Read MoreThe drawing process of the product drawing process has a great influence on the product function. Generally, a large total surface reduction rate of about 90% (see area reduction rate) and a small pass surface reduction rate (about less than 23%) are selected to ensure the endurance of the product. On the high strength spring steel wire, drawing should control the exit temperature of each passage of the steel wire is lower than 150℃, to avoid the steel wire due to strain aging and appear to change the crack, which is the formation of steel wire scrap the primary disadvantage.

drywall screws 6 x 1 1 4Large roll galvanized wire is the use of low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes, in the use of is more widely. The temperature of large roll galvanized wire for electroplating should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

Read MoreThe management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

Post time: 07-06-22Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
In moist air, a dense basic zinc carbonate film forms on the surface of zinc. Zinc coating belongs to the anodic coating, it is mainly used to prevent the corrosion of steel, its protective performance and the thickness of the coating is very important. The protective and decorative properties of zinc coating can be improved significantly after passivation treatment, dyeing or coating with light protection agent.
