摘要

Invention patent: "cylinders for disposition on the inlet side or on the other side of the exit zone of an annealing furnace annealing contu00ecnuo and unit of use of cylinders of the tempering zone".It is provided a cylinder that can be prepared before and / or after a quenching zone of a continuous annealing furnace.The roller has a predetermined profile satisfying LK 242 0.7 x W ~ min ~; r = 0.1 x 10 ^ - 3 ^ up to 0.2 x 10 ^ - 3 ^; and tr 242 20Where LC represents the length (mm) of a flat portion in the center of the cylinder, W ~ min ~ represents the minimum width (mm) of a strip steel.R represents the slope of the tapered portions arranged on both sides of the cylinder, and tr represents the radius of curvature (m) of the boundary between the flat portion and the tapered portions.The cylinder can be used as a cylinder bottom and / or tensioning roller disposed on the side of the entry and / or on the output side of the zone of tempering.
