the channel, g is the ground agitator
- the melt leaves the refractory material and forms a melting case with a certain drop height, which depends on the position of the pouring spout over the moving strip.
- the melt cools and is transported away.
- the initially still liquid melt on the conveyor belt is extremely sensitive from a fluid and heat engineering point of view. Long-lasting flow patterns are retained during solidification and produce an undesirable microstructure, both microscopically and macroscopically.
- the melt laterally constricted as a result of the interfacial tension during the overflow from the pouring spout onto the lower strip forms a hot strand, which generates undesired turbulences when impinging on the conveyor belt or also ensures that the lateral area on the lower belt is not even charged or filled with melt ,
- the constriction of the melt also occurs when the pouring spout is completely filled with melt until it exits.
- the strand induces turbulence and turbulence extending to the narrow but critical side region of the melt pool.
- the melt flow may already be released on the pouring spout.
- the melt constricts and thickens. This forms a hot strand.
- the hot strand emerges from the spout and strikes the underlying moving sub-band with high kinetic energy. On the tape it comes to intense, unwanted vortexes.
- the lateral flow generally has a higher momentum and higher kinetic energy than the mid-band flow. The melt therefore penetrates laterally with high momentum onto the conveyor belt, whereby the typical strands structure is retained and a non-uniform velocity profile is induced.
- Strip casting plants which operate according to the above-described method, require an inductive stirrer for homogenizing the melt.
- the object of the present invention is to provide a method and a device for lateral flow guidance of a molten metal during strip casting, whereby the stranding of the melt in the overflow reduced or completely suppressed by the casting spout on the moving belt and the associated undesirable microstructure in the band.
- the object of the present invention is achieved by a method for lateral, supporting flow guidance of a molten metal during strip casting, wherein
- the melt is guided via the distribution device, in particular casting spout (1), onto a moving belt.
- the present invention also relates to a method for the lateral, passive flow guidance of a molten metal during strip casting by utilizing the Coanda effect.
- the lateral, directed into the melt interior constriction of an open melt jet in the distribution to a moving conveyor belt (strip casting technology) is inventively reduced.
- the solidifying melt is distributed more uniformly over the casting width on the conveyor belt.
- the characteristic undesirable flow patterns at the strip edges are prevented.
- the melt is passed over a casting spout, in which the last stretch of the refractory side wall is specially curved three-dimensionally (convex, concave), in the form of a wing-like, hereinafter referred to as Coanda profile.
- the Coanda effect describes the property of a fluid jet or jet (gaseous, liquid) to attach to and follow a nearby convex wall. In this way, the fluid jet changes its original direction of propagation.
- the effect of the Coanda effect is based on the superposition of several physical mechanisms, essentially the Bemoulli effect, the molecular ones Forces between wall and fluid jet, the flow boundary layer and the pressure gradient in the flow direction.
- the contour of the Coanda profile already begins in or on the spout and is specially shaped beyond the spout and at the same time also in the direction of the treadmill. It is a three-dimensional, wing-shaped contour of refractory material, such as SiC, MgO formed. Due to the Coanda effect, the melt follows the contour of the Coanda profile and is at the same time deflected outwards from the center of the strip and downwards in the direction of the moving bath. This counteracts the constriction of the melt jet, this is therefore avoided.
- the velocity profile in the pool is clearly homogenized over the entire casting width.
- the special, geometric shape at the outlet of a pouring spout causes the outflowing melt to expand horizontally. This reduces the striation. This ensures u. a. the Coanda effect for an expansion of the melt flow and thus for a homogenization of the melt across the casting width.
- the kinetic energy must be as low as possible when the melt overflows from the casting line to the strip.
- the introduction of gas bubbles into the melt and, on the other hand, the generation of flow patterns is minimized.
- the lateral stratification during the overflow of the melt on the moving belt of a strip casting is reduced and improves the microstructure.
- the essential advantage of the invention is that the passive flow guidance through the Coanda profile supports the homogenization process on the basis of the magnetic stirrer.
- the new method is thereby inexpensive.
- the refractory form of the distribution device between continuous casting distributor and conveyor belt only needs to be changed.
- the dimension of the inductive stirrer is reduced with simultaneous use of the Coanda profile.
- the U. a. The principle based on the Coanda effect can be applied wherever free pouring streams are to be influenced by a passive flow without external influence only by shaping measures.
- the method can also be applied to strip casters for non-ferrous metals.
- the object of the present invention is further achieved by a device for strip casting with lateral flow of a molten metal with a casting spout over which the melt flows on a moving belt, wherein the refractory side wall at the exit region of the spout a streamlined, three-dimensional contour of an ellipsoid of revolution and / or Having wing.
- the refractory side wall at the outlet region of the casting snout is specially designed, three-dimensional (convex, concave), flight-like.
- the outlet of the pouring spout is preferably in the form of a flight and at the same time in the form of an ellipsoid of revolution and / or wing (2) in the direct casting direction x.
- the exact geometry of the Coanda profile depends, among other things, on the flow velocity of the melt on the casting spout.
- the widths of the pouring device and the conveyor belt are usually between 1.0 m and 2.0 m.
- the length of the pouring device is about 1 m.
- the distance from the casting spout to the treadmill, hence the drop height of the melt from the spout to the revolving belt, is about 20 mm to 80 mm.
- the speed of the treadmill is up to 30 m / min.
- the angle between the ladle and the treadmill is 0 ° to 20 °.
- the temperature of the melt depends on the steel composition. For Low Carbon Steel the temperature is 1550 ° C, for high alloy steels it is 1450 ° C.
- the method can be applied to copper, aluminum or zinc except on steel grades. strip casting are applied.
- the melt is copper, aluminum, zinc, LowCar- bon Steel or high-alloy steel.
- the refractory coating contains MgO or SiC.
- the melt flows out below the distributor, there may be another vessel, which represents the actual feeding and distributing device, in particular pouring spout, of the melt onto the moving lower belt
- the melt flows out of the distributor via the so-called immersion tube (SEN - Submerged Entry Nozzle) in the feeder, which calms and distributes the melt.
- immersion tube SEN - Submerged Entry Nozzle
- the shaping at the lateral outlet of the pouring spout is decisive.
- the last stretch of the refractory side wall at the exit area of the casting spout which can be up to about 30 cm long, is designed to optimize flow.
- the contour is formed like a flight in the direct casting direction. Due to this special contour, the melt follows a relatively long time, therefore without separation along the contour. This behavior is supported by the Coanda effect.
- the Coanda profile is similar to a wing on the aircraft flows from the front. At the same time, the melt is also continued after leaving the casting spout. The melt is transported as quietly as possible, at low speed and with low turbulence to the running sub-belt. The wing sticks out over the spout. By combining these two conditions, the Coanda profile has the form of a flow-optimized ellipsoid of revolution.
- FIG. 1a shows a plan view of a continuously expanding spout according to the prior art, shows a plan view of a pouring spout according to the invention, a side view shows an outlet according to the invention of the pouring spout,
- melt stream 7 already dissolves at the spout 1 at the point A down.
- the melt 3 constricts, thickening and it forms a strand that emerges from the spout 1 and strikes with high kinetic energy to the underlying, moving sub-belt 4 with side sealing.
- the lower band 4 moves in the x direction.
- the strand leads in the pool on the conveyor belt 4 to intensive, unwanted turbulence 5 or to areas that are not acted upon by melt 3.
- the turbulence 5 is described by the flow separation A and constriction 6 in FIG. 2, here at the shown a game of a water model.
- the lateral flow 7 has a higher momentum and a higher kinetic energy than the flow 7 in the middle of the band.
- the melt 3 therefore penetrates deeper into the melt pool of the conveyor belt 4, wherein the typical strands structure is maintained and a non-uniform velocity profile 8 is induced.
- the tress attaches itself to the side seal (insulation block chain) in the re-start point or stagnation point B. This process is illustrated by the laser-optical measurements in the mold pool of a Hazelett-Caster water model during the outflow without Coanda profile in FIG.
- melt 3 can even upstream against the transport direction x of the belt 4, whereby near the side seal relatively stable, disturbing flow patterns are generated, which may be retained in the continuous solidification under certain circumstances.
- Observations on a Hazelett caster in operation have shown that it is a highly transient process, with recovery point B moving upstream and downstream. This results in an uneven velocity profile 8.
- the spout 1 according to FIG. 1 b shows the general shaping according to the invention at the lateral outlet.
- the last stretch of the refractory side wall is formed like a flight.
- the Coanda profile 2 is formed over the spout 1 in the y-direction and at the same time also in the direction of the treadmill in the x-direction.
- a three-dimensional nale, wing-shaped and thus streamlined wing contour 2 created from refractory material.
- the melt 3 follows the wing contour 2 as a result of the coanda effect and is at the same time deflected outwards in the z direction and downwards in the y direction, therefore away from the strip center, as is additionally shown in FIGS.
- FIG. 3 b shows a laser-optical speed measurement in the water model, in which only one Coanda profile 2 was installed in comparison with FIG. 3 a. It becomes clear that the streaking is reduced.
