Abstract

PURPOSE: To effectively prevent generation of the edge drop at a low cost, by continuously cooling a specified width of both edges of the steel strip undergoing the rolling work to temperature a specified degree lower than that of the middle zone in order to cause a deviation of the deformation resistance locally along the breadth of the strip.
CONSTITUTION: The nozzle headers 2 for spraying the cooling medium are installed above or above-and-below the runway of the steel strip 1; these nozzle headers 2 spray the cooling water or blow off the cooling atmosphere gas against both edges and their neighborhood of the steel strip 1. The cooling zones 1a are formed into a belt shape of a specified width, 100mm or so for example, from the edge of the strip, and are cooled continuously. The temperature detectors 3 are installed respectively for the cooling zones 1a and the uncooling zone 1b, and detected temperatures are inputted to the control unit 4. The control unit 4 controls the temperature difference between the cooling zone 1a and the uncooling zone 1b to 20W 50°C; hereby, a deviation is caused in the deformation resistance along the breadth of the steel strip 1, and the size of the strain is adjusted.
