1. RAW MATERIALS
The diameter of wire rod, as a starting material, is mostly
**6 mm. In this project, it is presumed that wire rod having a
diameter of 5.5mm, which is most popular, is used.
As for the secondary materials required, they include chemical
reagents for pickling–mainly hydrochloric acid.
2. Process Description
A surface coating of iron oxide which forms on steel when it
is heated must be removed from the wire rod and this oxidation
layer will be removed by cleaning machine.
The clean wire rod is coated with lime, borax, or phosphate.
This coating prevents rusting, neutralizes any remaining traces of
acid, and helps lubricants adhere to the wire rod when it is made
into wire.
One end of the coated wire rod is shaped to a point. This end
is inserted like a thread going through the eye of a needle into a
die consisting of a very hard central nib made of tungsten carbide
surrounded by a steel holder. The wire rod is lubricated with oil
or soap and is pulled through the die to reduce the diameter. This
process is known as drawing. A series of dies are used to reduce
the wire rod from its original size to the desired size of the
wire. For binding wire, the diameter is typically 0.*1 mm.
Drawing the wire causes it to become hard and stiff. To make
it pliable, it is heated, a process known as annealing.
Wire to be made into barbed wire
is usually galvanized (coated with zinc) in order to prevent
weathering. The wire must be perfectly clean and dry to be properly
galvanized. First it is cleaned in a bath of hot, dilute
hydrochloric acid, and then rinsed with hot water. It then passes
through a solution of hot zinc chloride or ammonium chloride to
prevent rust from forming as it is dried. After drying, the wire
passes through bath molten zinc. Excess zinc is wiped off and the
coated wire is allowed to cool.
