Hot dip galvanizing production line is to immerse derusted steel wire into about 500°C melted zinc solution, so the surface of steel wire is coated with zinc layer and realizes corrosion prevention. Galvanization layer is usually over 35μm, and even reaches 200μm. Hot dip galvanization boasts goodcovering power, compact coating and free from organic matters. Therefore,zinc layer is able to protect steel wire for 10-50 years effectively.

Features: annealing furnace adopts electric heating tube furnace, which ischaracterized by internal radiation heating, n zone temperature controleven lonqitudinal and horizontal temperature in heating furnace. Heating ofhot dip galvanization is controlled by silicon-controlled smart meter.
