Introduction

Black Annealed Wire is also called black iron wire, soft annealed wire and annealed iron wire. It

includes annealed wire and black oiled wire. Black annealed iron wire gets its name from its plain black color.

Annealed wire is obtained by means of thermal annealing. Annealed wire offers excellent flexibility and softness through the process of oxygen free annealing. Black Annealed Wire is stored in coils or spools of a varying weights and dimensions depending on the purposes.

1. Material Q195 

Black annealing 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. Generally.

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. 

Standard coil  10kg,25kg,50kg and so on .we can coiled with customer's order.
