还在1956年,即ARBED开始对试验性氧气转炉进行研究时,就已经知道进行喷吹氧气时夹入石灰粉的理论研究的困难。这是因为考虑到这一问题必须通过相应的生产试验才能解决。然而在喷枪上配置易更换的喷嘴即能解决这一问题。在这方面,实际试验时可能有许多不同的方案。据报导,LD—AC法能在相当短的时间内完成吹炼操作。 1957年创造了一种双流喷枪(图1),强烈的氧气—石灰粉混合流(二次氧气流)通过其中心喷嘴,而低压的环形氧气流则从
Also in 1956, when ARBED began its study of the experimental oxygen converter, the difficulty of theoretical studies on the entrapment of limestone powder during oxygen injection was already known. This is because taking into account this issue must pass the appropriate production test can be resolved. However, in the spray gun configuration easy to replace the nozzle that can solve this problem. In this regard, there may be many different options for actual testing. It is reported that the LD-AC method can be completed in a relatively short period of blowing operation. A double-flow gun (Figure 1) was created in 1957 with a strong oxygen-lime-dust mixed flow (secondary oxygen flow) through its central nozzle while a low-pressure annular oxygen flow from
