Date Mar. 18, 1993.Steel is continuously cast by employing a mold and a casting track. The casting track has a metallurgical length wherein the steel is substantially liquidus at one end of the length and substantially solidified at the other end of the length. At a distance along the length, the area of the cross-section of the solidifying liquid steel is reduced while maintaining the length of the perimeter of the reduced cross-section. The distance is between about 10% and about 80% of the length from the one end to the other end.
