METHOD AND INSTALLATION FOR PRODUCTION OF HOT-ROLLED STRIP

摘要

A method for continuous production of hot-rolled strip is intended to be used by metallurgy industry enterprises and comprises continuous casting of a thin slab which is accumulated and rolled into strip in limited sections and in several runs and then returned to the accumulation zone, cut and coiled. The slab and the returned section are accumulated, simultaneously with heating, by their joint reeling into an intermediate coil which, in the course of reeling and unreeling of the sections of slab and of rolled strip on it and therefrom, is moved along the accumulation zone. An installation for implementation of the method comprises a roller furnace (3) and a accumulator consisting of a carriage (13) mounted outside of the roller furnace movably along the latter and of a device (14) intended for forming the intermediate coil (15) of the slab and of the section of strip to be returned and mounted on the carriage (13) inside the heating furnace (3), thus ensuring the movement of the intermediate coil (15) above the rollers (11) of the furnace during the process of its reeling and unreeling.
