Hot Dipped Continuous Wire Galvanizing Line For Zinc Aluminium Galfan Wire

We provide hot dipped galvanized wire production line which is producing hot dipped galvanized

steel wire,it is widely used in making wire mesh fence products and construction field.

Hot dipped continuous galvanizing line characteristics

Wire take up machine: adopts inverted plum blossom take-up unit, which adopts variable frequency

speed-regulating motor, and the take-up speed is adjustable. Each take-up reel is equipped with a

4.0KW and a 0.75KW motor. When the wire is taken up, the wire is flat. The wiring is stable and

the disc weight is 800-1000kg, which is convenient for workers to operate.

Hot dipped continuous galvanizing line theory

1) the steel structure of the furnace body adopts the overall frame dimensions: L26000*W2400*H1800(mm)

2) the net width of the furnace: 1250 (mm), the distance of the steel wire in the furnace; 35 mm;

3) fuel type: mixed gas or converter gas (heat value: ≥ 1250 KCal)

4) contact pressure: normal 0.012MPa, fluctuation ≤ 5% pressure value.

5) contact pipe diameter: DN80

6) using a four-stage assembly of countercurrent furnace type, direct-fired type and premixed burners are

    used together to control the atmosphere and pressure in the furnace

Hot dipped continuous galvanizing line advantage and selling points

1. The heat treatment furnace adopts a countercurrent open flame heating type furnace. The furnace body is

a three-stage combination. The preheating section, the heating section, the heating section and the heating

section are respectively set up from the inlet. The heating of each section is relatively independent and affects

each other. According to the requirements of the heat treatment process, the furnace temperature and

atmosphere can be set in stages to meet the processing requirements.

2. The heat treatment furnace steel wire inlet and outlet furnace door is designed with mechanical transmission

device, and the furnace door is opened to facilitate the structure to reduce the cold air intake and fire.

3. The heat treatment furnace adopts an energy-efficient waste heat recovery device. The high-temperature

gas discharged from the furnace is recovered by the heat exchanger, and the combustion air is used for the

burner to improve the thermal efficiency of the furnace to save energy. Generally, the combustion air per

combustion Increasing 100 °C saves 5% of fuel.

4. heat treatment furnace temperature control

(a) The control system has two control modes, manual and automatic. The main control PLC adopts

the Siemens S300 series products to ensure accurate and stable control.

(b) The temperature and air-fuel ratio of each section can be adjusted according to the process requirements.

(c) Features of the equipment: The open flame annealing furnace adopts multiple burner heating methods on

both sides, the heating temperature is uniform, the surface of the steel wire is not easily damaged, the pass

rate is high, the temperature control accuracy in the furnace is high, below 1000 °C, according to steel

The actual condition of the wire regulates the temperature and is stable and reliable. The two-stage heating

zone is completely made according to the heat treatment curve of the steel wire to ensure complete phase

transformation of the steel wire in the furnace, the temperature transition is stable, the pass rate of the pass

bar can reach more than 99%, the oxidation burn rate is 0.145%, and the lateral temperature difference

in the furnace is ±2. °C.
