In addition to the cost savings already provided by the energy saving measures and compact process of the mini mill, the costs are reduced even further by producing thin strips by the hot strip mill alone. The Endless Rolling Technology indispensable to the production of thin strips has been added to the mini mill to create a new hot strip rolling process. As part of this new design, the dynamic PC mill, which can control high crown and alter the cross angle with the line in operation, was introduced to enable flying gauge changes, ensuring an excellent strip shape. To ensure stable cutting and coiling during high-speed rolling, specialized exit equipment such as the high-speed strip shear and the Carrousel coiler have been developed and introduced.
