摘　　要：运用微机控制的多点压力测量扫描阀自动测示系统,对南京钢铁厂15t复吹转炉二次燃烧双流道氧枪的射流特性进行了冷态实测研究,获得了射流速度、压力分布规律及等速度剖面图,为设计和操作提供了重要依据。The multiple jet characteristics of a post combustion dual oxygen flow lance used for 15 t converter of Nanjing Iron and Steel Plant have been experimentally investigated by means of a multiple pressure scanivalve measurement system controlled by a microcomputer. The distributions of the jet velocity and the jet pressure, as well as jet isovelocity profiles at various dimensionless axial distances were Obtained. The experimental results have provided important bases for the design project and operation of t...
