Galvanized Iron Wire Production: Key Considerations for Large and Small Coils
In galvanized iron wire production, coil size (large vs. small) directly affects the production process, equipment configuration, operation flow, quality control and cost-effectiveness. The following are the key differences that should be paid attention to when producing large and small volumes:
Large Coil Considerations:The core of large coil (often over 500kg) production is stability and efficiency. First, raw material selection must be high-standard to ensure consistent wire rod properties and minimize breakage risk. Second, annealing and galvanizing processes require extreme precision. Furnace temperature, zinc bath temperature, and dipping time must be meticulously controlled to ensure consistent core-to-surface properties and coating thickness. Winding is critical; constant tension and neat coil formation are essential to prevent collapsing or "loudspeaker" coils, demanding high equipment rigidity.
Small Coil Considerations:Small coil (often tens to hundreds of kg) production emphasizes flexibility and surface quality. Higher frequency of coil changes makes production continuity and changeover efficiency vital, requiring optimized workflows. Coating uniformity and surface finish are quality priorities, necessitating prevention of zinc ash buildup or scratches. Packaging is particularly important for small coils. It must be secure and neat, using high-strength film or straps to prevent loosening during transit, with clear product identification.
In summary, large coils prioritize internal quality and production stability, while small coils require excellent appearance and secure packaging.
