In order to prevent longitudinal surface cracks, a new type of air atomizing nozzle has been developed and applied to continuous casting machines as a secondary cooling system.
1) Air atomizing nozzle is superior to conventional spray nozzle in uniformity of slab surface temperature, in performance reliability and in wider applicability of cooling density.
2) Longitudinal surface cracks are remarkably reduced by this mist cooling method.
