Definitions
- the invention relates to a combined control system for generating defined product properties when rolling steel grades in the austenitic, mixed austenitic-ferritic and ferritic range using a measuring method for determining the roll gap of a work roll pair by detecting the absolute position of the support or work rolls on the respective
- the gauge method has been used for thickness control for many years.
- the strength of the rolling stock (C mat ) in the working area of the roll stand is linear
- Characteristic has, that is a larger or smaller Waizkraft, neglecting the temperature compensation at the working point, a measure for a larger or smaller pass reduction in the roll gap
- Thickness control allowed With this method, the deflection of position sensors is measured, which correct directly with the roll gap opening, so that a value corresponding to the rolling stock thickness is obtained. In the case of a four-high or six-high stand, this can be the springing-up or change in position of the support roller, which is measured directly.
- a corresponding measuring system is in the German
- the Wear and the thermal crowning of the rolls can be done with this system a more precise thickness control than before according to the gauge gauge.
- profile, flatness and contour control is not possible with the known system; numerous other systems and methods are known for this, such as, for example
- the final rolling temperature is set to the desired value in a continuous rolling mill with a given pass acceptance distribution by regulating the rolling speed and the interframe cooling
- Rolling temperatures inter alia, reached by cooling phases between the rolling passes
- the object of the present invention is to roll steel grades in different temperature ranges on a reversing rolling mill with at least one or a continuous rolling mill with at least two
- a control system which, relative to the measured absolute position of the rolls, by means of sensors arranged alongside the roll, the upper edge of the upper and lower edge of the lower roll in segments over the bale length recorded that the measurement results of a model that takes into account the influences of the bending and roll setting systems, the deflection of the rolls, the flattening between the rolls, the flattening between the work roll and the material to be washed, and the wear and thermal stability of the rolls, into one Intervene in suitable regulations which influence the rolling gap and the rolling stock geometry and which, in addition to the required absolute thickness, brings about the required thickness profile and the flatness criteria.
- Embodiments of the control system according to the invention are defined in the subclaims
- This rolling mill (see Fig. 1) consists of at least three consecutively arranged Ho ⁇ zo ⁇ tal frameworks 2 to 3 (quartos or / and sextos), each of which is equipped with hydraulic adjustments 4.
- the work rolls are provided on the inlet and outlet sides with a device 5 with which Controllable over the width and in intensity by means of a cooling and / or heating medium without contact or contact, the roller shape can be influenced.
- feed systems 7 are arranged below or above the wipers, through which width a lubricant can be controlled on the roller or in the nip is sprayed in front of and behind the rolling mill and between the stands, devices 9 can be present with which the width and intensity can be controlled by means of a cooling and / or heating medium without contact or contact, the material temperature can be influenced, the last and possibly also the penultimate Scaffold is with the ate so-called OGCC system 8
- a temperature measuring point 10 is arranged in front of each stand with which the rolling stock temperature is measured across the width and / or at points.
- a measuring station 11 is installed behind the last stand, which has both the temperature and thickness profile and the flatness and width Surface quality recorded
- the rolling stock 1 enters the first stand and leaves the road from the last stand 3.
- the rolling temperature in the passes can be in the austenitic, mixed austenitic-ferritic and / or ferritic range
- the roll influencing systems 5, 7 and the rolling stock influencing systems 9 can be used to set the respectively required rolling stock temperatures which have the required mechanical properties
- the roll gap shape can also be influenced with the systems 5 7 in addition to the mechanical setting systems, which is recorded with the system 8 as a measuring element, so that suitable controls can intervene which, in addition to the required absolute thickness, also have the required thickness profile and pianism characteristic
- OCC Optical Gauge & Crown Control
- sensors 24 are arranged above the length of the bale and measure the actual profile shape in segments Sensors are mounted on a carrier. Because this carrier grinds on sliding shoes on the roller, the distance to the roller is constant.Therefore, sensors with a high resolution and a small measuring range can be used, e.g.
- a defined measuring edge 23 is attached to these slide shoes, which is used for optical position measurement.Dh by means of the optical position measurement (measuring edge 23), the absolute position of the support rollers is detected and, relative to this, the upper edge or lower edge of the sensors (24) Support rollers over the length of the bale
