STUDY ON ANGLE OF SPRAY COOLING WATER FOR 3/8 BD3 TYPE NOZZLE

Spraying mechanism of cooling water using 3/8" BD3 type nozzle in continuous casting machine is investigated. Theoretical formula of the effect of the nozzle structure on angle of spray cooling water is induced. The result obtainted from the formula agree well with practical ones. Based on discussing influence of the nozzle structure on angle of spray cooling water, the method to increase volume of the cooling water is proposed.
