Steel plate water cooling device

Abstract

The invention relates to the field of steel plate cooling, in particular to a steel plate water cooling device which comprises water cooling cylinders, a water inlet mechanism, a circulating mechanismand a cooling bin. The water inlet mechanism and the circulating mechanism are symmetrically arranged, a transfer plate is arranged between the water inlet mechanism and the circulating mechanism, the number of the water cooling cylinders is two, and the water cooling cylinders can be rotatably arranged on one side of the transfer plate; one of the two water cooling cylinders can always be opposite to the cooling bin, and the other of the two water cooling cylinders is located between the water inlet mechanism and the circulating mechanism, and the two ends of the corresponding water coolingcylinder can communicate with the water inlet mechanism and the circulating mechanism. An air flow cavity and a cooling cavity are arranged in the cooling bin, the cooling cavity is always opposite toone water cooling cylinder, a transmission structure is always opposite to the air flow cavity is arranged at one end of the corresponding water cooling cylinder, the water cooling cylinders are elastically connected with the transfer plate, a displacement mechanism is further arranged on the side of the transfer plate, the displacement mechanism is in transmission connection with the two water cooling cylinders and can force the two water cooling cylinders to move backwards, and a high-pressure spray head and a cooling spray head are arranged in the air flow cavity and the cooling bin correspondingly. The service life of the water cooling cylinders can be prolonged, and the heat exchange effect is uniform.

Thermal corrosion will lead to a significant decrease in the service life of the water-cooled roller, which will easily lead to damage and scrap of the water-cooled roller, which indirectly affects the heat transfer efficiency and quality
