Device and method for completing steel coil width centering on walking beam

Abstract

The invention discloses a device for completing steel coil width centering on walking beam. The device comprises a large steel coil, a small steel coil, a width centering trolley, a fixed saddle, a cantilever support, a position sensor, an ultrasonic sensor and a temperature sensor, wherein the small steel coil is arranged at the bottom of the inner side of the large steel coil, the width centering trolley is arranged at the bottom of the large steel coil and the bottom of the small steel coil, the walking beam is fixedly arranged at the bottom of a sliding rail, the cantilever support is arranged at the front end of the fixed saddle, an ultrasonic sensor is arranged at the inner side end of the top of the cantilever support, the temperature sensor is arranged at the front end of the top of the cantilever support, a rotating shaft is arranged in the middle of the bottom of the cantilever support, an oil cylinder is connected to the front end of the rotating shaft, and the position sensor is arranged at the front end of the cantilever support. Width centering of the steel coil at an inlet is achieved according to a gravity center position of the steel coil, coil upending accidents are avoided, the automatic production efficiency is improved, the effect of personnel simplification is achieved, full-automatic operation is achieved, safety and reliability are achieved, measurement is accurate, and maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of flattening and trimming production lines in a hot-rolling finishing area, in particular to a device and a method for centering steel coil widths on a walking beam. Background technique [0002] The coil width centering at the entrance of the traditional hot rolling finishing line is completed at the first position of the walking beam, based on the data detected by the laser rangefinder, and then the coil width is adjusted by the coil transport trolley. Its control principle is: the steel coil transport trolley needs to transport the steel coil from the 3# saddle position to the 4# saddle position, and complete the width alignment on the 4# saddle position, and the laser range finder is installed on the 3# Between the 4# saddle (perpendicular to the traveling route of the trolley), when the steel coil passes the laser range finder, the PLC can accurately calculate the width of the steel coil according to t...

Problems solved by technology

According to on-site production experience, when the overflow exceeds 200mm, although the geometric center of the steel coil is still on the center line of the walking beam, its center of gravity has deviated from the movable beam of the walking beam, resulting in an accident when the walking beam starts to roll. rollover accident
