Abstract
The invention discloses a cooling section sealing plate device. The device comprises a sealing plate and an inclined plate welded to one side of the sealing plate. A square hole used for bearing a cooling frame is formed in the middle of the sealing plate, and the inclined plate is welded to the outer arc surface of the sealing plate and used for bearing water flow to flow out of the cooling area;the edge of the sealing plate and the edge of the square hole vertically extend upwards to form baffles used for preventing water from flowing out, wherein an oblique angle of 20-40 degrees is formedbetween the oblique plate and the sealing plate. The cooling section sealing plate device is simple in structure, convenient to use and capable of effectively reducing the influence of dripping waterquantity on the cooling section. Another purpose of the invention is to provide a method for reducing the influence of the dripping water amount on a cooling section by using the cooling section sealing plate device. The method is simple to operate, and the probability of quality problems of crack-sensitive steel is effectively reduced; meanwhile, the requirement on the precision of measuring equipment is reduced, and implementation on a continuous casting site is facilitated.
Description
Technical field [0001] The invention relates to the field of casting equipment, in particular to a cooling section sealing plate device and a method for reducing the influence of the amount of dripping water on the cooling section by using the cooling section sealing plate device. Background technique [0002] Due to the limitation of tooling conditions, the straight-arc continuous casting machine will drip the cooling water on the inner arc surface of the cast slab under the influence of gravity, causing uneven cooling of the inner and outer arcs, and internal cracks. The current methods mostly start from the water volume design, taking into account the collision loss of the cooling water volume, the spray volume of each nozzle and other factors to simulate the excess cooling water volume on the inner arc surface, and then adjust the water volume distribution ratio of the inner and outer arc surfaces to achieve a balance Cooling effect. However, in the actual production process...
