With the sound of "Rumbling", the red steel plate moved quickly on the rollers, and after rolling, spray cooling, it turned into a black steel strip, and then curled into a steel coil.
There are more than 400 roller tables on the transmission track of more than 100 meters. During the hot rolling process, if a motor fails and the roller table stagnates, it will cause a large area of scratches on the surface of the steel strip and affect the product quality.
After using the '5G Industrial Internet' to upgrade key infrastructure equipment, the temperature, vibration, pressure, flow and other data collected by the equipment sensors will be transmitted to the cloud in real time, and then through artificial intelligence and big data analysis, real-time monitoring, diagnosis, disposal, etc.
Taking the 1780 hot tandem rolling production line as an example, after the application of "5G Industrial Internet", the motor current of each roller table will be collected in real time. Once an abnormality occurs, it will immediately alarm and accurately locate. In the past, after the scratches were found on the product, it was necessary to check the more than 400 rollers one by one. It took half an hour to an hour. Now the problem can be basically determined within 10 minutes. The maintenance efficiency has been improved, the downtime has been shortened, and the rate of scrap, defective and degraded products has dropped from about 7% to 3.8%, which saves production costs for enterprises.
In addition to fault maintenance, the application of "5G Industrial Internet" also realizes active maintenance of equipment.
Now through data analysis and scientific maintenance of equipment, the full life cycle management of equipment has been realized. On the 1780 hot tandem rolling production line, the number of emergency shutdowns and fault repairs after the transformation decreased by 20%, and the unit operation rate increased by 5%.
