- Scrap Steel Integration: Recycled steel scrap is carefully sorted and prepared, contributing to sustainable production practices.
- Quality Control: Raw materials undergo rigorous testing to verify chemical composition and physical properties.
Hot Rolling Process
The hot rolling stage involves:
- Heating: Steel slabs are heated to approximately 1200°C
- Rolling: Multiple passes through rolling mills reduce thickness
- Cooling: Controlled cooling determines final mechanical properties
- Coiling: Finished products are coiled for transportation and storage
Cold Rolling and Finishing
- Cold Rolling: Further thickness reduction and surface improvement through room-temperature processing.
- Annealing: Heat treatment to optimize mechanical properties and formability.
- Surface Treatment: Application of coatings, galvanizing, or other protective finishes.
- Quality Inspection: Final testing to ensure compliance with specifications and standards.
Quality Standards and Specifications
Flat-rolled steel products must meet stringent industry standards including:
- ASTM (American Society for Testing and Materials) specifications
- ISO (International Organization for Standardization) requirements
- Industry-specific standards for automotive, construction, and appliance applications
