激波是超音速气流中液体属性的不连续面,气流通过激波时速度下降,温度和压强升高。氧气转炉炼钢的氧气是通过拉瓦尔管以超音速射流状态吹入转炉。在氧枪喷头设计和制定供氧制度时要减小激波损失。在转炉的某些特殊吹炼工艺中要把激波控制在适当范围内,以取得良好的冶金效果。 Shock waves are discontinuous surfaces of liquid properties in a supersonic gas stream, and the velocity of the gas stream as it passes through the shock wave decreases and the temperature and pressure increase. Oxygen converter Steelmaking oxygen is injected into the converter via a Laval tube in a supersonic jet. In the oxygen gun nozzle design and development of oxygen system to reduce the shock loss. In some special converter blowing process to control the shock within a reasonable range, in order to achieve good metallurgical results.
