Steel rebar mills are the backbone of modern construction, producing reinforced bars that provide tensile strength to concrete structures. These mills utilize advanced rolling technology to transform billets into high-quality rebars with precise dimensions and mechanical properties. In this article, we delve into the intricacies of steel rebar mills, their operational parameters, and the cutting-edge solutions offered by industry leaders like HANI TECH.
1. The Role of Steel Rebar Mills in Construction
Steel rebar mills specialize in the production of hot-rolled ribbed bars (HRB), which are essential for reinforcing concrete in infrastructure projects. The process involves heating billets to 1,100–1,250°C in a reheating furnace, followed by multi-pass rolling in roughing, intermediate, and finishing stands. Key equipment includes:
- Reheating furnaces
- Roughing mills
- Finishing mills
- Cooling beds
- Shearing machines
2. Key Parameters of Steel Rebar Mills
Below is a detailed table showcasing critical technical parameters for modern steel rebar mills:
| Parameter | Value Range | Unit |
|---|---|---|
| Billet Size | 120×120 – 160×160 | mm |
| Rolling Speed | 12 – 40 | m/s |
| Annual Capacity | 300,000 – 1,000,000 | tons/year |
| Finished Rebar Diameter | 8 – 40 | mm |
| Rolling Temperature | 950 – 1,100 | °C |
| Motor Power (Roughing Mill) | 1,500 – 3,500 | kW |
| Cooling Bed Length | 60 – 120 | m |
