摘　　要：通过利用风口测量枪进行的微波反射测量方法讨论了大煤粉喷吹量条件下高炉风口回旋区的形成。由于喷吹煤粉的燃烧,作为焦炭进入风口回旋区动力的焦炭流量减小,定义为微波反射最大位置的风口回旋区深度缩小。该项技术可以探测风口回旋区的短时塌缩现象,并证实风口回旋区在煤粉喷吹中的稳定性与全焦操作中的不同。总结了风口回旋区的形成对高产中使高炉发生功能紊乱的布料不稳定状况的影响。The blast furnace raceway formation under the intensive coal injection by measurement of micro wave reflection gunned through a tuyere is discussed. As the flow rate of coke as the momentum of coke into raceway decreases by combustion of coal injected into tuyeres, the depth of raceway defined as the maximum position of micro wave reflection is easy to contract. It is expected that this new technology could detect the raceway collapse phenomena in short time and that the stability of raceway in coal injection is different from that in all coke operation. Finally the paper ends by summarizing the effect of raceway formation on unsteady phenomena forcing functional disorder on blast furnace performance of burden distribution for high productivity performance.
