Production equipment and production method for hot galvanized packaging steel strip, and hot galvanized packaging steel strip

Abstract

The invention provides production equipment and production method for a hot galvanized packaging steel strip, and the hot galvanized packaging steel strip. The production equipment comprises an uncoiler, a butt welding machine, a first tension device, a feeding loop, a second tension device, a slitting machine, an edge trimmer, a third tension device, a heat treatment furnace, a zinc hot melting pot, an air cooling device, a water cooling device, a fourth tension device, a roller coater, a drying and curing machine, a discharging loop, a fifth independent tension device and a coiler, all of which are sequentially arranged. The production equipment and production method for the hot galvanized packaging steel strip, and the hot galvanized packaging steel strip have the beneficial effects that the steel strip with a first width is cut by the slitting machine in the width direction after being fed to form a plurality of steel strips with a second width, and the steel strips with the secondwidth are conveyed into the zinc hot melting pot for hot galvanizing treatment, so that each surface of each steel strip with the second width is galvanized, and the corrosion resistance requirementof each surface of the steel strip is better met accordingly.

Description

technical field [0001] The disclosure relates to the technical field of hot-dip galvanizing for steel strips, and in particular to a production equipment and method for hot-dip galvanizing packed steel strips and hot-dip galvanized packed steel strips. 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. In the prior art, the medium and wide steel strips are first galvanized in a hot-melt galvanizing pot, so that each surface of the medium and wide steel strips is galvanized, and the galvanized medium and wide steel strips are cut into The thin steel strip that meets the required width of the packing strip....

AI Technical Summary

Problems solved by technology

In the prior art, the medium and wide steel strips are first galvanized in a hot-melt galvanizing pot, so that each surface of the medium and wide steel strips is galvanized, and the galvanized medium and wide steel strips are cut into The thin steel strip that meets the required width of the packing strip. Since the narrow steel strip is cut from the galvanized medium-width steel strip, the cutting surface of the narrow steel strip has not been galvanized, so the narrow steel strip is used in the packaging After the field, due to the unstable use environment of the strapping steel strip, the ungalvanized side of the strapping steel strap is easily corroded in harsh environments, which affects the use strength requirements of the strapping steel strap
