Introduction

Material Q**5

 Galvanized wire and all other wire mesh are manufactured by wire rod. Wanlida buy this material from SHANXI ZHONGYANG IRON

and STEEL CO., LTD, which is the biggest steel factory in China. The type of wire rod is Q**5, element composition is as follows:

C≤0.*7; S≤0.**3; Si≤0.*9; Mn≤0.*2; P≤0.**5.Because This type of wire rod has less Impurities, Q**5 is fit for drawing.

The diameter is 6.5mm. Generally, Daily output of Wanlida is **0 tons.(electro and hot-dipped are separately *0 tons)

Drawing

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.

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 **0°C to **0°C. Output of the anneal stove, the tensile strength is **0N~**0N.

Chlorhydric acid washing 

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 *7%. In the Chlorhydric acid pool,

there is a caldron used for the emission of vapor.

Standard coil  *0kg,*5kg,*0kg and so on .we can coiled with customer’s order.
