The results showed that the range of target finishing temperature can be provided and kept on in an energy - saving manner with lower frequency of spray nozzle opening if opening reversely but closing forwardly the cooling valve for inter - stand spray during water cooling 对两种截然不同的机架间喷水冷却阀门开启逻辑做了计算分析,结果表明,逆向开启机架间喷水冷却阀门,顺向关闭阀门,能以较少的喷嘴开启数达到终轧温度目标范围,并且可以节约能耗。
