20 gauge gi binding wire       making process

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. Generally, Daily output is 120 tons.(electro and hot-dipped are separately 60 tons)

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.

Water draw is used for senior draw.(≤4.0mm)The container is filled with water, soap and 8 molds. Compared with powder draw, water draw can save lots of room and the wire cannot be broken.

After drawing, the wire is thinner, but also very hard. The tensile strength is about 700N. These wire can be used to produce nail and mesh panel. For galvanized wire, it still need annealing

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.

Galvanized wire's third stage is chlorhydric acid washing.

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

Galvanized wire's fourth stage: Zinc coating

After the chlorhydric acid pool, water pool is also necessary.
