How to Achieve Energy Saving of Hot-dip Galvanizing Equipment

With the development of industry, hot dip galvanizing design has been used in many fields, the advantages of hot dip galvanizing are the long anti-corrosion life, adapt to a wide range of environments has been a very popular anti-corrosion treatment method. It is widely used in electric power towers, communication towers, railroads, highway guardrails, street light poles, marine components, building steel components, substation appurtenances, light industry, etc.

Hot-dip galvanizing has a long anti-corrosion life, but the anti-corrosion life varies in different environments: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs, and 30 years in cities.

The principle of hot-dip galvanizing: the iron parts are cleaned, then solvent-treated, dried, and immersed in a zinc solution, where the iron reacts with the molten zinc to produce an alloyed zinc layer. The process is: degreasing – washing – pickling – assisted plating – drying – hot-dip galvanizing – separation – cooling passivation.

The thickness of the alloyed layer of hot-dip galvanizing depends on the chemical composition of the steel such as silicon content, the size of the cross-sectional area of the steel, the roughness of the steel surface, the temperature of the zinc pot, the time of zinc dipping, the speed of cooling, and the cold rolling deformation.

Advantages of hot-dip galvanizing

1. Good reliability: the galvanized layer is metallurgically bonded to the steel and becomes part of the steel surface, so the durability of the coating is more reliable.

2. Durable: In suburban environments, the standard hot-dip galvanized rust protection thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized rust protection layer can be maintained for 20 years without repair.

3. Low treatment cost: the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings.

4. Comprehensive protection: every part of the plated part can be coated with zinc, even in depressions, sharp corners, and hidden places.

5, the toughness of the coating: the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.

6. Low initial cost: In general, the cost of hot-dip galvanizing is lower than applying other protective coatings for the simple reason that other protective coatings such as sanding and painting are labor-intensive processes, whereas hot-dip galvanizing is a highly mechanized, closely controlled in-plant process.

7.Saving time and effort: the galvanizing process is faster than other coating methods and avoids the time required to paint on the site after installation.

8. Reliability: Hot-dip galvanizing is generally performed in accordance with BS EN ISO 1461, which specifies a minimum zinc layer thickness, so its rust resistance and performance are reliable and predictable.

9. Simple and convenient inspection: The hot-dip galvanized layer can be tested visually and with a simple, non-destructive coating thickness gauge.

How to choose a good hot-dip galvanizing kettle？

As a galvanizing equipment supplier,we can tell you there are many precautions when choosing to buy a galvanizing pot. The first thing you need to pay attention to is: the size, material, heat source, and shape of the galvanized pot and other auxiliary equipment, so as to ensure normal operation after the purchase. Then you need to consider that there are many types of galvanizing pots, and the galvanizing pots used in different industries are also different. You should choose suitable equipment according to the needs of the factory. According to the type of workpiece to be galvanized, the size of the workpiece, the output, and the size of the factory building choose a zinc pot with a suitable size.

Nowadays, some manufacturers pay great attention to environmental protection, so environmental protection equipment is also very important. With the current hot-dip galvanizing equipment has been widely used. At present, the galvanized pot is more space-saving and can be produced more effectively in the production process.

Some galvanizing kettles used in the past are made of iron. Now there are more materials available, and the heating performance has also become faster. The operating environment can also be the best, simple, and the heating is more uniform. The accuracy of temperature control is relatively high.
