El hot rolled steel mill es una piedra angular de la metalurgia moderna, Transformar el acero en bruto en productos versátiles utilizados en la construcción., automotor, y fabricación. This article delves into the technology behind molinos calientes, sus parámetros operativos, e innovaciones de proveedores globales como HANI TECH.
¿Qué es una acería laminada en caliente??
A hot rolled steel mill processes steel slabs or billets at temperatures above 1,700°F (926°C), where the material becomes malleable. El proceso implica:
- Calefacción: Slabs are reheated in furnaces to achieve uniform plasticity.
- Laminación: High-pressure rollers reduce thickness and shape the steel.
- Enfriamiento: Controlled cooling (p.ej., laminar flow) ensures desired mechanical properties.
Comparado con el laminado en frío, molinos calientes offer higher productivity and lower costs for large-scale production.
