ABSTRACT:
For alleviating the problem in continuous casting of beam blanks that cracks are frequently formed at the fillet parts thereof not only is the mold cavity provided with a taper at its web part in the casting direction, but also the curvature 1/R of the curved fillet parts of the mold cavity are successively varied in accordance with the amount of free shrinkage of the solidified shell of the beam blank strand. Such variation in curvature is particularly significant in the casting of beam blanks having a web height that is close to 1 m.
