How to roll the initial shape into the final shape by arranging the roller rolling device used in the reversible process

摘要

The present invention relates to a method for rolling an initial shape to a final shape by arranging a roller rolling device consisting of an edge rolling machine disposed between the first universal rolling mill on the inlet side, the second universal rolling mill on the exit side, and the two universal rolling mills. . The calibration device is arranged in front of the roller rolling group. The initial shape emerges from the continuous casting device, increasing the thickness at both ends of the web to a shape corresponding to the final shape to be created later. The volumetric size of the initial shape is to be rolled to match the web height, web thickness and / or flange width, and the initial shape is moved directly to the first universal rolling mill of the compact roller rolling group, resulting in the final shape with the specified dimensions. Of the final web height, web thickness and / or flange width to which the final roller can be rolled, or the cross section of the initial web shape and / or the increased thickness of the flange shape can be fully rolled in a compact roller rolling group. Rollers which extend in parallel with the roller rolling lines (W2) on the roller rolling groups (U1, SG, U2) before the initial shape is transferred to the first universal rolling mill of the compact roller rolling group in order to have a different dimension from the dimension. In the rolling line W1, the initial shape decreases and deforms due to the rolling in the roll. Therefore, the initial shape is pushed in the transverse direction and thus the compact roll. It is directly moved to the front of the rolling group (U1, SG, U2).
