Le steel rebar rolling mill is a critical component in modern metallurgy, transforming raw billets into high-strength reinforcement bars used in construction. Cet article plonge dans les aspects techniques, paramètres opérationnels, and innovative solutions offered by manufacturers like Hani Tech, a global leader in rolling mill technology.
1. What is a Steel Rebar Rolling Mill?
UN steel rebar rolling mill is a specialized facility that processes steel billets into reinforced bars (barres d'armature) through a series of rolling stands. Le processus implique le chauffage, brouillage, roulement intermédiaire, and finishing to achieve the desired diameter and mechanical properties. L'équipement clé comprend:
- Four de réchauffage
- Broyeur d'ébauche
- Broyeur intermédiaire
- Moulin de finition
- Cooling bed
- Shearing and bundling machines
