Acid pickling device for galvanized steel strip production and using method of acid pickling device

Abstract

The invention discloses an acid pickling device for galvanized steel strip production and a using method of the acid pickling device, and relates to the technical field of galvanized steel strip production equipment. The acid pickling device comprises a base, an edge scraping mechanism, a collecting mechanism, an acid pickling box, a washing box and a purifying mechanism; the edge scraping mechanism for removing oxidized black skin comprises supporting rods, a supporting plate, a lower scraper, an upper scraper, an adjusting plate, an inverted-U-shaped frame plate and a hydraulic cylinder, thesupporting plate is arranged on the upper part of the base, and the lower surface of the supporting plate is fixedly connected with the upper surface of the base through the supporting rods. Before acid pickling, the oxidized black skin on the surface of a steel belt can be scraped off through the lower scraper and the upper scraper, the situation that the oxidized black skin on the surface of the steel belt influences acid pickling is avoided, the acid pickling effect is improved, consumption of acid liquor is reduced, then the production cost is reduced, in the using process, the distance between the lower scraper and the upper scraper can be adjusted, the device can be used for steel belts of different thicknesses conveniently, and applicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of production equipment for galvanized steel strips, in particular to a pickling device for production of galvanized steel strips and a method for using the same. Background technique [0002] Galvanized steel strip is processed by ordinary steel strip pickling, galvanizing, packaging and other processes. It is widely used because of its good anti-corrosion performance. It is mainly used to make metal products that are cold-worked and no longer galvanized. For example: metal products such as light steel keels, peach-shaped columns for guardrails, sinks, rolling doors, bridges, etc. [0003] During the processing of galvanized steel strip, pickling is required after annealing, but after the annealing is completed, raised oxide scales will form on the surface of the steel strip, which not only affects the pickling effect, but also increases the pickling effect. Liquid consumption, thereby increasing producti...

Problems solved by technology

[0003]During the processing of galvanized steel strip, the steel strip needs to be pickled after annealing, but after the annealing is completed, the surface of the steel strip will form raised black oxide scales , pickling not only affects the effect of pickling, but also increases the consumption of acid solution, thereby increasing the production cost
