А steel rebar rolling mill is a critical component in modern metallurgy, transforming raw billets into high-strength reinforcement bars used in construction. This article delves into the technical aspects, эксплуатационные параметры, and innovative solutions offered by manufacturers like HANI TECH, a global leader in rolling mill technology.
1. What is a Steel Rebar Rolling Mill?
А steel rebar rolling mill is a specialized facility that processes steel billets into reinforced bars (арматура) through a series of rolling stands. The process involves heating, roughing, intermediate rolling, and finishing to achieve the desired diameter and mechanical properties. Ключевое оборудование включает в себя:
- Нагревательная печь
- Черновой стан
- Промежуточная мельница
- Чистовой стан
- Охлаждающая кровать
- Shearing and bundling machines
