High Carbon Spring Wire , Carbon Steel Welding Wire 0.2mm-4mm
Wire is available in both low carbon and high carbon quality steel. Low carbon wire is available as galvanized, bright, and annealed with wire processing options that include cold heading and straighten and cut. Used primarily for components in applications such as the construction, automotive and military. Carbon steel wire comes in diameters that range from 0.008” to 1.25” depending on the type. This type of carbon wire forms easily and can handle moderate flattening and bending.
Main production processes for galvanized wire are as follows:
Step 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. Powder is used as lubricant, which is made of soap and butter. Mold is hidden behind the powder.
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.
Step 2. Galvanized wire's second stage is anneal:
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
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.
Step 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.
Step 4 . Galvanized wire's fourth stage: Zinc coating:
After the chlorhydric acid pool, water pool is also necessary. In the zinc pool, displacement reaction is chemical and uniformly distributed. The surface of wire is smooth. Because wire cross the zinc pool fast, abundant zinc coating requires 4 zinc pools.
1. Excellent flexibility and softness
2. Suitable usage : The wires are extensively used in construction, handicrafts, woven wire mesh, express way fencing mesh, packaging of products ,Net making , winding , baling , hanging and other daily uses.
1)Hot-dip galvanized iron wire
Hot-dip galvanized iron wire is made with choice low carbon steel wire, through wire drawing, acid washing and rust removing, annealing and coiling. It’s mainly used in construction, handicrafts, woven wire mesh, express way fencing mesh, packaging of products and other daily uses.
