Raw material

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Q195 wire rod---this type of wire rod has less impurities so it  very suit for drawing. Q195 material's chemical component is nearly same as SAE1008 and SAE 1006. Q195 material chemical component : 

C≤0.07; S≤0.023; Si≤0.09; Mn≤0.32; P≤0.025.

Galvanized wire production 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 annealed

 

Anneal is to low the tensile strength of wire . The stove is solid . The architecture of anneal stove is cuboid . Different thickness of wire require different temperature . Range is from 700℃to 900℃ . Output of the anneal stove , the tensile strength is 400N~500N .

 

3 . 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.

Electro galvanized is a chemical reaction. One chlorhydric acid pool is enough. However, hot-dipped is a physical reaction, it needs two chlorhydric acid pool and two water pool for the preparation of galvanization.
