摘　　要：通过流体力学测试和冷态模拟实验，证明旋流喷头具有良好的特性。安钢和酒钢使用旋流喷头后，化渣效果好，起渣时间提前，冶炼过程平稳易控制，供氧时间缩短，耗氧量降低。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，认为可达到溅渣护炉的要求。Cold model experiments show that the swirl-flow lance-tip with multi nozzle have good characteristics of jet.When they are used in converters in Anyang and Jiuquan steel plants,good smelting results have been received:slag forming time is shortened;smelting process is stable and easy to avoid slag splashing;oxygen blowing time was cut down and oxygen consumption was reduced.According to analysis of jet characteristics and degree of slopping,the swirl-flow oxygen lance can satisfy the need of slag splashing for furnace protection and improve metallurgical results.
