Abstract: The invention relates to a rolling arrangement for rolling mills including means for continuously centering the rolls with respect to the product being rolled and for adjusting the pass defined by the rolls. A roll is mounted with its shaft on a cylindrical support which is displaceable within the frame of the rolling unit and comprises an outer threaded portion engaging with an annular threaded element whose rotation causes axial displacement of the support and of the shaft and the roll, thus allowing continuous centering thereof. Setting shims are provided between a cover of the structure supporting the roll and the frame of the rolling unit for adjustment of the pass defined by the rolls. Adjustment of the clearance of the two bearings supporting the roll shaft is obtainable by providing each of the outer rings of the bearings with the outer threaded portion and the threaded annular element and separately actuating the same.

Abstract: A cooling device for the wheel of a continuous casting machine, which has an annular header disposed internally to the casting ring of the wheel and a plurality of spray nozzles arranged on the header for spraying jets of cooling fluid onto the casting ring and comprises elements for separating the cooling fluid stream, distributed in the space between the inner peripheral surface of the casting ring and the header. The elements define with the peripheral surface and with the header a plurality of independant cooling sections each of which comprises at least one spray nozzle. The separator elements each have at least surfaces close to the peripheral surface of the casting ring and oriented so as to diverge the stream of cooling fluid into directions having opposite components transverse to the circumferential direction of flow of the cooling fluid on the peripheral surface of the casting ring during the rotation of the casting ring.
