Device for shunting secondary cooling water in width direction of casting blank

A device for shunting secondary cooling water in the width direction of a casting blank comprises mist nozzles, two water baffles, two hydraulic cylinders with displacement sensors and control systems, wherein the mist nozzles are fixed to a sector-shaped section frame. The two hydraulic cylinders with the displacement sensors are connected to the two sides of the sector-shaped section frame in the width direction of the casting blank respectively and fixedly and located at the positions corresponding to the mist nozzles. The two water baffles are connected to the ends of piston rods of the two hydraulic cylinders with the displacement sensors respectively and located above the surface of the casting blank. When the piston rods of the two hydraulic cylinders with the displacement sensors are located at initial positions, the distance between the two water baffles is equal to the maximum width A of the casting blank, and the hydraulic cylinders with the displacement sensors are connected with the control systems. The device for shunting the secondary cooling water in the width direction of the casting blank has the advantages that redundant cooling water on the side portions of the casting blank can be dynamically shunted online according to the width section of the produced casting blank, the structure is simple, operation is convenient, control is accurate, actions are reliable, and the quality problems caused by supercooling of the side portions of the casting bank are solved.
