Example Embodiment

[0042] In the case of omitting the original rolling mill stand, figure 1 Two support rolls 31, 32 and two work rolls 33, 34 between the support rolls are shown, where the roll gap 12 of the work rolls is adjustable. Above and below the rolled strip 10 coming out of the rolling mill (from left to right in the figure), there is a rolling zone composed of rolls 31, 32, 33, 34 and the rolled strip 10. 11. The leaving rolled strip 10 should be shielded from the rolling zone 11.

[0043] To this end, first, the rolling zone 11 surrounded by water mist has been partially separated from the finished rolled strip 10 by a fixedly installed upper guard plate mechanism 1 and a fixedly installed lower guard plate mechanism 2. The movable guard mechanism supplements the fixed guard mechanism 1, 2.

[0044] Above the rolled strip 10, this supplement is a movably formed upper strip guide 3, which includes a strip blowing mechanism 4 driven by a fan and integrated with a low-pressure nozzle 7. Th...

Abstract

In addition to good flatness and optimum thickness tolerances, the manufacturer's preferred quality requirements for cold-rolled strip products also include that the strip should be dry at the exit of the cold-rolled strip rolling plant. According to the present invention, an improved device that is arranged in the exit area of ​​the rolling mill and has a fixed guard plate mechanism, a movable guard plate mechanism, a roll body blowing mechanism, a rolling strip blowing mechanism and a smoke suction mechanism is proposed. Above the strip (10) there is an upper strip guide (3) with integrated upper roller driven by a fan and with the aid of a low-pressure nozzle (7) and in the form of a slot nozzle (6). There is a strip blowing mechanism (4) for the body gap seal (5), and an independent suction mechanism (16) integrated with a lower strip guide plate (17) is provided below the rolled strip (10).

Description

technical field [0001] The invention relates to a device for keeping cold-rolled strip dry at the exit of a rolling mill, the device having means for drawing rolling fluid in the strip exit area and / or for blocking liquid sprayed on the surface of the strip, where these In addition, the mechanism that cooperates to form a functional unit consists of a fixed guard plate mechanism and a movable guard plate mechanism arranged above and below the rolled strip, a roll body blowing mechanism, a roll body gap seal and a smoke suction mechanism composition. Background technique [0002] In addition to good flatness and optimum thickness tolerances, the manufacturer's preferred quality requirements for cold-rolled strip products also include that the strip at the exit of the cold-rolled strip rolling plant should be dry to avoid surface Defects such as stains allow the strip to continue to be processed. [0003] Various plant measures are known in the prior art, the aim of which is...
