The invention provides a device and method for cooling an intermediate rolled blank of a hot rolled strip. The device comprises an upper collecting pipe arranged above roller beds and a lower collecting pipe arranged between the roller beds, wherein the upper collecting pipe and the lower collecting pipe are both provided with nozzles and opening and closing control valves and are connected with a workshop circulating water system through collecting pipe water supply pipelines; and the collecting pipe water supply pipelines are provided with flow control valves. The opening and closing control valves and the flow control valves are controlled by a programmable controller. A plurality of groups of cooling collecting pipes which can be independently controlled to open and close and has smaller flow are arranged between every two roller beds, the intermediate blank is cooled by adopting water jet, and the cooling speed is correspondingly dynamically controlled according to the transmission speed of the intermediate blank. The invention has the advantages of relatively simple structure of the device, low requirement for water quality, good flow stability and high production efficiency, and is convenient to maintain and free of limit of speed raising of a roughing mill and deceleration of throwing steel; rolling mill cooling water is adopted and a single water supply and drainage system is not needed; and grains of the intermediate blank are remarkably refined, and the mechanical property of a steel plate is improved.
