Annealer wire drawing machines are used in the wire industry to reduce the cross-section of wires and make them suitable for various applications. These machines typically consist of a drawing section and an annealing section. The drawing section reduces the wire diameter through a series of drawing dies, while the annealing section softens the wire to improve its ductility and reduce brittleness.

Here are some key points about annealer wire drawing machines:

Principle: Annealer wire drawing machines work by reducing the wire diameter through a series of drawing dies. The wire is elongated and its cross-section is reduced in each drawing step.

Materials: These machines are commonly used for drawing copper and copper alloys, as well as aluminum and aluminum alloys.

Machine Types: Annealer wire drawing machines are divided into three main types based on the wire diameter they can handle:

Rod drawing machines: Used for larger wire diameters, typically starting from 8 mm for copper and 9.5 mm for aluminum.
Medium wire drawing machines: Suitable for intermediate wire diameters, ranging from 0.5 mm to 3 mm.
Fine wire drawing machines: Designed for drawing very thin wires, with diameters as small as 0.03 mm.
Annealing: Annealing is an essential step in the wire drawing process. After the wire is drawn to the desired diameter, it is passed through an annealing section. The annealer heats the wire to a minimum temperature of 300°C to recrystallize the structure and eliminate the hardness caused by cold deformation. Steam or nitrogen is often injected to prevent oxidation during annealing. The wire is then cooled down before being spooled.

Advantages of Annealer Wire Drawing Machines:

Dual frequency conversion: These machines often feature dual frequency conversion, which allows for better stability and minimizes the chance of wire breakage.
Spooling device flexibility: Annealer wire drawing machines can accommodate different spool sizes, providing better stability during winding.
Traversing methods: These machines offer multiple traversing methods, such as I-shaped or cone-shaped, and may include optical fiber measurement devices for automatic traversing.
Excellent wire surface quality: Annealer wire drawing machines are designed to produce wires with high surface quality.
Energy savings: These machines are often designed with energy-saving features.
