Definitions
- the invention relates to a pouring nozzle for a horizontal strip casting plant, in particular for the casting of steel strip. In such casting plants must be applied from the nozzle, which forms a pouring channel, the liquid steel on a cooled endless belt.
- Such a casting nozzle is known from “Direct Strip Casting” (DSC) - Option for the Production of New Steel Grades "- steel research 74 (2003) no. 11/12 p. 724-731.
- a web of refractory material projecting transversely to the flow direction is arranged in the direction of flow, first at the top and then at the bottom of the pouring nozzle channel. Both webs form a weir in order to be able to retain in the sense of the effect of a siphon possible small slag residues and oxides in the melt.
- the transfer of the liquid steel on the cooled endless belt is slidably along a slope in the outlet area.
- the object of the invention is to improve the known casting nozzle to the effect that the melt distributed evenly when hitting the endless belt in the transverse direction.
- the object is achieved on the basis of the preamble of the main claim with the features of the characterizing part.
- the casting nozzle according to the invention is characterized in that seen in the flow direction of the hollow cross-section of the hollow block in the outlet area is uniformly reduced towards the outlet and the end face of the bottom is formed to the surface of the endless belt in such a way that the melt is perpendicular to the endless belt.
- the front side of the floor can be formed vertically or provided with an undercut.
- the cross-sectional reduction is preferably carried out by reducing the clear height distance.
- An increase in the floor compared to the ceiling has proven to be a favorable option.
- the distance reduction can be realized particularly simply if it takes place linearly.
- the desired effect is achieved without problems if the surface of the floor rises linearly as far as the outlet edge, viewed in the flow direction.
- the hollow block can be made in one piece or in several parts of separate elements.
- a multi-part of the hollow block may consist of separate floor element with a one-piece consisting of ceiling and two side walls hood or a separate ceiling element, a separate floor element and two separate side elements.
- the rectangular or undercut arrangement of the end face of the bottom element of the casting nozzle with respect to the surface of the endless belt causes a better distribution of melt on the endless belt.
- the outflowing melt thus almost hits perpendicular to the endless belt and generates an additional transverse pulse.
- the height from the outlet edge to the endless belt should preferably be 30 mm.
- the slope of the run-up slope of the floor element is linear, similar to a ramp.
- the extent of the increase in the flow direction should be at least 30 mm, preferably it is> 50 mm.
- the outlet edge is provided with a chamfer. This chamfer simultaneously reduces the wear on the highly stressed outlet edge.
- the pouring nozzle according to the invention is explained in detail.
- FIG. 2 shows a cross section along the line B-B in FIG. 1,
- Figure 1 shows in a longitudinal section and Figure 2 in a cross section schematically an embodiment of the pouring nozzle according to the invention 1. It is designed as a narrow rectangular hollow block and is composed in this embodiment of a ceiling element 2, a bottom element 3 and two side elements 4, 5 (FIG 2). All these parts 2 - 5 are made of refractory material, preferably ceramic and form a horizontally lying rectangular channel. 6 As known from the prior art, the bottom element 3 has a web extending into the channel 6 and extending transversely to the flow direction, which forms a so-called lower weir 7.
- the pouring nozzle 1 is connected upstream of an inlet channel 8, which is connected to a distributor, not shown here.
- weirs 7, 10 act together like a siphon and are supposed to retain any slag residues and oxides still present in the melt.
- Both weirs 7, 10 can be arranged both in the pouring nozzle 1 and in the inlet channel 8 or as shown here, the upper weir 10 in the inlet channel 8 and the lower weir 7 in the pouring nozzle. 1
- the inlet channel 8 is surrounded by a frame 22 made of metal, which is tongue-like at the end to clamp the adjacent casting nozzle 1 can.
- the surface of the bottom element 3 has a run-on bevel 11, the rise of which takes place linearly and which extends up to the outlet edge 12.
- the spout is not provided with a bevel, but rather the end face 21 of the bottom element 3 is at right angles with respect to the surface of the endless belt 14.
- the run-on slope 11, viewed in the direction of flow, has an extension 18 of at least 30 mm, preferably> 50 mm.
- the beginning of the run-on slope 11 is provided in the immediate vicinity of the lower weir 7.
- this is this provided with a chamfer 23.
- the height 19 from the lower edge of the chamfer 23 to the surface of the endless belt 14 is preferably 30 mm.
- the end face 21 of the bottom element 3 opposite the end face 26 of the ceiling element 2 has a projection 20.
- FIG. 3 shows, in a section C - C of FIG. 2, a further measure for distributing the outflowing melt 13 more uniformly on the endless belt 14 in the transverse direction.
- the bottom element 3 in both edge regions of the projection (20) has a sloping in the flow direction inclined surface 24, 25.
- the respective inclined surface 24, 25 forms a triangle whose one corner is formed by the beginning of the starting bevel 11, the second corner by the outlet edge 12 and the third corner by the end face of the respective side element 4, 5.
- This supernatant 20 should be at least 10 mm in order to be able to act early on the outflowing melt.
