Description

Water retaining structure is cut in steel band production accident Technical Field The invention relates to the technical field of steel production, in particular to a water blocking structure for steel strip production accident shearing. Background The hot rolled steel plate is manufactured by a hot rolling process, and the production process mainly comprises pretreatment, initial rolling, intermediate rolling, finish rolling, cooling and curling. In the rough rolling process step, the steel plate output from the heating furnace enters the descaler and the rolling mill after being sheared by an accident, the descaler adopts high-pressure water for descaling, the water flow is large, and a large amount of water flows back into the heating furnace from the surface of a steel billet under the condition that the water retaining roller is not closed or the water retaining is abnormal, and the water retaining structure is used for blocking the descaling water of the descaler from flowing through the accident and shearing into the heating furnace. In the related art, an integral water baffle is hung between an accident shearing inlet and a heating furnace outlet through a chain, when the interval distance between the water baffle and the surface of a steel billet is too large, scale removal water can flow back into the heating furnace on the surface of the steel billet, so that the heating furnace and the steel billet are influenced by the outside and abnormal temperature drop is caused, the rolling effect of the steel plate is influenced, and when the interval distance between the water baffle and the surface of the steel billet is too small, the water baffle can generate hard friction with the steel billet during the deformation of the steel billet, and the conveying progress is influenced. In view of this, it is necessary to provide a water blocking structure for steel strip production accident shearing to solve the above-mentioned drawbacks. Disclosure of Invention The invention mainly aims to provide a steel strip production accident shearing water retaining structure, and aims to solve the problems that when the distance between the existing water retaining plate and a steel billet is large, the water retaining effect is poor, the surface of a descaling water-based steel billet flows back into a heating furnace, and when the distance between the water retaining plate and the steel billet is too small, the water retaining plate scratches the surface of the steel billet, and the product quality is affected.
