Introduction to Steel Rolling Mill Plants
A steel rolling mill plant is a critical industrial facility that transforms raw steel into usable products through controlled deformation processes. Estas plantas utilizan maquinaria especializada., como molinos calientes y laminadores en frío, para producir hojas, platos, verja, y componentes estructurales. Modern facilities integrate advanced automation and precision control systems to meet stringent quality standards in industries like construction, automotor, y aeroespacial.
Core Components of a Steel Rolling Mill Plant
1. Hot Rolling Mill Systems
El laminador en caliente process involves heating steel billets above 1,100°C to improve malleability. El equipo clave incluye:
- Hornos de recalentamiento for uniform temperature distribution
- Roughing stands for initial thickness reduction
- Finishing mills for final dimensional accuracy
HANI TECH hot rolling mill components feature wear-resistant alloys and smart temperature sensors, reduciendo el tiempo de inactividad mediante 18% en comparación con los sistemas convencionales.
2. Cold Rolling Mill Technology
Cold rolling mills process steel at room temperature to achieve tighter tolerances (±0.01mm) and superior surface finishes. Los subsistemas críticos incluyen:
- Tension levelers for stress relief
- Electrolytic cleaning lines
- High-precision roll gap controllers
