А hot rolled steel mill is a cornerstone of modern metallurgy, Преобразование необработанной стали в универсальные продукты, используемые в строительстве, автомобильный, и производство. This article delves into the technology behind станы горячей прокатки, их эксплуатационные параметры, и инновации от мировых поставщиков, таких как HANI TECH.
What is a Hot Rolled Steel Mill?
А hot rolled steel mill processes steel slabs or billets at temperatures above 1,700°F (926°С), where the material becomes malleable. The process involves:
- Обогрев: Slabs are reheated in furnaces to achieve uniform plasticity.
- Rolling: High-pressure rollers reduce thickness and shape the steel.
- Cooling: Controlled cooling (НАПРИМЕР., laminar flow) ensures desired mechanical properties.
Compared to cold rolling, станы горячей прокатки offer higher productivity and lower costs for large-scale production.
Key Equipment in a Hot Rolled Steel Mill
HANI TECH, a leading manufacturer, provides integrated solutions for hot rolled steel mills, включая:
- Reheating Furnaces: Efficiently heat slabs with minimal scale formation.
- Черновая обработка & Finishing Mills: Multi-stand rollers for precise thickness control.
- Coilers: Wind hot-rolled strips into coils for storage and transport.
Their hot rolling mill equipment emphasizes energy efficiency and automation, reducing operational costs by up to 15%.
Technical Parameters of a Hot Rolled Steel Mill
Below are critical specifications for a typical hot rolled steel mill:
| Параметр | Диапазон значений | Единица |
