The invention relates to a spraying device for a damped moderately thick plate. The spraying device comprises a spraying water tank and a spraying header located at the top of the spraying water tank, further comprises a damping sleeve and at least one damping plate which are arranged in the spraying water tank, and a plurality of damping holes are uniformly formed in the damping sleeve and the damping plate; all damping plates are uniformly arranged in the spraying water tank in parallel from bottom to top, and can be used for dividing the space in the spraying water tank into a plurality of layers; the at least one damping sleeve is arranged in a down-most space and is connected with an external water supply pipe. The spraying device provided by the invention has the beneficial effects that the pressure of cooling water in the spraying tank is stabilized by adopting the spraying device in a multi-damping structure, so as to equalize the flow of water sprayed by the header, improve the cooling uniformity of a steel plate, and improve the quality of the steel plate.
Description
Technical field [0001] The invention relates to the field of controlled cooling of hot-rolled medium and heavy plates, in particular to a spray device suitable for controlled cooling of hot-rolled medium and heavy plates. Background technique [0002] In the plate engineering, controlling the cooling system directly affects the quality of the steel plate produced. Controlling the cooling water is very sensitive to water pressure. Only when the cooling water pressure in the spray water tank is stable, the amount of spray water will be relatively stable, so that the length and width of the cooled steel plate will be evenly cooled. Therefore, the design structure of the spray device is very important. [0003] At present, many spray devices do not have a damping structure design or only have one-stage damping, so that the water flow from the spray header along the width of the steel plate is not very stable, which affects the cooling effect of the steel plate and the cooling uniformi...
