Comprehensive continuous production line for steel strip hot-dip galvanizing and multiple flat iron hot-dip galvanizing

Abstract

The invention discloses a comprehensive continuous production line of flat iron (multiple) hot-dip galvanizing and steel strip hot-dip galvanizing, including feeding equipment, annealing reduction furnace, closed tension regulator, zinc pot, lead-in machine, cooling and blunt Drying device and unloading equipment, flat iron hot-dip galvanizing and steel strip hot-dip galvanizing use the pickled steel strip as the base strip, and the entire production line passes the feeding according to the width specifications of the galvanized flat iron and steel strip. equipment, and then enter the annealing reduction furnace for annealing and reduction, and then enter the zinc pot for galvanizing. After the flat iron and steel strip come out of the zinc pot, there are zinc layers on all four sides. The flat iron and galvanized steel strip pass through the lead-in machine and pass through the cooling and passivation drying device respectively, and finally the unloading equipment tracks the cross-cutting and cuts horizontally according to the fixed length through computer control. The galvanized flat iron and galvanized The steel belt falls on the conveyor roller table. The invention has the advantages of merging two production lines and reducing the investment capital and risk of entrepreneurs.

Description

technical field [0001] The invention relates to the technical field of galvanizing equipment manufacturing, in particular to a comprehensive continuous production line for flat iron (multiple) hot-dip galvanizing and steel strip hot-dip galvanizing. Background technique [0002] Hot-dip galvanizing, also called hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. Hot-dip galvanizing immerses the rust-removed steel parts in a molten zinc solution at about 500 °C, so that a zinc layer is attached to the surface of the steel components, thereby achieving the purpose of anti-corrosion. Hot-dip galvanizing process: finished product pickling-water washing-adding auxiliary plating solution-drying-rack plating-cooling-chemical treatment-cleaning-polishing-hot-dip galvanizing completed. [0003] Due to the decline in the real economy in recent years, the cost of building a productio...
