galvanized wire

wire gauge:8--22#(other speccification can be made as customer's request).

type:electro galvanized wire and hot dipped galvanized wire.

material:Q195 Q235.SAE 1006/1008 ECT.

packing: 1--1000kg /coil (as customer's request).

application:this kind of wire is extensively used in construction binding wire woven mesh wire express way fencing mesh wire ect.

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.

Galvanized wire's second stage is anneal.

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.

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.

Galvanized wire's fourth stage: Zinc coating

After the chlorhydric acid pool, water pool is also necessary.
