Black Annealed Wire

1. Material Q195
Black annealling 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 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 of Wanlida is 120 tons.
2. 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.
3. Annealing
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.
