Molten steel refinement device

The invention discloses a molten steel refinement device. The molten steel refinement device comprises a refinement container, in which is disposed molten steel; a separation wall, which is used to divide the upper space of the refinement container into two sides in the state of the two sides of the separation wall immersed in the molten steel; and bottom blowing parts, which are respectively disposed on the lower part positions of the space in the two sides of the refinement container separated by the separation wall, and is used to provide gas for stirring the molten steel. 本发明公开种钢水精炼设备。根据本发明的实施例的钢水精炼设备包括：精炼容器，在其内部容纳钢水；分隔壁，在其下侧沉浸在钢水中的状态下，将所述精炼容器的上部空间划分为两侧；及底吹部，分别设置在由所述分隔壁划分的所述精炼容器的两侧空间下部位置，以供给用于搅拌钢水的气体。
