IPC: B21B45/02
Filed: 1984-01-28
Abstract: This method is applicable in metallurgy, the purpose being to produce rolled steel of an evenness which meets the requirements of the further processing industry. In addition, the production sequence in rolling mills is to be stabilised. A method is to be developed which eliminates the susceptibility of the hot rolled material to distortions on the cooling bed. This is achieved by accelerating or delaying the transformation, as compared with the normal sequence on the cooling bed, by means of metered pressurised water cooling as a function of the chemical composition of the steel and thus preventing an increase in length of the treated rolled material, due to the transformation, on the cooling bed.
