Description

Degreasing system for ultrathin silicon steel strip Technical Field The application relates to the technical field of steel belt cleaning, in particular to a degreasing system for an ultrathin silicon steel belt. Background Degreasing and cleaning the strip refers to a process for removing pollutants such as grease, greasy dirt, lubricant, cutting fluid and the like on the surface of the strip through a physical or chemical method. This is a critical pretreatment step prior to strip processing (e.g., rolling, plating, welding, painting, etc.), directly affecting the quality and finish properties of subsequent processes. The traditional cleaning process is usually that after the ultrathin silicon steel strip is cleaned, a passivation groove is required to be arranged for avoiding rust of the steel strip, and passivation treatment is carried out on the steel strip, so that the whole volume is large, the occupied space is wider, and the factory building space is occupied greatly. Disclosure of utility model The application provides a degreasing system of an ultrathin silicon steel strip, which solves the problems of large whole volume and wide occupied space in the prior art, and adopts the following technical scheme: The degreasing system of the ultrathin silicon steel strip comprises a degreasing tank group and a distillation device, wherein the degreasing tank group is used for degreasing and cleaning the steel strip; the degreasing tank group comprises a main degreasing tank containing a cleaning medium and is used for cleaning and passivating the steel belt; The vacuumizing device is used for forming a vacuum environment in the distillation device and reducing the flash point of the cleaning medium; The distillation device is used for separating and removing grease and impurities in the degreasing tank set. Preferably, the degreasing tank group further comprises a pre-degreasing tank containing degreasing fluid, and the pre-degreasing tank is arranged at the front end of the main degreasing tank and is used for pre-cleaning the steel strip. Preferably, the distillation device comprises a distillation kettle, and a condensation recovery device and a slag discharging device which are connected with the distillation kettle, wherein the vacuumizing device is used for forming a vacuum environment in the distillation kettle. Preferably, the steel strip cleaning device further comprises a drying device, wherein the drying device is positioned at the tail end of the main degreasing tank and is used for drying the cleaned steel strip. Preferably, the automatic adding device is communicated with the main degreasing tank and is used for providing passivation solution into the main degreasing tank so as to ensure the concentration of the passivation solution. Still preferably, at least one set of squeeze rollers are further disposed in the main degreasing tank and the pre-degreasing tank, and the squeeze rollers are disposed at one end of the steel strip, from which the degreasing liquid is separated, and are used for removing the degreasing liquid on the surface of the steel strip. Further preferably, guide rollers are arranged in the main degreasing tank and the pre-degreasing tank, and the guide rollers are used for guiding the direction of the steel strip and increasing the contact time with the degreasing fluid. The beneficial effects of the application are as follows: According to the application, the same degreasing tank is adopted to degrease and clean the steel belt, passivation is carried out at the same time, and the distillation device is matched to distill and clean media in a vacuum environment, so that grease and impurities are separated and removed, and the passivation tank is not required to be independently arranged to passivate the steel belt, so that the whole occupied space can be greatly reduced, and the energy consumption and the waste liquid yield are reduced.
