Precautions for Galvanization and Annealing in Galvanized Wire Production Process

Galvanized Wire

Annealing and galvanizing are the most important steps in the production process of Galvanized Wire. Annealing is to ensure the cleanliness of the wire and improve the quality of the wire. Zinc plating is a process to ensure corrosion and corrosion of the wire. It is an important step in determining the service life and use of Galvanized Wire.

Galvanized Wire

After the general annealing, it is galvanized. There are some things that need our attention in these two production processes. Doing so can ensure the high standards in the production process of Galvanized Wire products, and it is also the important content that determines the final high quality of the product.

Galvanized Wire

Generally, the wire after drawing is preferably processed within three days. If it is not possible, it needs to be automatically short-term stopped. The annealed Galvanized Wire should be pickled and rust-proof before zinc; only pickled and rust-proof wire should be Zinc is applied in the fastest time; the zinc plating time of the pickled and rust-proof wire is within 24 hours; the iron wire after drawing is oil-free after annealing, and the operator wears clean overalls during the process of zincing. Work with gloves.

Galvanized Wire

Galvanized Wire pickling is mostly acid washed with hydrochloric acid, the concentration of hydrochloric acid is 20%, the temperature is 30 degrees, the acid pickling solution can be accompanied by a certain corrosion inhibitor product, the pickling can not be excessive, and it should be put in the specified time within the specified time. The internal extraction, the concentration of the pickling solution and the pickling time are controlled in the prescribed process. Excessive pickling can cause Galvanized Wire to be hydrogen embrittled, with reduced corrosion resistance and reduced brightness, so beware of excessive pickling.

Galvanized Wire

Why does Galvanized Wire have to be rust-proof in addition to zinc? This problem is very doubtful for many friends. It is because the surface of the wire is easily oxidized to form an oxide after pickling. The anti-rust treatment after pickling can prolong the storage time of the zinc on the wire, and extend the traditional zinc time from ten minutes to several tens of minutes to less than 24 hours. At the same time, it can ensure that the bonding force of zinc layer and wire meets the requirements of industry standards.
