Businesses aiming at improving the efficacy and quality of their galvanizing procedures should think about investing in automatic hot dip galvanizing plants. The latest technology in automatic plants enables the automation of many galvanizing procedures, resulting in greater output and uniform outcomes.
Understanding the components of these plants is very important for making decisions regarding implementation and operation. In this blog, we will understand the essential components of Automatic galvanizing plants, and also the function and benefit of each component.
- Pre-Treatment section
The first stage in the galvanizing process is the pre-treatment section. This stage is important for preparing metal or in simple terms steel products for coating. The things which are included in this section are:
- Degreasing Tanks
These tanks help in removing the excess oil, grease, and other oily substances which are present on the steel surface. A completely clean surface is very essential before the zinc coating.
- Pickling Tanks
These tanks are filled with acid solutions and help in removing rust, scale or any such oxide from the steel. The use of this tank provides a proper smooth and clean surface for galvanizing.
- Rinsing Tanks
After pickling the steel with acid, the steel is again rinsed in the tank to remove the leftover acid from the surface.
The benefits of the Pre-Treatment section are:
- Provides clean and smooth steel surfaces.
- Will help in giving the proper zinc coating.
- Will improve the quality of the final product.
- Fluxing section
In this section, the clean steel is dipped into a flux solution, which is simply, ammonium chloride. This step is important as it prevents oxidation. The different components of this section are:
- Flux tanks
These tanks have flux solutions, which help in promoting the bond of zinc and steel.
- Drying ovens
Steel parts after fluxing are dried properly in this oven to remove any sort of residual moisture and to ensure uniform zinc coating.
The benefits of the fluxing section are:
- It helps prevent oxidation.
- It helps in providing a strong bond between iron and zinc.
- It helps in improving the quality and durability of the galvanized coating.
- Galvanizing Kettle
This is the most important component of the galvanization process. It has molten zinc which has a temperature around 450°C.
The different components of this include:
- Kettle
The kettle which is used is made up of steel and has ceramic linings, it is used to hold molten zinc for the dipping process.
- Heating System
This system helps in ensuring that the zinc is at the appropriate temperature which is very important for effective galvanizing.
- Dipping mechanism
This mechanism is used for raising the steel parts into and out of the molten zinc, to provide even coating.
The benefits of Galvanizing Kettles are:
- It helps in providing uniform zinc coating.
- It increases corrosion resistance.
- It ensures the durability of the steel products.
- Cooling and Quenching section
After coating the steel parts with zinc, the parts need to be cooled and solidified. This section of the galvanizing process includes:
- Cooling tanks
In this tank, the galvanized steel is cooled using either water or air to solidify the zinc coating properly.
- Quenching tanks
This tank is mostly filled with passivation solution, to enhance the appearance and corrosion resistance property of the zinc coating.
The benefits of the Cooling and Quenching section include:
- The rapid cooling helps in solidifying the zinc coating.
- The passivation which is provided helps in improving corrosion resistance and appearance.
- This section provides durability to the galvanized products.
- Post-treatment section
This section involves additional processes, to improve the quality and finish of the galvanized products. The processes involved are:
- Inspection and finishing
The automated galvanizing plants, in this process, inspect the galvanized products to ensure that there are no defects or uneven coating. Finishing the product includes removing the excess zinc and also adding protective coatings.
The benefits of the Post-treatment section are:
- This section ensures that there is no defect in the product.
- It helps in improving the appearance and durability of the products.
- It prepares the product for safe transportation.
- Control systems
There are advanced control systems which are integrated into the automatic galvanizing plants, to ensure precision and efficiency.
- Programmable logic controllers
These controllers control the entire process from pre-treatment to post-treatment ensuring that each stage is operating correctly.
- Monitoring systems
These systems provide real-time data based on process parameters, which allows adjustments to maintain the optimal temperature.
- Safety systems
They help in protecting the workers and different instruments from any potential hazard.
Benefits of control systems
- It helps in improving the operational efficiency.
- It provides consistent quality and adherence to standards.
- Provides safety and reduces the risk of accidents.
