Abstract

The invention relates to a laminar cooling edge shielding device which comprises an upper laminar manifold device, the two ends of the upper laminar manifold device are fixedly connected with a water tank supporting beam, the two sides of the water tank supporting beam are provided with a transmission side water collecting tank and a work side water collecting tank correspondingly, the water tank supporting beam comprises an upper fixing beam and a lower fixing beam, the upper fixing beam and the lower fixing beam are connected through a connection support, the connection support is provided with a water tank hydraulic cylinder, the transmission side water collecting tank and the work side water collecting tank are pushed by respective water tank hydraulic cylinders to slide on the water tank supporting beam, the transmission side water collecting tank and the work side water collecting tank are connected through a corrugated telescopic water pipe, and the bottom of the transmission side water collecting tank is provided with a drainage hose. The spraying area of cooling water in the width direction of strip steel is adjusted, the phenomenon that cooling distribution of a laminar cooling system in the width direction of strip steel is solved, strip steel edge temperature drop is reduced, and the strip steel cross section temperature difference is reduced.

Description

technical field [0001] The invention relates to steel rolling equipment, in particular to a laminar flow cooling edge shielding device and a control method. Background technique [0002] Laminar cooling is an important link in the temperature control of hot-rolled strip production. Its main disadvantages are: the laminar cooling control system can only adjust the temperature in the rolling direction of the strip, but not in the width direction of the strip. This will cause uneven temperature distribution along the width direction of the strip, and the residual stress generated after cooling will affect the final flatness of the strip, resulting in strips with "edge wave" defects. This effect is especially pronounced in the laminar cooling zone. The thinner the strip thickness, the greater the possibility of producing a strip with "edge wave" defects. In addition, due to the different cooling rates, the properties of the middle and edge of the strip are also very different. ...
