Definitions
- the invention relates to a device for influencing the Friction between an upper and a lower roller a mill stand of a hot strip mill or a cold strip mill and a method for rolling a rolling stock by influencing the friction between an upper and a lower roll of a roll stand.
- the invention has for its object a device create that allows both between the top of the tape Rolled good and the upper roller as well as between the underside of the strip the rolling stock and the lower roll almost the same friction conditions arise to improve the efficiency of the rolling process as well reduce wear on the upper and lower rollers and continue to be the one that often occurs with larger thickness reductions To dampen the tendency to vibrate.
- a device which consists of a Spraying device arranged on the inlet side of the roll stand to spray a defined amount of liquid in the direction of the Roll gap and a control device for quantitative determination and dispensing this liquid, with a as a controlled variable pre-determined or calculated size in connection with the actually rolling torque of the lower and / or the upper roller is provided.
- the invention further provides a method for achieving the object Rolling the rolling stock by influencing the friction conditions between an upper and a lower roll of the roll stand, in which the strip top and / or the strip underside of the rolling stock on the inlet side of the roll stand with a spray device a defined amount of liquid is wetted and a control device quantitative determination and delivery of the liquid regulates, with a pre-determined or calculated control variable Size in connection with the actual rolling torque of the lower one or / and upper roller are provided.
- An upper spray device is preferably used for this purpose and a lower spray tube on the inlet side of the scaffold in the Close to the roll gap in the area of the upper or lower roll arranged.
- the spray tubes themselves preferably have a uniform shape or, for example, parabolically distributed nozzles whose jet direction aims directly into the roll gap.
- the approximation of the friction conditions between the upper and the lower roller opposite the rolling stock by changing the amount of liquid, preferably water or achieved a water-oil mixture in the area of the roll gap is injected.
- the amount of liquid that goes in the direction of the roll gap is injected, a control device determines. This control device is also intended for the effect of to regulate the two spray tubes independently of one another, d.
- This control device also includes Transducers, especially the torques actually occurring in each case on the upper and on the lower roller of the roll stand notes.
- the torque difference determined from these two Torque values is calculated, is then proportional the amount of liquid dispensed.
- This amount of liquid must therefore also be so large that, on the one hand, none is impermissible high cooling of the upper as well as the lower band surface occurs, and that, on the other hand, a sufficient control range for approximation the friction in the roll gap is available.
- the torque detection is preferably done by, on the drive spindles of the rollers arranged transducers.
- the control device also includes control valves, which accordingly the previously determined or calculated torque value become.
- control valves which accordingly the previously determined or calculated torque value become.
- Preferably two control valves are provided, the first control valve for the quantitative delivery of water and that second control valve provided for the quantitative delivery of oil are.
- the first control valve for the quantitative delivery of water and that second control valve provided for the quantitative delivery of oil are.
- the water-oil mixture has a different effect the rollers and thus different changes in the coefficients of friction between the top of the belt and the top roller and between the bottom of the belt and the lower roller.
- the sign of the respective torque difference or the deviation from a defined Target torque difference provides the signal for the direction in which the valve must be adjusted.
- control valve It is also possible to use only one valve as a control valve.
- the other control valve is in a defined basic position fixed, which is approximately in the middle of the range that the controllable Valve for the rolling program enough control range in both Provides directions.
- the position of this valve can be adapted to the respective rolling program.
- the valves for the upper and lower spray tube adjusted in the opposite direction from a basic position to take advantage of the maximum possible control range.
- the invention further provides that the composition of the water-oil mixture for roll gap lubrication is included in the control.
- the sum of the Torques on the spindles are measured above their minimum as Signal to optimize the composition of the water-oil mixture to be used.
- the device 1 consists of a Spray device 2 and a control device coupled to it 3.
- the spray device 2 itself includes, each in the areas 4 and 5 of the upper and lower rollers 6 and 7 arranged Spray pipes 8, 9 arranged parallel to the roller axes, which their circumference nozzles 10 which are arranged so that a flow of water or water-oil mixture through the pipes the nozzles 10 in the direction of arrow 11 towards the roll gap 12 is directed.
- the spray tubes 8, 9 are with a line system 13 connected. In the exemplary embodiment (cf. FIG. 1) open into each Line 13a two lines, of which a first line 13a 'to Guiding water and a second line 13a '' for guiding Oil are provided.
- the controller 3 processes the information via the transducers 19, 20 (further transducers are in broken lines are indicated.) These sensors are, for example, on the drive spindle 21 (Fig. 2) for measuring the current torque arranged.
- the controller 3 controls the control valves accordingly 14, 15, 16, 16, 17 so that a calculated amount of liquid in the Reaches the area of the roll gap 12 and is thus ensured that in this among themselves the same frictional relationships between the Top 23 of the belt 25 and the upper roller 6 and between the bottom 24 of the belt 25 and the lower roller 7 achieved become.
- the upper and lower rollers 7, 8 are shown as in Fig. 2, driven by main drive spindles 21, 22.
- a control valve controlled by the controller while the position the other control valve from a higher-level computer system is adapted to the respective rolling program. It is also conceivable that the controller controls the other control valve and the higher one Computer system that a control valve.
- the liquid requirement for the lower roller is always greater than that of the upper roller because there is also liquid on the top of the belt accumulates by the roller cooling device for the top roller comes, and the side of the wipers on the belt surface If the other valve is regulated, too much water will drip on the belt surface.
- the other valve would then be used to compensate arranged that the effect of the sufficient liquid present on the top of the band by adding more water to the Underside of the band is compensated.
- the uncontrolled Liquid flowing on the top of the belt is included in the control.
- the amount of basic fluid is in the middle of the control range for both control valves determined by the computer system.
