Black Annealed U Type Wire for Construction Binding

Black Annealed U Type Wire for Construction Binding

Black annealed U type Wires are a kind of wires which are cold drawn using low carbon steel wire, they are very popular in Japan market, using for construction. It's widely used in construction or daily use as binding material. Besides, Mainly used in construction, mining, chemical, welded mesh, welded hangers, and then processing. Soft annealed wire, increase flexibility, doing construction tie wire, and has good steel bandings. Green Coating Welded Fence Panel, Galvanized Chain Link Fence for Play Yard, Galvanized Hexagonal Wire Netting and Euro Fence.

Specification:
Wire Diameter: 2.8mm, 3.2mm, 4.0mm

Length:700mm, 1000mm, 2000mm, 2450mm, 4000mm, 5000mm.

Packing:10kg/bundle, 13kg/bundle, then by pallet or according to your needs.

Production Process

The rolling of hot metal into 6.5mm thick steel or wire rod,then put it into the drawing device is pulled into a different diameter line,and gradually reduce the aperture drawing plate, cooling, annealing, coating and other processing technology into a variety of different specifications

of the wire.

A. Material Q195

Black annealling 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, Daily output of Wanlida is 120 tons.

B. 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.

C. 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.

Wire diameter: 0.25-6.0mm.

Tensile strength: 300-450Mpa.

Coil weight: 1-50kg or as your require.

Advantage: More soft,more strong flexibility, the softness of the uniform, color consistency.

Purpose: Widely used construction.
