摘要： 采用二冷区喷嘴冷态性能测试实验装置对攀钢360 mm×450 mm 方坯4流连铸机的9种扁平气水喷嘴特性进行了测试。测试表明，3/8PZ 10.6-120PG水喷嘴在喷嘴高度h 为115 mm 和140 mm, 喷射角度为115.6°和115.1°时，喷射有效长度d 分别为365 mm 和440 mm。HPZ4.8-90PG 气水喷嘴的喷射角度为 106.7°,当气压为0.15~0.30 MPa、水压0.30 MPa 时，h 为210 mm,d 为515～565 mm。

Abstract: The characteristics of 9 kinds of flat air-water nozzles for 4 strand 360 mm×450 mm billet concaster at Panzhihua Steel have been tested by using test device for measuring cold perormance of nozzles for secondary cooling. The test results showed that with nozzles level h was 115 mm and 140 mm and with jetting angle 115.6°and 115. 1°,the effective jetting range d for water nozzle 3/8PZ10.6- 120PG respectively was 365 mm and 440 mm. The jetting angle of air-water nozzle HPZ4.8-90PG was 106.7°,as air pressure was 0.15～0.30 MPa and water pressure was 0.30 MPa,the h was 210 mm and d was 515～565 mm
