摘要： PURPOSE:To enable highly accurate measurement and fast computation of a distortion shape by removing errors due to playing of a plate material and errors attributed to a long-term error of a displacement meter in the measurement of the distortion shape. CONSTITUTION:Displacements y1i and y2i are detected with displacement meters 1 and 2. An arithmetic device 12 determines a displacement difference dyi from the displacements y1i and y2i detected to obtain an integration waveform y3 of an integration computation (first) over the overall length in the longitudinal direction of a steel plate 3 from the displacement difference dyi. The first integration waveform y3 is converted to a second integration waveform y3' with a mean thereof zero. A sum of products function S is determined between a linear function which becomes zero at the center of a integration computation range and represents +1 and -1 at both ends thereof and a second integration waveform y3' converted. An inclination function G which is determined by the sum of products S is subtracted from the first integration waveform y3 to obtain a distortion shaped of the steel plate from a subtracted value.

摘要： PURPOSE:To make it possible to measure a thickness with high accuracy, by detecting the elongation of a housing to which a radiation source and a radiation intensity detector are fixed in opposed relationship and correcting the output of a radiation intensity detection value based on the detection value. CONSTITUTION:When the thickness of a rolling material 14 is measured from the transmission quantity of radiation in such a state that a radiation source 10 and a radiation intensity detector 16 are mounted to the housing of a rolling machine 60, the elongation of the housing of the rolling machine 60 generated at the time of rolling is detected. The elongation quantity of the housing may be calculated according to a gauge meter system, for example, by measuring rolling repulsive force by load cells 54A, 54B. This elongation quantity is inputted to a second correction apparatus 56 and, according to the correction value, the detection value (t) from the radiation intensity detector 16 is corrected. By this method, the effect of the variation in distance between the radiation source 10 and the detector 16 can be removed and a rolling thickness can be accurately measured.

摘要： PURPOSE:To make it possible to accurately obtain a measured value, by providing a detector for detecting radiation intensity between frame pieces through a high frequency attenuation type buffer apparatus. CONSTITUTION:A detector 12 is held by a buffer apparatus 13. The buffer apparatus 13 consists of vibration proof rubber 13a, a damper 13b and a spring 13c and vibration of several 100Hz is absorbed by the vibration proof rubber 13a and the vibration of a rolling machine is suppressed within a short time by the damper 13b and the spring 13c has function extremely reducing the transmission of vibration impact. Because the buffer apparatus 13 fixes the detector 12 at three points or more, said apparatus 13 can prevent not only the absorption of vibration impact in vertical and horizontal directions generated in the rolling machine but also the rotary motion of a radiation transmission type thickness meter. Therefore, even if the radiation transmission type thickness meter is arranged to the rolling machine, the accurate measurement of the thickness of a plate can be performed without receiving the effect due to vibration and impact.

摘要： PROBLEM TO BE SOLVED: To provide an end position detection apparatus that can accurately detect an end position even if the change in the end temperature is large, at the same time, can be maintained easily, and has less restrictions in the installation location. SOLUTION: In the end detection method of a material to be carried, a self-luminance from the end of a material to be carried is received by the image sensor of a camera that is arranged at the upper section of a transport line, and the position of the end is detected based on the quantity of received light of the self-luminance thus obtained. When the quantity of received light of self-luminance that is received by the image sensor is in shortage, light from a light source that is arranged at the upper section is applied to the end, reflection light obtained by reflection from the end is received by an image sensor in addition to the self-luminance and the quantity of received light of the reflection light obtained by reception is added to the quantity of received light of the self-luminance to detect the position of the end.
