Abstract :
In order to improve productivity of the Large Shape Mill at Kashima Steel Works, an online profile measuring system of hot steel shape with a laser has been developed. The system can automatically measure four shapes which are produced in 288 sizes in total. The system can measure the shape which is on the rolling table. The temperature of the measured shape is approximately 800 degrees C. Five methods are adopted to greatly improve accuracy. After adopting the automatic measuring system the productivity of the Large Shape Mill has increased 1.5% compared with manual measurements.<>
