El steel rolling plant is a critical facility in modern metallurgy, transforming raw steel into high-precision products like sheets, verja, y bobinas. This article delves into the operational principles, equipo, and cutting-edge technologies employed in these plants, with a focus on molinos calientes and their auxiliary systems.
1. The Steel Rolling Process: From Billets to Finished Products
In a steel rolling plant, the process typically begins with reheating billets or slabs to 1100–1250°C in a furnace. The heated material is then passed through a series of rolling stands to reduce thickness and achieve the desired shape. Las etapas clave incluyen:
- Desbaste: Initial thickness reduction via horizontal/vertical rolls
- Intermediate rolling: Precision dimension control
- Refinamiento: Final surface quality and tolerances
