摘　　要：通过流体力学测试和冷态模拟实验，证明旋流铸铜喷头（三孔或四孔）具有良好的特性。安钢和酒钢使用旋流喷头后，化渣效果好，起渣时间提前１～２ｍｉｎ，冶炼过程平稳易控制，不易发生喷溅，供氧时间缩短近３ｍｉｎ，耗氧量降低５．７５ｍ３／ｔ。从冲击动力、喷溅量和流股特性等方面分析了旋流喷头的优点，可以满足溅渣护炉的要求，并能够提高溅渣的均匀性和效果。Cold model experiments show that the swirl flow oxygen lance with multi nozzles has good characteristics of jet When they are used in converters at Anyang and Jiuquan Steel Plants,good smelting results have been received,such as slag forming time moves up 1～2 min,smelting process is stable and easy to avoid slag splashing,oxygen blowing time is cut down by 3 min,oxygen consumption is reduced by 5 75 m 3/t etc According to analysis of jet characteristics and degree of slopping,the swirl flow oxygen lance can meet the need of slag splashing technology and improve metallurgical results
