ال hot rolled steel mill is a cornerstone of modern metallurgy, transforming raw steel into versatile products used in construction, السيارات, والتصنيع. This article delves into the technology behind مصانع الدرفلة الساخنة, their operational parameters, and innovations from global suppliers like HANI TECH.
What is a Hot Rolled Steel Mill?
أ hot rolled steel mill processes steel slabs or billets at temperatures above 1,700°F (926درجة مئوية), where the material becomes malleable. The process involves:
- Heating: Slabs are reheated in furnaces to achieve uniform plasticity.
- Rolling: High-pressure rollers reduce thickness and shape the steel.
- Cooling: Controlled cooling (على سبيل المثال, laminar flow) ensures desired mechanical properties.
Compared to cold rolling, مصانع الدرفلة الساخنة offer higher productivity and lower costs for large-scale production.
