Abstract

No. 3 continuous casting machine at No. 1 steel-making shop in Mizushima Works of Kawasaki Steel Corp. has capability of casting both large section blooms (300 × 400 mm, 400 × 560 mm) and beam blanks. It has been successfully operated since October, 1973. In continuous casting of beam blanks, various kinds of defects are liable to occur because of its complicated section. However, the adoption of suitable operating condition such as mold powder selection, cooling condition, and complete maintenance of machine have made it possible to roll almost all cast blanks without any surface conditioning. Casting speed has also been increased with good quality by preventing flange deformation of cast blanks.
