Abstract

1. Method for the production of flat steel from continuous slabs of large or medium thickness or from thin continuously cast billets that are crimped and which then pass through a rough rolling line and through a finishing rolling line, characterized in that the scale is removed from the edges of the flat rolled before compression. . The method according to claim 1, characterized in that after passing through the draft rolling line and before passing the finishing rolling line from the edges of flat products, scale is re-removed. The method according to claim 1 or 2, characterized in that the scale from the edges of the flat product is removed using a high-pressure liquid, in particular at least one high-pressure water jet. The method according to claim 1, characterized in that at least one high-pressure water jet is supplied to flat products at an angle of 60 ° to 90 ° relative to the side surface of flat products, in particular at an angle of 75 °. 5. Rolling line for the production of flat steel products from continuously cast slabs of large or medium thickness or from thin continuously cast billets, including a first crimping device (1), a rough rolling line and a finishing rolling line, characterized in that it is located before the first crimping device (1) the first device (2) for removing scale from the edges of flat products. 6. The rolling line according to claim 5, characterized in that the second crimping device is provided in front of the finishing rolling line, and in front of it there is a second descaling device for removing scale from the edges of a flat rolled product. The rolling line according to claim 5, characterized in
