A method of producing long products of steel by continuous casting in a continuous casting mold, wherein the steel products have the dimensions for the initial pass of a longitudinal rolling mill. Liquid steel is poured into a rotor-cooled continuous casting mold in which the steel solidifies partially with the formation of a ring-shaped strand shell having a round or oval shape in the cross-sectional area of the strand or a polygonal shape having more than four corners, and having a minimum circumference of 200 millimeters. The strand produced in this manner is reduced underneath the mold in its cross-sectional surface area until the strand fully solidifies by means of support members which act in a deforming manner on the strand, such that, while essentially maintaining its circumferential length, the strand is deformed into a shape meeting the requirements with a polygonal cross-section with at least four corners or an oval or round cross-section.
