摘要： PURPOSE:To detect the amount of the camber with a simple method by photographing the shape of a plane of a steel plate by an infrared camera to obtain the amount of the camber. CONSTITUTION:An operating/processing device 35 takes the temperature of a steel plate with a thermometer 33, and selects and attaches a filter corresponding to the temperature to infrared cameras 31, 32. Photographic signals except for the signal of the steel plate are removed by the filters. The cameras 31, 32 with filters are driven by driving motors 37, 38 to photograph the steel plate with a predetermined pitch in a longitudinal direction. The device 35 obtains the rotational angle when two images of the steel plate at one end in the longitudinal direction are overlayed on each other and the rotational angle when two images of the steel plate at the other end are overlayed on each other. The amount of the camber is detected on the basis of the rotational angles and output to a host computer.

摘要： PURPOSE:To make it easy to measure the rolling width by detecting the inclination of the radiation face and the intensity of radiating infrared rays both within the rolling width of a steel plate and outside thereof by means of an infrared camera because the inclination and the intensity are different depending on the position. CONSTITUTION:The temperature of a steel plate after rolling is measured by a steel plate thermometer 23. In order to pick up only an infrared photographic signal from the steel plate based on the measured value, a filter is attached to each of infrared cameras 21, 22. The fixed camera 21 is moved and, a motor 27 is driven to move the camera 22. Both sides of the steel plate are photographed with a predetermined pitch by an image processor 25. Each pickup signal is processed by a gradation treatment, thereby to distinguish the position. The obtained image signals with gradation are connected to form a plane shape. When the image data is output to an image device 28, the maximum width and the rolling width are made clear from the displayed image. The maximum width and the rolling width are operated by tone device 25 and output to a host computer.

摘要： PURPOSE:To accurately measure steel plate breadth without any need of an illuminant as an auxiliary facility by detecting infrared radiated from a steel plate and calculating the breadth thereof from the detected value. CONSTITUTION:Infrared cameras 1 and 2 detect infrared radiated from a steel plate 3 with the breadthwise direction thereof taken as one dimension, and finds both ends of the steel plate 3. The cameras 1 and 2 are used as one- dimensional position sensors with horizontal scanning in a breadthwise direction. The surface temperature T of the steel plate 3 is measured with a radiation thermometer 4, and the wavelength of infrared corresponding to the temperature T is calculated and processed, thereby selecting the cut-on filter of the cameras 1 and 2 within a range optimum for the transmittance of the wavelength. This filter selection is automatically undertaken by a control device. When the steel plate 3 passes under the cameras 1 and 2, one-dimensional data of the steel plate 3 in a breadthwise direction is detected with the cameras 1 and 2. The end positions of the steel plate 3 are geometrically calculated from values detected with the two cameras 1 and 2, thereby calculating plate breadth W.

On the treatment of the load depending term, by learning the actually measured thickness of the preceding path with GM model and reflecting the rolled stock are corrected. Therefore, the accuracy of plate thickness is improved.

摘要： PROBLEM TO BE SOLVED: To properly determine the rolling sequence, and to enhance operation efficiency when rolling hot piece slab and/or cold piece slab in a rolling mill. SOLUTION: The rolling sequence of materials is determined by a data classification judgement processing partitioning the rolling sequence of the materials into only cold piece and only hot piece and the mix of the hot piece and the cold piece, by selecting a proper practice for each classification distinguished by the judgement processing, and by a processing optimizing the rolling sequence, which determines the rolling sequence by each evaluation function.

摘要： PURPOSE:To roll a steel plate including the shape of the steel plate so that its thickness is not below an objective thickness. CONSTITUTION:The fluctuation value of the allowable max. load so that the actual thickness of the steel plate at i-th pass is not below the lower limit value of the objective thickness of the steel plate is preliminarily determined with a process computer 20 and whether the load fluctuation value at the i-th pass is exceeded from the allowable max. load fluctuation value or not is discriminated with a AGC controller 17. The manipulated variable of an absolute value AGC is calculated with the AGC controller 17 by taking the allowable max. load fluctuation value as the load fluctuation value in the case of excess, and, on the other hand, taking the load fluctuation value as the upper limit value of the load fluctuation value in the case of not excess. The manipulated variable of the absolute value AGC calculated in the above-mentioned manner is outputted to a roll gap controller 19.
