Steel hot rolling mill machinery is a cornerstone of modern metallurgy, transforming raw steel into high-quality sheets, assiettes, and coils. This process involves heating steel above its recrystallization temperature and passing it through rollers to achieve desired thickness and mechanical properties. Dans cet article, we delve into the intricacies of machines de laminoir à chaud en acier, its components, and the technical parameters that define its performance.
What is Steel Hot Rolling Mill Machinery?
Machines de laminoir à chaud en acier refers to the equipment used in the hot rolling process, where steel slabs or billets are heated to approximately 1200°C and rolled into thinner cross-sections. This machinery includes furnaces, rolling stands, descaling systems, lits de refroidissement, and coiling equipment. Companies like HANI TECH specialize in designing and manufacturing these systems for global metallurgical plants.
Key Components of Hot Rolling Mills
- Fours de réchauffage: Heats steel to the optimal rolling temperature.
- Moulin à ébourignage: Reduces slab thickness through multiple passes.
- Moulin à finition: Achieves final dimensions and surface quality.
- Circuit de refroidissement: Contrôle les taux de refroidissement pour améliorer les propriétés des matériaux.
- Coiler: Winds the rolled steel into coils for storage and transport.
