摘　　要：为进一步提高超低头铸机板坯质量,通过对目前连铸二冷区现有喷嘴的冷态特性进行测试分析,研究了喷嘴的特性及布置。从喷嘴选型、喷嘴布置及电动阀选型方面进行了优化设计,实现了"弱冷"配水的均匀冷却,使铸坯矫直温度横向、纵向都控制在980～1 020℃,提高了铸坯二次冷却的效果。To further improve the quality of extra-low head slab, investigation was made on the cold-state characteristics of the spray nozzles in the secondary cooling zone of the slab caster, and characteristics and distribution of spray nozzles were analyzed. The selection of types and distribution of nozzles and solenoids were optimized to realize uniformed cooling by moderate cooling water distribution to maintain the straightening temperature within approx. 980--1 020 ℃ in both longitudinal and lateral ways and improve the secondary cooling effect.
