Definitions
- the invention relates to a device for cooling a metal strip with arranged in transverse rows to the tape feed direction below the sheet metal strip nozzles for ceremoniessprühende on the underside of the belt coolant.
- the invention is therefore based on the object, a device for cooling a metal strip of the type described in such a way that the metal strip can be uniformly cooled over its width, despite high cooling rates while avoiding attributable to differences in thickness longitudinal stripes.
- the invention solves the problem set by the fact that the jet nozzles designed as nozzles form a common central jet area per transverse row and that in the spray area of the nozzles laterally adjacent to the plate covers are provided.
- the covers are aligned with the underside of the sheet metal.
- the side covers which are aligned with the band underside form a spraying surface which extends beyond the band width and which enables comparable reflection conditions for the sprayed-on cooling liquid beyond the edge of the band.
- the covers can be displaced transversely to the feed direction as a function of the longitudinal edge of the sheet metal strip, which can be realized in a simple manner constructively, for example, with a scan of the tape longitudinal edges and acted upon by this scan control device for the actuators of the covers.
- the spray range of the nozzle in the tape feed direction can be limited by a provided below the metal strip deflection device for the cooling liquid.
- the sprayed from the nearest nozzle transverse row against the deflection liquid content is thus derived from the tape before it strikes the lower side of the belt, which creates advantageous design conditions in terms of the limitation of the spray range, especially if the nozzles of the front and rear in the tape feed direction transverse rows in their inclination to a can be adjusted in the direction of the transverse row axis.
- the device shown for cooling a sheet-metal strip 1, which is conveyed for example from a continuous furnace 2 by means of a supporting air cushion, has a plurality of transversely to the feed direction 3 of the sheet metal strip 1 extending spray bar 4 and 5 below the sheet metal strip 1, wherein the flat nozzle formed as nozzles. 6 the nozzle bars 4 and 5 are arranged in mutually offset transverse rows, as shown in FIG. 1 can be removed. Within each transverse row, the nozzles each form a common central jet area 7, as indicated in phantom in FIG. 2. This means that the spray cone 8 of the flat jet nozzles 6 overlapping each other in the region of the sheet metal lower side, shown in phantom in FIG.
- lateral coverings 10 adjoin the longitudinal edges of the sheet-metal strip 1 along the cooling path defined by the nozzle bars 4 and 5 on both sides of the sheet-metal strip 1.
- These covers 10 are aligned with the lower side of the belt, which is thus widened in terms of Aufsprüh Structure by the covers 10.
- the side covers 10 do not only secure themselves over the Band edge continuing away, constant reflection conditions for the sprayed coolant, but also prevent coolant in the longitudinal edge region of the sheet metal strip 1 reaches the top of the sheet metal.
- the covers 10 are slidably mounted in transverse to the feed direction 3 guides 11 and connected to actuators 12, which according to FIG. 1 via a control device 13 in Depending on the longitudinal edge of the sheet metal strip 1 are controlled.
- the longitudinal edge profile of the sheet-metal strip 1 is scanned via sensor 14, with the output signals of which the control device 13 is acted upon.
- this cooling section is limited by provided below the sheet metal strip 1 deflecting means 15 for the cooling liquid.
- These deflection devices 15 each consist of a boundary wall 16 with a spacing crossover deflection profile 17, as can be seen in particular from FIG.
- the spraying region of the edge-side nozzle bar 4 can be structurally determined because the portion of the cooling liquid sprayed against the deflecting device 17 is discharged from the spraying area so that interference due to reflections of the cooling liquid on walls of the cooling device provided in this area is avoided.
- the pivotability of the edge nozzle bar 4 is indicated in the drawing by pivot axes 18.
