Rolling plant saving device
2011
Object of the present invention is to provide a control device as a rolling device: during the cooling roll by the time point higher cooling efficiency of the cooling water can be reduced perfusion water injection, and achieve a reduction in power consumption. Comprising: a plurality of rolling stands (24), the plurality of rolling stands (24) arranged in a tandem rolling line, the metal material in the rolling line of the rolled material conveyed (12 ) rolling; and interstand cooling means (50), the inter-stand cooling means (50) are provided between the plurality of rolling stands (24), and transmitted to the roll cooling water is poured. The interstand cooling means (50), the water amount is set larger from the interstand cooling device is located upstream side of said rolling line (50), located downstream from the cooling means between the rack ( 50 less) of water injection.
