Abstract

A process for making rolled stock directly from strands of continuously cast steel products in a working and forming installation, comprising two pairs of rolls which are respectively mounted in spaced relationship to each other along the path through which the strand travels. The distance between the rolls of each pair of rolls being adjusted so that the mass flow rate of said strand immediately upstream from the first pair of rolls being at least 0.5 percent larger than the mass flow rate of said strand immediately downstream from said first pair of rolls, while the mass flow rate immediately upstream and downstream from the second pair of rolls is substantially the same. The second pair of rolls squeezing the strand to such an extent that it effects a reduction in cross-sectional area in the strand of at least 10 percent.
