Refining bottom argon-blown steel ladle

The utility model provides a refining bottom argon blowing steel ladle. More than two air bricks are arranged at the bottom of a ladle, each of the air bricks is provided with independent argon blowing pipelines and the air bricks can work in turn. Thus, the utility model realizes that the air bricks have the same service life with the steel ladle and avoids the defects caused by replacing the air bricks. Meanwhile, the utility model can ensure the high bottom blowing rate and make the ladle liner of the steel ladle eroded evenly, which enhances the service life of the steel ladle and reduces the consumption of refractory material.
