Process specifications

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 is offered energy by a electromotor. 0.9mm (max) can be “eat” when the wire crosses a mold. There is no loss of weight during drawing.

2). Galvanized wire’s second stage is annealed

Anneal is to low the tensile strength of wire. The stove is solid and built with red bricks. The architecture of anneal stove is cuboids. Different thickness of wire requires different temperature. Range is from 700℃to 900℃. Output of the anneal stove, the tensile strength is 400N~500N.

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.

Electro galvanized is a chemical reaction. One chlorhydric acid pool is enough. However, hot-dipped is a physical reaction, it needs two chlorhydric acid pool and two water pool for the preparation of galvanization.

4). Galvanized wire’s fourth stage: Zinc coating
