Definitions
- the invention relates to a device for blowing off a roll stand leaking belt with a separate belt edge blow-off.
- the invention is based, with a generic tape blowing device the task to improve the belt edge blow-off.
- the band edge blowing and the tape blowing device are connected to one another in terms of control technology.
- the invention is based on the idea of the valve control which is required anyway the middle and edge zones of an existing band blowing device use and automatically feed the compressed air to the belt edge area to blow, without any additional manual intervention or drive to adjust or have to see the bandwidth to be driven, so that the band edge blow-off starts automatically with the band blow-off.
- One embodiment of the invention provides that the band edge blow-off Has nozzle bars with several nozzles, the nozzle bar inputs with each connected to the valve outlet of the valves of the existing band blow-off device are.
- the nozzle bars are in the area of the edge zones of the band blowing device arranged.
- the blow-off nozzles of the belt blow-off device are so controlled that only the nozzle that lies next to the last peripheral zone nozzle, i.e. is outside the existing blow-off area, is acted upon and so that the tape edge is blown off and dries.
- nozzle bars in series have successive pistons, which have a common Acting agent is assigned.
- This can be a centrally located spring be, which is supported against a cover of the nozzle bar and the pistons in the Initial or non-operational position in its closed, the air outlet holds in the blocking position.
- the ones arranged in the nozzle bar, horizontal Pistons that can be moved against one another thus close in the pretensioned state or by the application of the nozzle exits; the number of nozzles Belt edge blowing depends on the number of edge zones or the Nozzles assigned to edge zones. With active belt edge blowing, only the Nozzle connection, which is next to the last activated peripheral zone nozzle, with compressed air acted upon.
- the compressed air not only shifts the first piston, but also also all other pistons against the force of the loading agent. This will The passage to the first nozzle is clear via the piston ring surface and the compressed air of this Nozzle is blown against the belt edge while all other nozzles continue are locked.
- a preferred embodiment of the invention provides that the pistons are the same Have diameters and with pins of different diameters are formed, in such a way that the diameter of the one outer Rise the piston to the other outer piston. Define the individual tenons thus determined stepped piston ring surfaces of different sizes. The one from the Edge zone of the normal band blower most distant pistons of the nozzle bar has the smallest pin diameter during which the edge zone at nearest piston of the nozzle bar has the largest diameter. This makes it possible to achieve that even on all if necessary Nozzle bar connections to the compressed air, but only one specific nozzle is released and blows on the belt edge; the others, however, do not stay required nozzle outlets closed.
- the band blowing device 1 shows a circuit diagram of a band blow-off device 1, which is not shown here shown rolling mill is connected downstream, with which runs out of the stand Tape is dried.
- the band blowing device 1 consists of a central zone 2 as well as two peripheral zones 3, 4. Zones 2, 3, 4 each point to the band blowing several nozzles 5.
- a compressed air source 6 supplies the valves 7 to 13 Bandabblasvortechnisch 1. Via the valve 7, the nozzles 5 of the Center zone 2 and selectively the nozzles 5 of the edge zones 3, 4 via the valves 8 to 13 pressurized with compressed air.
- Each exit (highlighted by a black Point) of valves 7 to 13 is additionally with nozzle inputs of two - only represented schematically as a black box - nozzle bars 14, 15 one Band edge blow-off 16 connected, one at each Band edge side is arranged.
- FIG. 2a the nozzle bar 14 shown in FIG. 1 only as a black box is shown as Detail shown in more detail in longitudinal section.
- the nozzle bar 14 is at the top with seven Nozzles 17 to 23 equipped, the nozzle bar inputs 24 to 30 are opposite.
- Pistons 31 to 37 are located in series in the nozzle bar 14 arranged, which in the embodiment by a compression spring 38 against one Cover 39 are biased and the nozzles 17 in the inoperative position shown close to 23. All pistons 31 to 37 have the same piston diameter, while their pegs 40 to 46 - starting from the outer one, left in the figure Piston 37 - have increasing diameters.
- FIG. 2b shows the nozzle bar 14 with an active band blow-off device 1 for one the smallest strip of metal strip to be rolled.
- Compressed air flows, controlled via the valve 7 (see FIG. 1), through the nozzle bar inlet 24 and presses the outer right piston 31 over its annular surface 47 and at the same time all others Pistons 32 to 37 against the compression spring 38; For this actuating movement is in a central bore receiving the pistons 32 to 37 of the nozzle bar housing, a free displacement 48 is available. The passage to Nozzle 17 is released, and thus the compressed air can hit the belt edge be blown.
- FIG. 2c shows the nozzle bar 14 in an operating position in which only the nozzle 21 blows onto the belt edge, although the nozzle bar inputs 24 to 28 of the nozzles 17 to 20 arranged on the right via the valves 7 to 11 with compressed air are acted upon.
- the compressed air flows through the beam inputs 24 to 28 and presses the piston 35 over its annular surface 47 and also the pistons 36, 37 on the left of the nozzle 21 to be switched on nozzles 22, 23 against the spring 38.
