High rigidity, reliability and quick roll change capabilities are the key features of the state of the art mill stands, which are designed for producing bars, wire rod, angles, channels, and universal beams. The connection and disconnection of the spindles and all the fluid utilities are fully automatic and therefore the stands can be interchanged very quickly. Different versions including horizontal, vertical, convertible and drop-in-joker (which converts a horizontal to a vertical) are in operation, allowing rapid adaptation to the variety of the rolled products needed to fulfill stringent market demands. Line flexibility allows rolling with low temperature, high alloy, wide forming passes, etc.
Modern 2-high sliding stands are reversible and fully automatic. They represent an innovation solution for roughing and intermediate mills and constitute the latest stage of 3-high stand evolution.
Today’s mills can be used in a wide range of configurations in order to provide an ultimate selection of products from a single mill layout. It is possible to change from one unrelated product to another by simply pushing buttons and without the lengthy procedures needed for an old style mill change over. Convertible stands allow either horizontal or vertical positioning of the intermediate finishing trains in accordance with production requirements.
