COMBINED ROLLER SUPPORT AND SPRAY COOLING SYSTEM FOR CONTINUOUS CASTING MOLDS

摘要

1185.002 COMBINED ROLLER SUPPORT AND SPRAY COOLING SYSTEM FOR CONTINUOUS CASTING MOLDS 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.
