Definitions
- the invention relates to a device for measurement load-dependent deformations of in strip rolling stands built-in rollers with reference to the roller longitudinal axis.
- EP 1 216 766 is one non-contact contour measuring device for measuring the geometric bale shape of built in strip rolling stands Rolling known in the rolling process.
- the contour measuring device is with a longitudinal beam extending over the length of the roller equipped, on which a variety of transverse to the longitudinal axis cooled, non-contact distance sensors, especially eddy current sensors, with a lateral distance are arranged to each other. With such measuring devices one is able to determine the state of wear and the thermal To measure bales of the rollers.
- a measurement of the measuring point opposite roll gap is however with these Measuring devices not possible, especially considering the through weight, rolling and bending forces as well as through the The presence of any intermediate rolls affected Measurement results.
- Roll gap measuring devices such as those from the US 3,102,960, DE 29 52 232 A1 and EP 0 250 768 A2 are known, allow a measurement of the roll gap under load or in the band area under load.
- the roll loads such as forming force, Bending force of the rolls to influence the roll gap, Stabilizing force and weight-related bending line
- a roll gap adapted to the rolling process to adjust, where in addition to parabolic bending lines Can set bending lines with parabolas of higher order.
- Example will be on the influence of positive and negative Bending noted in the rolling process. Like all roles are under deflecting the influence of loads is also subject to Example of a backup roller under the applied forming force a deflection. This has the consequence that the roll gap opens in the middle of the band; it therefore becomes a faulty tape a mid rise. Is the knowledge of the Bending line of the backup roll in front, for example, can be next to others Actuators also by a backup roller with hydraulic adjustable bales can be compensated.
- the invention has for its object a device for measuring the load-dependent bending line of in To develop built-in rolls.
- Measuring cartridges can be selected with reference to the longitudinal axis of the roller.
- Measuring cartridges with sensors for recording changes in length or mechanical alternating voltages are expediently in one of the roll longitudinal axis or axis of rotation of the Install rollers with spaced longitudinal bore.
- Measuring cartridges with Piezoelectric sensors can be divided into a central longitudinal bore of the roller can be arranged.
- Laser / CCD arrays can be unlike the ones mentioned earlier Sensors only at their installation location deviations from the geometric Represent the longitudinal axis of a roller, but are able to do so statements about vibrations and eccentricity deviations in the form of a locus.
- Fiber-optic sensors can also be used.
- the sensors transmit the signals through the stand state-of-the-art transmission equipment, for example optical, electrical, magnetic, capacitive or radio-technical type.
- a major advantage of the measuring cartridge according to the invention with the sensors is in front of mechanical loads and Dirt-protected installation in the roller can be seen.
