Steel coil diameter calculation method

Abstract

The invention relates to a steel coil diameter calculation method; a seat lining plate is of an arc structure, a laser distance measuring sensor is mounted over the center position of the connecting line of the circle centers of two saddle lining plates, and the distance between the laser distance measuring sensor and the bottom face of a saddle is larger than the maximum steel coil diameter; thediameter of the steel coil is obtained through a formula R=(H1<2>+H2<2>-2*H1*H2-r<2>+D<2>) / 2(H1-H2+r) according to the distance H2 between the laser distance measuring sensor and the surface of the steel coil measured by the laser distance measuring sensor, wherein R is the radius of the steel coil, H1 is the vertical distance of the circle center connecting line of the laser ranging sensor and the saddle lining plates, H2 is the distance between the laser ranging sensor and the top of the steel coil and is the actual measurement value of the laser sensor, r is the radius of the saddle liningplates, and D is half of the distance of the circle center connecting line of the two saddle lining plates. The method can automatically measure the diameter of the steel coil, and improves the production efficiency.

Description

technical field [0001] This patent application belongs to the technical field of steel rolling automatic control, and more specifically relates to a method for calculating the diameter of a steel coil. Background technique [0002] Before coiling at the entrance of the strip steel production line, the diameter of the steel coil must be accurately measured, which is the data that must be used for automatic coiling. After the coil is unloaded at the exit, the diameter of the steel coil must also be measured for the information management of the coil warehouse. The traditional method is manual measurement, which has low measurement accuracy, is greatly affected by the quality of personnel, and is uncontrollable. It increases the labor intensity and labor cost of workers, and it is difficult to realize automatic winding, which restricts the improvement of production rhythm. Contents of the invention [0003] The technical problem to be solved by the present invention is to pro...
