Wholesales Electro Galvanized Iron Wire Cutting Wire

Hot Sales High Quality Bright Galvanized Iron Wire With High Tensile Strength

1,Raw Material(Wire Rod)Galvanized Wire and all other Wire Mesh are manufactured by wire rod. The type of wire rod is Q195, Element Composition is as follows:C≤0.07; S≤0.023; Si≤0.09; Mn≤0.32; P≤0.025.Because This type of wire rod has less Impurities, Q195 is fit for drawing. The diameter is 6.5mm.

2,Types:

3,Application:

1) construction binding wire 

2) wire mesh weaving

3) making express way fence 

4) chain link fence 

5) handcrafts   

4,Process:

1)Galvanized wire's first stage is Drawing.

There are two kinds of drawing machine: powder drawing and water drawing. powder drawing is fit for junior drawing(6.5mm~4.0mm). One powder drawing machine has 4 tanks and 4 molds. One tank is matched with a mold. Each of them are offered energy by a electromotor. 0.9mm(max)can be "eat" when the wire cross a mold. There are no loss of weight during drawing.

2)Galvanized wire's second stage is Anneal.

Anneal is to low the tensile strength of wire. The stove is solid and built with red bricks. The architecture of anneal stove is cuboid. Different thickness of wire require different temperature. Range is from 700°C to 900°C. Output of the anneal stove, the tensile strength is 400N~600N.

3)Galvanized wire's third stage is achlorhydria acid washing.

After the draw and anneal, the wire is thinner, softer but also much more dirty. It needs achlorhydric acid washing to remove the impurities. Achlorhydric acid washing requires water pool and achlorhydric acid pool. The density of achlorhydric acid is 17%. In the Achlorhydric acid pool, there is a chaldron used for the emission of vapor.

4)Galvanized wire's fourth stage: Zinc coating 

After the achlorhydric acid pool, water pool is also necessary. In the zinc pool, displacement reaction is chemical and uniformly distributed. The surface of wire is smooth. Because wire cross the zinc pool fast, abundant zinc coating requires 4 zinc pools.
