当转炉吹炼不同成分的生铁时,巨大潜力存在于完善现有的和拟定出新的最佳吹氧制度。此时,热交换和质交换过程的流体动力学和气体动力学具有决定性的意义。带拉伐尔喷孔的多孔喷头,能使气流分散成超声速流出,因而加快了传热和传质的过程。这种流股的固有特点,是流场成复杂冲击波结构,产生激波和负压区,而且可以靠改变喷 When converting converter pig iron of different composition, the great potential exists in perfecting existing and drafting a new optimal oxygen blowing system. At this point, the hydrodynamics and gas dynamics of the heat exchange and mass exchange processes are of decisive significance. Laval nozzle with a porous nozzle, the air can be dispersed into supersonic outflow, thus speeding up the heat transfer and mass transfer process. The inherent characteristics of this stream is the flow field into a complex shock wave structure, resulting in shock and negative pressure zone, but also by changing the spray
