fl ow. The rolling operation has come to be known as rolling-slitting. When used on section mills and rod mills, methods based on rolling-slitting offer several advantages compared to conventional methods: 1) more effi cient use of the capacity of the heating furnaces; 2) faster entry of the semifi nished product into the rolling mill;
In the context of rolling mills, Industry 4.0 integration allows for seamless connectivity and data exchange between different manufacturing systems. The advantages of Industry 4.0 integration are far-reaching. Real-time monitoring and communication between various components of the rolling mill facilitate data-driven decision-making.
