摘要
通过物理模拟对高压底吹条件下钢液流场进行研究,分析了压力、底吹流量和底吹位置对钢液流场的影响。研究表明,当压力由常压增加到1.5 MPa时,钢液流场的涡旋中心下降0.6 cm;偏心底吹比中心底吹更适合钢液的搅拌和混匀;底吹流量的增加有利于钢液的混匀。
Molten steel flow field under the condition of bottom blowing and high pressure are studied by physical simulation, the influences of the pressure, bottom blowing flux and bottom blowing position on steel flow field were analyzed. Research results show that when the pressure increased from normal atmospheric pressure to 1.5 MPa, the vortex center of the liquid phase declines 0.6 cm. Eccentric bottom blowing is more advantageous to liquid mixing and stirring than center bottom blowing. With the increase of bottom blowing flow rate, liquid phase stirring effect is better.
