Automatic Steel
Galvanization Production Line: Advanced Continuous Coating Technology for Superior Corrosion Protection This state-of-the-art
continuous galvanizing line is engineered for high-efficiency, consistent, and reliable surface treatment of steel strips through zinc or zinc-aluminum alloy coating. Designed for industrial applications in the stainless steel and metal processing sectors, this fully automated system ensures a safe, stable, and precision-controlled environment that enhances product durability and performance. Whether used in automotive manufacturing, construction, or appliance production, the line delivers uniform coating quality while minimizing waste and operational downtime. Key Features: - Integrated PLC-based electrical control system with S71500 program algorithm for precise speed synchronization - Encoder-assisted strip transmission mechanism for accurate tension management - Advanced unwinder with dynamic tension regulation to prevent slippage or breakage - Constant tension winding technology to maintain coil integrity and prevent deformation - Multi-stage cleaning and pre-treatment process to remove oils, rust, and oxides before coating - Real-time monitoring of strip speed, thickness, coil diameter, and tension parameters Detailed Description: The automatic steel galvanizing production line utilizes a hot-dip galvanizing method that applies a protective metallic layer onto cold-rolled steel coils. This process significantly improves corrosion resistance, making it ideal for outdoor and harsh environmental applications. The system’s programmable logic controller (PLC) enables seamless coordination between each stage—from entry tensioning to exit coiling—ensuring optimal adhesion and uniformity of the zinc or zinc-aluminum alloy coating. By maintaining constant tension throughout the entire galvanizing cycle, the line prevents defects such as wrinkles, edge cracks, or uneven film thickness. Additionally, the advanced cleaning section removes contaminants like iron oxide and residual grease, guaranteeing superior bonding between the base metal and the coating material. With customizable settings for strip width, thickness, and speed, the system adapts efficiently to various production requirements across global markets. Ideal Applications: This
continuous galvanizing solution is widely adopted in industries requiring durable, long-lasting metal products.
