Leg for vacuum tank for refining molten steel |
摘要 |
A leg is fitted through a joint material into each of a pair of vertical openings on a bottom wall of a vacuum tank for refining molten steel, for protecting the vertical openings from molten steel. The abovementioned leg has an annular inner wall formed by piling up through a joint material a plurality of magnesia-chrome fired radial bricks in a plurality of horizontal annular rows arranged one on the other so as to form an inner bore for passing molten steel therethrough. The leg also has an annular outer wall formed by piling up through a joint material a plurality of magnesia-chrome fired radial bricks in a plurality of horizontal rows arranged one on the other so as to cover substantially the entire outer surface of the annular inner wall. The inner surface of the annular outer wall is in contact with the outer surface of the annular inner wall through a joint material.
