对于要不要保证射流动力相似,要根据所研究的问题而定。研究熔池运动对冶炼过程某些现象(如喷溅、冶炼时间等)的影响,一般说来不一定要保证射流的动力相似,如果研究喷入熔池后射流本身的某些特性和对其他现象的影响,则必需保证射流的相似条件。本文就前一个问题加以讨论。在研究熔池运动(即供氧制度)对冶炼过程的影响时,是否要保证射流动力相似,现在存在两种不同观点: 1.射流的动力相似是射流对熔池作用相似的先决条件,因此要保证射流动力相似。
Whether or not to guarantee that the jet power is similar depends on the problem under study. Studying the influence of puddle movement on some phenomena (such as splashing, smelting time) in the smelting process generally does not have to guarantee that the jet power is similar. If we study some characteristics of the jet itself after it is injected into the puddle, Phenomenon, you must ensure that the jet of similar conditions. This article discusses the previous question. There are two different points of view when studying the impact of bath movement (ie, the oxygen supply system) on the smelting process. 1. The similarity of jet forces is a prerequisite for the similar effect of jets on the bath. Therefore, To ensure similar jet power.
