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。
通過物理模擬對高壓底吹條件下鋼液流場進行研究，分析瞭壓力、底吹流量和底吹位置對鋼液流場的影響。研究錶明，噹壓力由常壓增加到1.5 MPa時，鋼液流場的渦鏇中心下降0.6 cm；偏心底吹比中心底吹更適閤鋼液的攪拌和混勻；底吹流量的增加有利于鋼液的混勻。
통과물리모의대고압저취조건하강액류장진행연구，분석료압력、저취류량화저취위치대강액류장적영향。연구표명，당압력유상압증가도1.5 MPa시，강액류장적와선중심하강0.6 cm；편심저취비중심저취경괄합강액적교반화혼균；저취류량적증가유리우강액적혼균。
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.
