Abstract: A combined roller support bar and spray cooling system for mounting at the open bottom of a vertically arranged molten metal continuous casting mold carries a horizontally axised roller which engages and guides the cast slab portion emerging from the mold. The bar is provided with a longitudinal passageway into which cooling water is flowed. The water flows out through numerous transverse passageways formed in the bar, which terminate in nozzle ends oriented to spray the water above and below the roller against the adjacent slab surface for cooling purposes. The spray water cools the interior of the support bar, as it flows through the passageways, to prevent heat caused warping and twisting and thereby maintain the pre-set, accurate orientation of the roller and nozzles.

The two parts are connected by a number of drawing anchors arranged at a distance from each other and at right angles to the roller paths. These anchors are detachable from one of the parts and are removable out of the connecting position with that part. The arc inner part carrying the arc inner roller path is pivotable, in the arc plane on the framework carrying the outer roller path, about a pivot axle arranged on the lower, run-out end of the framework.
