Definitions
- a device of the type mentioned is known from EP 1 339 891 Bl.
- the trunk is extended at its submerged part on each side of the metal strip by an inner wall which is aligned to the surface of the limited by the trunk liquid seal and whose upper edge is below this surface.
- These inner walls bound with the wall of the trunk two outflow spaces for the liquid metal.
- a pump is connected to the two outflow spaces via suction lines in order to keep the level of liquid metal in these spaces at a level below the surface of the liquid seal, thus causing a natural drainage of the liquid metal from this surface to the discharge spaces.
- the level of liquid metal in these outflow spaces is detected and maintained at a level below the surface of the liquid seal such that the drop height of the liquid metal in the outflow spaces is greater than 50 mm to counteract the buoyancy of the metal oxide particles and the intermetallic compounds
- Pipe is connected to the lower region of each of the outflow spaces, wherein in each of the outflow spaces, the connection point of the suction line of the pump is above the junction of the pipe connected to the reservoir.
- the reservoir forms a liquid metal buffering capacity for each of the outflow spaces.
- the reservoir with drainage spaces across the pipeline forms a system of communicating tubes in which the liquid metal level is typically at the same level. The reservoir is doing with a
- Liquid metal level detector equipped.
- Reservoir and liquid metal level detector in industrial use susceptible to interference, as it is within the reservoir to a significant slag formation.
- the cleaning action required to remove the slag from the reservoir is unsatisfactory from the point of view of occupational safety.
- Draining chamber ensured, regardless of the height of fall of the upper slag in the drain chamber. This results in the following advantages: • The trunk can be swiveled and telecopied without disturbing the top slag removal.
- Flow chamber can flow, wherein the respective passage opening is arranged lower than the overflow edge, and wherein at least one of the through holes in the region of the top of the metal strip and at least one further of the
- the at least one passage opening or a plurality of passage openings are provided in the wall of the trunk or the outer wall of the drain chamber, whereby a
- the through openings are formed so that their respective central axis with the perpendicular to the plane of the
- the passage openings may be formed by pipe sockets (pipe sleeves) and / or provided with guide elements for guiding the metal melt flowing into the discharge chamber via the passage opening.
- guide elements may be, for example, pipe sections, pipe bends or flat guide elements, such as baffles or vanes. The guide elements can thereby within the Drain chamber may be provided in particular at or in the vicinity of the passage openings.
- a further embodiment of the device according to the invention is characterized in that the overflow edge of the overflow wall in the overflow direction is rounded.
- This embodiment favors a mode of operation in which the upper slag and liquid molten metal drain relatively smoothly, preferably as laminarly, over the overflow edge into the drainage chamber.
- the trunk as laminar a surface flow as possible is desired since particles, dusts or melted splashes coming from the molten bath surface, e.g. due to turbulent flows in the protective gas range of the trunk leak on the incoming metal strip settle and can lead to coating errors.
- the device according to the invention extending on the underside of the metal strip portion of the overflow wall on the wall of the trunk side facing a material additive which defines a vertical edge or a positive slope in the direction of the Rüsselwandung extending edge.
- At least one passage opening is provided at the lowest point of the discharge chamber or at the beginning of the suction line, through which liquid molten metal can flow from the molten bath into the suction line.
- Melt bath level adjustable adjustable. Also, by the movement (change in position) of the trunk relative to the molten bath, the distance of the upper edge of the overflow wall with respect to the molten bath is adjustable.
- Characteristic can be determined and set.
- an advantageous embodiment of the device according to the invention is characterized
- the device is equipped with a control or regulating device which is prepared to determine a measured variable which is proportional to the height difference between molten bath level and overflow edge on the basis of a measuring signal of the displacement sensor and a measuring signal of the molten bath level measuring measuring device, and also prepared is to control or regulate the performance of the pump based on said measure.
- a control or regulating device which is prepared to determine a measured variable which is proportional to the height difference between molten bath level and overflow edge on the basis of a measuring signal of the displacement sensor and a measuring signal of the molten bath level measuring measuring device, and also prepared is to control or regulate the performance of the pump based on said measure.
- Overflow edge is.
- an additional volume flow which depends on the number and size of
- (Raising) of the pump power is used, for example, at the beginning of the continuous coating process to bring the level in the drain chamber to a lower level compared to the molten bath, whereby the surface flow in the trunk is improved or reinforced in the direction of the drain chamber.
- a further embodiment of the device according to the invention is characterized in that the bottom of the drain chamber is arranged with a slope in the direction of the suction line. This promotes the removal of slag from the trunk.
- the device according to the invention can be provided with monitoring devices for securing the process stability as well as for documenting the
- the proboscis is provided with an optical camera for observing the molten bath level within the spit.
- the discharge chamber is preferably provided with a measuring device having a measuring rod for determining the melt bath level in the discharge chamber.
- annular discharge chamber 11 are connected.
- the frame-shaped overflow wall 8 of the drain chamber 11 limits the outlet opening of the trunk 6, through which the belt 5 runs in the direction of the deflection roller 3.
- the band upper-side portion of the overflow edge is denoted by the reference numeral 9 and the band-underside portion to the
- annular discharge chamber 11 with the frame-shaped inner wall 8 corresponds to the embodiment shown in FIG.
- the section of the overflow wall 8 which extends on the underside of the band 5 is additionally provided on the side facing the wall of the trunk end piece 7 with a material additive 25 which defines a vertical flank.
- the added material 25 eliminates or closes an undercut throat between the overflow wall 8 and the bottom of the drain chamber 11.
- the additional material 25 may also have a through hole (flushing bore) 15 and be formed for example in the form of a partition. By this partition wall or the additional material 25, a negative slope, ie a throat enclosing an acute angle, is avoided on the bath-underside section 10 of the overflow edge.
