Steel rolling equipment is the backbone of modern metallurgy, transforming raw metal into precise shapes for construction, автомобильный, и обрабатывающей промышленности. This article delves into the mechanics, типы, and critical parameters of стальное прокатное оборудование, with insights from industry leaders like HANI TECH и HAN Metallurgy.
1. What is Steel Rolling Equipment?
Steel rolling equipment refers to machinery used to reduce the thickness or change the cross-section of metal billets, плиты, or blooms through compressive forces. The process involves:
- Горячая прокатка: Performed above recrystallization temperatures (НАПРИМЕР., 1100°C for carbon steel).
- Холодная прокатка: Conducted at room temperature for improved surface finish.
- Tandem mills: Multiple stands for continuous processing.
2. Key Components of Rolling Mills
Современный steel rolling systems integrate:
- Work rolls: Directly contact the metal (material: tungsten carbide or forged steel).
- Backup rolls: Support work rolls to prevent deflection.
- Rolling mill stands: Housing for roll assemblies (НАПРИМЕР., 2-high, 4-high, or cluster mills).
- Descaling systems: High-pressure water jets to remove oxide layers.
3. Technical Parameters of Steel Rolling Equipment
Below are critical specifications for industrial-grade прокатные станы:
| Параметр | Стан горячей прокатки | Стан холодной прокатки | Единица |
