STUDY ON ANGLE OF'SPRAY COOLING WATER FOR 3/8 BD3 TYPE NOZZLE Zhang Keqiang Abstract Spraying mechanism of cooling water using 3/84 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. 0参 考 文 献 〔 〕 邯 钢小方坯连铸机二冷喷嘴冷态特性研究 连铸工艺鉴定 会议 资料之九 勺室 、 ，’
