Description

TECHNICAL FIELD

[0001] The utility model relates to steel band production technical field, concretely relates to a kind of cleaning device for steel band pickling. BACKGROUND

[0002] Pickling has multiple effects and necessity in steel band production, and can remove the oxide layer and pollutants on the surface of the steel band. During high-temperature processing such as hot rolling and welding, an oxide layer and welding slag are formed on the surface of the steel band, which can affect the appearance and performance of the material. Through pickling treatment, an acidic solution such as nitric acid, sulfuric acid or hydrochloric acid can be used to chemically react with the pollutants on the surface of the metal, causing them to dissolve or peel off, thereby removing these impurities.

[0003] After pickling, the steel band is placed in clean water for cleaning to remove the acid and other corrosive substances left on its surface. Some impurities and water droplets may be attached to the steel band when it is fished out of the clean water, and it also needs to be cleaned, otherwise it may cause the steel band to rust again.

[0004] Chinese patent authorization announcement No. CN214276318U provides a squeezing device for steel band pickling production line. When the steel band is pulled by the transmission roller one and the transmission roller two, the lower brush roller can brush off most of the acid on the lower surface of the steel band. At this time, the lower protective cover prevents acid splashing, and the acid splashed into the lower protective cover can be drained back into the pickling tank through the liquid leakage pipe. The upper brush roller can brush off most of the acid on the upper surface of the steel band. At this time, the upper protective cover prevents acid splashing, which can improve the service life of the squeezing roller.

[0005] However, the following defects exist in the specific implementation process: the single squeezing method has poor cleaning effect on the residual acid and water droplets on the surface of the steel band, cannot ensure that the steel band is fully dried, and cannot avoid the rusting of the steel band again. At the same time, the device cannot wind the cleaned steel band.

[0006] Therefore, the utility model designs a kind of cleaning device for steel band pickling to solve the above problems. UTILITY MODEL CONTENTS
