Cooling method for hydraulic cylinder of continuous casting cooling bed

The invention relates to the technical field of metallurgical continuous casting machine cooling bed hydraulic cylinder cooling, in particular to a continuous casting cooling bed hydraulic cylinder cooling method which comprises the steps that when the temperature of the outer surface of a hydraulic cylinder is larger than or equal to 55 DEG C, a dynamic adjusting valve for spraying water flow is controlled to be opened so as to cool the hydraulic cylinder; wherein the final water flow L2 of the cooling hydraulic cylinder is equal to L1 * K, L1 is the primary water distribution amount, and K is the temperature correlation coefficient of the casting blank. According to the method for cooling the hydraulic cylinder of the casting cooling bed, the requirements of energy conservation and water conservation can be met. 本发明涉及冶金连铸机冷床液压缸冷却技术领域，具体而言，涉及连铸冷床液压缸冷却方法，其包括：在液压缸的外表面的温度大于或等于55℃时，控制喷淋水流的动态调节阀开启，以给液压缸降温；其中，冷却液压缸的最终水流量L2＝L1×K，其中，L1为初级配水量，K为铸坯温度关联系数。本发明的铸冷床液压缸冷却方法，能够实现节能、节水的要求。
