The present invention relates to a treatment apparatus for forming a path through which molten steel moves to move the molten steel, comprising: a plurality of refractory bricks arranged to surround the path and constructed in one direction; an iron bar installed to surround an outer circumference of the refractory bricks; and a support unit installed between the refractory bricks and the iron bar, having lower thermal conductivity than the refractory bricks, and having a portion protruding in a direction intersecting with one direction to support the refractory bricks to be inserted into the refractory bricks. Therefore, the refractory bricks are stably supported to stably treat the molten steel. 본 발명은 용강을 이동시키도록 용강이 이동하는 경로를 형성하는 처리장치로서, 상기 경로를 감싸도록 배치되고, 일방향으로 축조되는 복수개의 내화벽돌; 상기 복수개의 내화벽돌의 외측 둘레를 감싸도록 설치되는 철피; 및 상기 내화벽돌과 상기 철피 사이에 설치되고, 상기 내화벽돌보다 열전도율이 낮으며, 상기 내화벽돌을 지지해주도록 일부가 일방향과 교차하는 방향으로 돌출되어 상기 내화벽돌에 삽입되는 지지부;를 포함하고, 내화벽돌을 안정적으로 지지해주어 용강을 안정적으로 처리할 수 있다.
