Introduction to Steel Rolling Mill Plants
А steel rolling mill plant is a critical industrial facility that transforms raw steel into usable products through controlled deformation processes. These plants utilize specialized machinery, such as hot rolling mills и станы холодной прокатки, to produce sheets, plates, бары, and structural components. Modern facilities integrate advanced automation and precision control systems to meet stringent quality standards in industries like construction, автомобильный, and aerospace.
Core Components of a Steel Rolling Mill Plant
1. Hot Rolling Mill Systems
А стан горячей прокатки process involves heating steel billets above 1,100°C to improve malleability. Key equipment includes:
- Reheating furnaces for uniform temperature distribution
- Roughing stands for initial thickness reduction
- Finishing mills for final dimensional accuracy
HANI TECH’s hot rolling mill components feature wear-resistant alloys and smart temperature sensors, reducing downtime by 18% compared to conventional systems.
2. Cold Rolling Mill Technology
Cold rolling mills process steel at room temperature to achieve tighter tolerances (±0.01mm) and superior surface finishes. Critical subsystems include:
- Tension levelers for stress relief
- Electrolytic cleaning lines
- High-precision roll gap controllers
