Introduction to Roller Steel Hot Rolling Mills
El roller steel hot rolling mill is a cornerstone of industrial metalworking, transforming raw steel into precise shapes for construction, automotive, and machinery sectors. This process involves heating steel above its recrystallization temperature (typically 1100–1300°C) and passing it through rotating rolls to achieve desired thickness and structural integrity. HANI TECNOLOGÍA, a global leader in metallurgical equipment, provides state-of-the-art hot rolling mill systems that integrate automation and energy efficiency.
How a Roller Steel Hot Rolling Mill Works
In a roller steel hot rolling mill, the steel slab is reheated in a furnace and sequentially reduced in thickness by pairs of horizontally or vertically aligned rolls. Key components include:
- Work Rolls: Directly contact the steel, applying compressive force.
- Backup Rolls: Reinforce work rolls to prevent deflection.
- Mill Stand: Houses the roll assembly and drive mechanisms.
- Sistema de enfriamiento: Rapidly quenches steel to lock in mechanical properties.
HANI TECH’s mills feature hydraulic gap control (HGC) y profile automation, ensuring uniform product quality while minimizing material waste.
Industrial Applications of Hot Rolling Mills
Roller steel hot rolling mills produce a wide range of products:
- Structural Steel: vigas I, channels, and rails for construction.
- Automotive Plates: High-strength sheets for vehicle frames.
- Pipeline Tubes: Seamless pipes for oil and gas transportation.
HANI TECH’s hot rolling solutions are trusted by Tier-1 manufacturers for their ability to handle high-carbon steels, stainless steels, and specialty alloys.
Key Advantages of Modern Hot Rolling Mills
