COOLANT NOZZLE APPARATUS FOR TWIN-BELT CASTING MACHINE

摘要

COOLANT NOZZLE APPARATUS FOR TWIN-BELT CASTING MACHINE Coolant nozzle apparatus for use in twin belt casting machines wherein the casting region is defined between opposed portions of a pair of revolving endless flexible casting belts and wherein the belts travel partially around respective nip rolls positioned upstream from the casting region with said nip rolls having deep circumferential grooves. The apparatus comprises curved coolant feed tubes which are curved to nest within the deep grooves and having nozzles at their ends with fingernail-like extenders attached to the ends of the respective tubes on the convex side of said tubes, said extenders projecting beyond the discharge ends of the respective associated nozzles in position to intercept and spread out the coolant stream issuing from the nozzle, and the fingernail-like extenders tapering to a sharp straight edge toward which the spread out stream of coolant moves.
