In the continuous pickling and leveling production line of the cold-rolled sheet, the strip steel is leveled by a leveling machine after being subjected to a pickling and rinsing process, so that the sheet shape is improved. In the leveling process of the strip steel, the leveling liquid system sprays leveling liquid on the working roller and the supporting roller of the leveling machine so as to clean dirt on the surfaces of the strip steel and the roller, properly lubricate and reduce the temperature of the roller, and meanwhile, has an antirust function on the strip steel, so that the accurate concentration ratio of the leveling liquid has an important influence on the surface quality of the strip steel. The desalted water for the existing leveling liquid proportioning is connected to the leveling liquid mixing tank from the connecting point of a desalted water pipe network, the flow of the desalted water is suddenly high and suddenly low, the flow is very unstable, the leveling liquid stock solution is added to the mixing tank from the stock solution tank at a constant speed through a metering pump, and the desalted water and the stock solution are not simultaneously stopped when being added to the mixing tank, so that the concentration proportion of the leveling liquid is very unstable, and the stain is remained on the surface of strip steel after the concentration is abnormal, thereby influencing the product quality. The device of the utility model adds a desalted water centrifugal pump on the original desalted water tank, and specially adds desalted water to the leveling liquid mixing liquid tank to prepare leveling liquid with certain concentration, thereby solving the problem of abnormal concentration of the leveling liquid caused by flow mismatch in the leveling liquid proportioning process.

The leveling liquid system prepares leveling liquid with certain concentration, the two-way pipeline hand valve is kept in an open state, the electromagnetic valve and the metering pump are simultaneously opened when liquid preparation is started, desalted water and leveling liquid stock solution enter the mixed liquid tank, and after the stirring pump is started, the desalted water and the leveling liquid stock solution are fully mixed to obtain leveling liquid with certain concentration. Because the flow of the stock solution metering pump of the leveling liquid is constant and is influenced by the pressure of the desalted water pipeline of the external network, the flow of the desalted water added into the mixed liquid box is unstable, the flow added into the mixed liquid box is not proportioned according to a certain concentration, the concentration of the leveling liquid is suddenly increased or reduced, the use effect of the leveling liquid after mixing is influenced, and meanwhile, the surface quality of strip steel is also influenced.
