Abstract

A steel strand having a thickness of 40 to 50 mm in cast in an oscillating mold for continuous casting at a speed of 2 to 20 m/min. The not yet completely solidified steel strand emerging from the mold is squeezed to such an extent that the inner walls of the already solidified strand shell are welded to one another. After the steel strand reduced in thickness in this way has been cooled to 1000.degree. to 1200.degree. C., the strip is rolled out in at least one pass with a 5 to 85% degree of deformation.
