    摘要: A ROLLING MILL WITH TWO ROLLS HAS AN IMPROVED CONTROL ASSEMBLY WHICH COMPRISES ELECTROMAGNETIC OR PHOTOELECTRIC SENSORS WHICH METER THE GAP BETWEEN THE ROLLS WHILE REMAINING OUT OF CONTACT WITH THEM. THE OUTPUT OF THIS SENSING ARRANGEMENT IS COMPARED WITH A REFERENCE VALUE TO YIELD AN ERROR SIGNAL WHICH IS FED TO AN ADJUSTMENT MECHANISM TO CHANGE THE ROLLER GAP IF NECESSARY. FURTHER SENSORS FOR METERING A BENDING IN THE ROLLS CAN BE PROVIDED AND COUPLED WITH A DEVICE FOR STRAIGHTENING THE ROLL. IN ADDITION A GUAGE MEASURING THE THICKNESS OF THE ROLLED WORKPIECE CAN BE USED TO PROVIDE A CROSS CHECK ON THE FUNCTIONING OF THE APPARATUS.

    摘要: TO ADJUST THE ROLL GAP OF A ROLLING MILL HYDRAULIC PISTON AND CYLINDER ASSEMBLIES ACT BETWEEN THE HOUSINGS OF THE MILL AND THE ROLLS, AND ECH ASSEMBLY HAS ITS OWN POSITIONAL CONTROL SYSTEM WHICH IS ARRANGED TO MAINTAIN THE PISTON AT A DATUM POSITION RELATIVE TO ITS CYLINDER AND AN AUTOMATIC CONTROL SYSTEM SUCH AS A GAUGE METER DETECTS DEPARTURE OF THE STRIP GAUGE FROM A REQUIRED VALUE AND ADJUSTS THE DATUM POSITION OF AT LEAST ONE OF THE PISTON AND CYLINDER ASSEMBLIES TO COMPENSATE FOR THE VARIATION IN GAUGE. THE PISTON AND CYLINDER ASSEMBLIES MAY REPLACE THE CONVENTIONAL SCREWDOWN SCREWS OF THE MILL OR ALTERNATIVELY THEY MAY ACT IN SERIES WITH THE SCREWS.

    摘要: A ROLLING MILL HAS A GAGEMETER CONTROL ON SUBSTANTIALLY EVERY MILL STAND. AN X-RAY GAGE DEVIATION SIGNAL IS FED THROUGH AN ISOLATOR UNIT WHICH PROVIDES A WIDE DEAD-BAND WITHIN THE GAGE TOLERANCE FOR A PARTICULAR ORDER. IF THE GAGE DEVIATION SIGNAL EXCEEDS THE WIDTH OF THE DEAD-BAND THE DEVIATION SIGNAL IS INTEGRATED IN A HIGH GAIN INTEGRATOR AND USED TO CHANGE THE SET POINT OF THE GAGEMETERS ON EACH GAGEMETER CONTROLLED MILL STAND UNTIL THE X-RAY GAGE DEVIATION RETURNS WITHIN THE DEAD-BAND PROVIDED BY THE ISOLATOR UNIT.

    摘要: A setting means sets variables for expressing the process model, a target thickness value of the rolled material, a target interstand tension value of the rolled material, variables for responses of the thickness and the interstand tension and variables for adjusting the responses of a control system for controlling the thickness and the interstand tension. A control gain arithmetic means obtains control gains as numeric values by substituting the set variables into predetermined control gain operation expressions. A control arithmetic means calculates the speed command values and the roll gap command values for causing the thickness to follow up the target thickness and the interstand tension to follow up the target interstand tension while reducing an interaction between the thickness and the interstand tension by use of the calculated control gains.

    摘要: According to this invention, a rolled sheet rolled by a reduction roll of a rolling mill is divided into a plurality of areas in a direction of its width, and sheet flatness or thickness values are measured in the plurality of areas. Bending forces, leveling value, shift amounts, and the like applied, by actuators respectively arranged at drive and work sides of the reduction roll, from the drive and work sides of the reduction roll are calculated in accordance with the sheet flatness or thickness measurement values and influence coefficients of the actuators. The actuators on the drive and work sides of the reduction roll are independently operated in accordance with these operation amounts.
