The invention relates to a cold-rolled galvanizing line passivation liquid dosing system and its operation method. The liquid supply sealing tank is placed above two working liquid tanks, the top of the liquid supply sealing tank is provided with a liquid filling cover, and the liquid supply sealing tank The bottom of the liquid outlet is connected to the upper end of the liquid supply pipe, the lower end of the liquid supply pipe is connected to the upper end of the corresponding side limit tube through a quick change joint, and the lower end of the limit tube extends into the corresponding working fluid tank; the working fluid tank There is a pick-up roller and a coating roller above the top of the feed roller, and the lower part of the pick-up roller is immersed in the passivation liquid in the working fluid tank. Contact; the working liquid tank is connected to the liquid receiving tank through the return pipe, and the return liquid outlet at the bottom of the liquid contact tank is connected to the liquid supply pipe through the return liquid supply pipe; the return liquid supply pipe is provided with a return liquid pump. The system of the invention has simple structure, strong prevention and error correction ability, greatly reduces equipment failure rate, lowers maintenance cost, and avoids passivation liquid leakage and passivation spot defects.
Description
technical field [0001] The invention relates to the technical field of cold-rolled galvanized sheet production, in particular to a cold-rolled galvanized line passivation solution adding system and an operation method thereof. Background technique [0002] In most cold-rolled galvanizing lines, passivation and oiling coexist to prevent oxidation of galvanized strips during transportation and short-term storage. According to the application occasions, transportation and storage conditions of galvanized sheets, the galvanized sheets can be passivated or oiled respectively, or the double treatment of first passivated and then oiled can be carried out to meet the different requirements of users. [0003] At present, most of the passivation treatment equipment configured online is a four-roller roller coater, which coats the upper and lower surfaces of the strip with passivation solution through 2 coating rollers and 2 lifting rollers. However, conventionally used passivation tr...
