Steel coil width and temperature measuring device on walking beam and working method thereof

Abstract

The invention discloses a steel coil width and temperature measuring device on a walking beam and a working method of the steel coil width and temperature measuring device. The steel coil width and temperature measuring device is installed on one side of the walking beam, and comprises symmetrical spiral arms, telescopic arms, temperature sensors, ultrasonic sensors, position sensors and oil cylinders. The middle positions of the spiral arms are pivoted to one ends of the telescopic arms, the oil cylinders are installed at the other ends of the telescopic arms, the position sensors are installed on the spiral arms, the temperature sensors and the ultrasonic sensors are installed on the inner sides of the tail ends of the symmetrical spiral arms, and the temperature sensors, the ultrasonicsensors and the position sensors are connected with an external control system. The method comprises the following steps: receiving a new roll at a 3 # position, starting a measuring device, detectingby the measuring device, uploading a measuring result, resetting the measuring device, calculating the width, centering the width, judging the temperature and the like. The device achieves the full-automatic measurement of the width and temperature of an inlet steel coil, is safe and reliable, is precise in measurement, is simple in structure, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of hot-rolled leveling and trimming production lines, in particular to a steel coil width and temperature measuring device on a walking beam and a working method thereof. Background technique [0002] Walking beam is one of the most commonly used coil transport equipment in rolling mills. The width measurement and temperature measurement of the steel coil at the entrance of the hot rolling skin pass unit are all manually detected, and the width centering of the steel coil during transportation uses the incoming width data and laser distance measurement to determine the center position of the steel coil. The width measurement method is: first block the area equipment, use a tape measure to measure the width of the outer ring and inner ring of the steel coil, and record the actual data; the temperature measurement method is: first block the area equipment, use an infrared thermometer to align the steel coil T...

AI Technical Summary

Problems solved by technology

On the one hand, through manual measurement, the workload is large and the production efficiency is low. On the other hand, there is a risk of manual error, which affects the production quality. In addition, using the width data of the incoming material and the laser range finder to carry out the width alignment of the steel coil may Due to excessive measurement error, the center of gravity of the overflow coil deviates from the centerline of the width of the steel coil, resulting in a rollover accident
