Galvanizing Tank/Galvanizing Kettle/Zinc Kettle
Zinc Kettle / Galvanized Kettle for Hot-Dip Galvanizing Plants
Ainc kettle (also called a galvanizing kettle, galvanizing tank, or molten zinc bath) is the core vessel of hot dip galvanizing equipment. It holds molten zinc at 438-460 C (820-860 F), into which cleaned steel parts are submerged to form a durable zinc-iron alloy coating.
The kettle must withstand continuous thermal stress, the corrosive attack of liquid zinc on steel, and the mechanical load of heavy workpieces â?? making material selection and welding quality the two most critical factors in kettle longevity.
Hebei Annuo manufactures three main kettle types to suit different galvanizing processes:
Batch galvanizing kettles for structural steel, fabrications, and general-purpose HDG plants
Continuous galvanizing kettles for wire, strip, and tube lines
Spin galvanizing kettles for small fasteners, nuts, bolts, and hardware
Key Features of Our Galvanized Kettle
XG08 Low-Alloy Steel - The Best Kettle Material in China
The material we use is XG08, which is the best steel sheet for manufacturing galvanizing kettles in China. It contains tightly controlled levels of:
Carbon (C): - 0.08%
Silicon (Si): - 0.10%
Sulphur (S): - 0.008%
Phosphorus (P): - 0.010%
Lower Si and C content directly reduces the Fe-Zn reaction rate at the kettle wall, cutting wear by up to 40% compared with standard structural steel. Standard structural steels typically contain 0.20-0.35% Si, which can increase the corrosion rate by 2-4 versus XG08.
One-Piece Hydraulic Forming No Horizontal Bottom Weld
The U-shaped kettle body is hydraulically formed in a single press operation, eliminating horizontal weld seams at the high-stress bottom zone. Horizontal welds are the most common failure point in galvanizing kettles; removing them is the single most effective measure for extending service life.
100% Ultrasonic Testing at Two Stages
Every steel plate is ultrasonically scanned before cutting. Every completed weld seam is 100% UT-tested after fabrication. No kettle leaves the factory without passing full weld integrity verification.
