Redefining Lifting in Galvanizing Processes
Lifting Solutions for Galvanizing Lines
The galvanizing process is one of the harshest operations in metal manufacturing and requires equipment that can endure extreme heat, oversized loads, and a highly acidic environment.
Fortunately, American Crane and Equipment Corp. is proud to meet the demanding material handling needs of galvanizing lines, steel rolling mills, and other critical equipment.
At American Crane, we are confident in our ability to produce complex custom equipment or standard replacement components and parts that support lifting applications of all kinds, with capacities of up to 1,000 tons.
Our team is recognized as an industry leader in overhead cranes, wire rope hoists, and many other lifting products. Let us help you tackle the most rigid material-handling challenges quickly and confidently.
What Is Galvanizing?
The environment is incredibly hostile in a galvanizing line, containing numerous harmful substances that can wreak havoc on equipment and products. Therefore, cranes and other line equipment, such as tanks, filtration systems, and furnaces, must be designed to withstand these challenging conditions.
It is crucial to use cranes built to endure caustic environments to guarantee that they last longer and perform more reliably with minimal maintenance and downtime. Using substandard equipment in such conditions is not an option, as it can lead to significant damage and disruption to the entire process.
The cranes used in galvanizing lines are always custom-designed to meet the application’s specific requirements. They are made with galvanized or stainless steel tracks to prevent rust and premature corrosion. Furthermore, galvanized solid bar runway electrification and other challenging design elements are utilized to help minimize the damaging effects on the environment.
These measures are essential to ensure the equipment remains robust and reliable within the demanding galvanizing line. The result is an incredibly efficient and effective system that can withstand harsh conditions and produce quality products consistently. It is imperative to take all necessary precautions to protect the equipment and the product, as the consequences of using inferior equipment can be catastrophic.
Our state-of-the-art galvanizing equipment is specifically designed to withstand the toughest corrosive challenges of the galvanizing process. We prioritize:
- Cranes Resistant to Caustic Conditions: Engineered for enhanced durability and less frequent maintenance.
- Customized Equipment Solutions: Featuring galvanized or stainless steel tracks to prevent premature wear.
- Robust Design Innovations: Incorporating elements like galvanized solid bar runway electrification for added resilience.
- Reliable and Long-Lasting Performance: Ensuring equipment longevity even in the toughest environments.
Understanding Galvanizing Dynamics
The Galvanizing Line: A Detailed Overview
The galvanizing line is a rigorous and challenging process that involves working in a highly acidic environment. It is more hands-on than fabrication, where structural steel is carefully suspended from crane hoists and immersed in solutions. The process involves several crucial steps that must be followed meticulously to ensure the desired outcome.
- Initial Caustic Cleaning: Immersing steel in a caustic solution for deep cleansing.
- Rinsing and Pickling Phases: Removing surface oxides and preparing for zinc adherence.
- Flux Solution Application: Final oxidation cleaning before zinc coating.
- Pre-Zinc Drying: Essential preparation for zinc application.
- Zinc Bath Immersion: The core step for steel galvanization.
- Cooling and Quality Inspection: Ensuring the finished product meets standards.
- High-Speed Continuous Sheet Galvanizing: For thin-coated steel sheets, ideal for interior use.
The process of continuous sheet galvanizing requires unrolling the sheet and passing it through rapid cleaning and molten zinc baths at high speeds of up to 500 feet per minute. The sheet is then recoiled after being dried. The resulting sheets have a thin coating of 0.45 oz. per side, making them an excellent choice for indoor use, unless they are painted after galvanizing.
