А steel rolling mill line is the backbone of modern metalworking, transforming raw steel into precise shapes like sheets, бары, и катушки. This article delves into the intricacies of rolling mill technology, highlighting critical equipment, process flows, and innovations from industry leaders like HANI TECH.
1. What Is a Steel Rolling Mill Line?
А steel rolling mill line comprises a series of machines that reduce steel thickness or alter cross-sections through controlled compression. The process enhances mechanical properties while achieving dimensional accuracy. Ключевые этапы включают в себя:
- Обогрев: Reheating furnaces bring billets to 1,100–1,300°C for plasticity.
- Черновая обработка: Initial reduction via roughing mills.
- Отделка: Precision shaping in tandem or reversing mills.
- Cooling & Coiling: Controlled cooling on run-out tables before coiling.
