Abstract
A new argon blowing mode with different flowrates for two purging bricks of a 70t steelmaking ladle has been explored in the present work. The mixing behaviour of the molten steel and the slag eye change were revealed by using a 1:3 scale factor of water model. The results show that, compared with the conventional mode with the same flowrate for each brick, the new mode effectively decreases the mixing time, and the total area of the slag eye changes slightly. The shortest mixing time was obtained by the case in which the brick locations are at 0.6 R with a 180° relative angle and a 22 L/min total flowrate.
