A device and method for measuring the online size of a hot cylinder section, including: a data analysis module and a diameter measurement system connected thereto, a wall thickness measurement system and a rotational speed measurement system, wherein: two wall thickness measurement systems are respectively arranged on the cylinder At both ends of the joint, the rotational speed measurement system and the diameter measurement system are set on one side of the barrel joint. The data analysis module calculates the position change rate of the feature points on the barrel joint image continuously collected by the rotational speed measurement system to obtain the rotational speed of the barrel joint. According to the diameter measurement system The measured real-time temperature data and rotation angle data are calculated to obtain the diameter and top position of the cylinder section, and the wall thickness of the cylinder section is obtained by calculating the real-time total length of the optical path or the number of blocked optical paths measured by the wall thickness measurement system; the invention can measure the thermal state of the cylinder section in real time The size, small error, meets the measurement requirements, and can get the specific position of the measured diameter, providing accurate information for the refinement of rolling.
Description
technical field [0001] The invention relates to a measurement technology in the field of metal thermal processing, in particular to an online size measurement device and method for hot (600-1200° C.) barrel joints. Background technique [0002] Large-scale pressure vessels in petrochemical and other industries can be welded by multi-section cylindrical tube joints. Each section of the cylindrical barrel section needs to be forged or rolled to meet certain mechanical properties and dimensional requirements. In the process of rolling the barrel section in the barrel section rolling mill, in order to control the size of the barrel section and reduce the subsequent machining allowance, it is necessary to measure the diameter of the barrel section and the direction of the major and minor axes while the hot barrel section is continuously rotating. Since the surface temperature of the barrel section during the rolling process is as high as 800-1200°C, and it is in a high-temperatu...
