Patent ID: 8429943

Claim:
A process for hot rolling slabs in a hot strip mill or in Steckel mills, comprising the steps of: applying lateral contact pressure against the slabs via lateral guides upon occurrence of skewed running of the slabs, the lateral guides extending in a rolling direction of the slabs; systematically influencing geometry of a near-net strip during rolling of the slabs into the near-net strip in at least one roughing stand by carrying out in combination 1) a roll alignment for dynamic adjustment in a horizontal stand that is based on a continuously measured differential rolling force (ΔF LC ), and 2) a fast and powerful position and force control of the lateral guides which are installed upstream and downstream of the roughing stand, where piston position and piston pressure of piston-cylinder units that adjust the lateral guides are used for controlling the lateral guides, and adjusting a distance between the lateral guides so that the distance conically increases at front ends of the guides, so that a slab affected with cambering or wedging is systematically shaped into a straight and wedge-free near-net strip in at least one pass in a reversing or continuous operation.
