攀钢板坯连铸机二冷区喷嘴特性测试
DETERMINATION OF SPRAY NOZZLE CHARACTERISTICS IN SECONDARY COOLING ZONE OF PANGANG SLAB CONTINUOUS CASTER
-
摘要: 对连铸二冷区喷嘴的冷态特性进行了研究。测定了不同喷水条件下喷嘴的压力—流量关系，喷水密度分布以及喷射角和喷雾粒度分布。分析了国内外喷嘴的特性曲线，为国内厂家生产喷嘴提供了更为合理的参数。Abstract: The cold state characteristics of spray nozzles in secondary cooling zone of slab continuous caster were investigated.The relation between pressure and water flow rate, distribution of spray water flux, and distribution of spray angle and water droplet diameter were measured under different spray water conditions.The characteristic curves of spray nozzles made at home and abroad were analyzed.The more rational parameters are provided for domestic plants to produce spray nozzle.
