Title:

ENERGY-SAVING DEVICE FOR ROLLING PLANT

Document Type and Number:

WIPO Patent Application WO/2013/030945

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a control device for a rolling plant, the control device capable of reducing the water injection amount by injecting cooling water at a timing at which the cooling efficiency is high when a rolled stock is cooled to thereby reduce energy consumption. The present invention is provided with a plurality of rolling stands (24) which are disposed in tandem in a rolling line, and roll a rolled stock (12) produced from a metallic material and conveyed on the rolling line, and inter-stand cooling units (50) which are each provided between the plurality of rolling stands (24) and inject cooling water to the rolled stock being conveyed. The water injection amount from an inter-stand cooling unit (50) located closer to the upstream side of the rolling line among the inter-stand cooling units (50) is set larger, and the water injection amount from an inter-stand cooling unit (50) located closer to the downstream side is set smaller.
