ال steel rolling plant is a critical facility in modern metallurgy, transforming raw steel into high-precision products like sheets, الحانات, and coils. This article delves into the operational principles, equipment, and cutting-edge technologies employed in these plants, with a focus on مصانع الدرفلة الساخنة and their auxiliary systems.
1. The Steel Rolling Process: From Billets to Finished Products
في 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. Key stages include:
- Roughing: Initial thickness reduction via horizontal/vertical rolls
- Intermediate rolling: Precision dimension control
- Finishing: Final surface quality and tolerances
