Strip hot-dip galvanizing and steel strip hot-dip galvanizing comprehensive continuous production line

Abstract

The invention discloses a strip hot-dip galvanizing and steel strip hot-dip galvanizing comprehensive continuous production line. The production line comprises feeding equipment, an annealing reduction furnace, a closed type tension adjusting machine, a zinc pot, an upper machine, a cooling and passivation drying device and a discharging device, the flat-iron hot-dip galvanizing and the steel-strip hot-dip galvanizing are carried out by taking an acid-washed steel strip as a base band, and then enters an annealing reduction furnace for annealing reduction according to the width specifications of the galvanized flat iron and the steel strip on the whole production line, and then enters a zinc pot to be coated with zinc, the flat iron and the steel strip are all provided with a zinc layer on the four sides, the zinc-plated flat iron is opposite to the finished product discharging direction of the zinc-plated steel strip, the galvanized flat iron and the galvanized steel strip are respectively subjected to cooling and passivation drying by virtue of an upper machine, the transverse shear is controlled by the blanking equipment to be controlled to be transversely cut off by a computer according to the length of the fixed ruler, and the galvanized flat iron and the galvanized steel strip which are transversely cut off fall on a conveying roller way. The method disclosed has the advantages that two production lines are combined, and the investment and the risk of the building are reduced.

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...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a comprehensive continuous production line for flat iron (multiple) hot-dip galvanizing and steel strip hot-dip galvanizing. The integration and sharing of the three major parts of the material equipment, the annealing and reduction equipment, and the zinc pot equipment reduces the investment capital and risk of the entrepreneur, and solves the high cost and economic pressure of building a separate production line.
