Le laminoir d'acier est une pierre angulaire de la métallurgie moderne, transforming raw steel into precise shapes for construction, automobile, et applications industrielles. Cet article approfondit les subtilités techniques de rouleau operations while integrating practical insights from industry leaders like HANI TECH.
1. Fundamentals of Steel Rolling Mills
UN laminoir d'acier employs compressive forces to reduce steel thickness or shape billets into finished products. The process occurs in two primary phases:
- Laminage à chaud: Conducted above recrystallization temperatures (typically 1100-1300°C)
- Laminage à froid: Performed at room temperature for enhanced surface finish
2. Composants clés des systèmes de laminoirs
HANI TECH solutions de laminoirs à chaud highlight these critical subsystems:
- Work rolls and backup rolls (forged alloy steel with 55-65 HRC hardness)
- CAG hydraulique (Contrôle automatique de la jauge) systèmes (±0.005mm precision)
- Temperature-controlled reheat furnaces (up to 1350°C capacity)
3. Paramètres techniques des laminoirs modernes
