In steel and metal production, cooling is critical for controlling temperatures during rolling and continuous casting operations. Precision spray systems ensure uniform cooling, minimize thermal stress, improve product quality, and extend equipment life—supporting efficient and reliable mill performance.
Key Benefits
- Delivers precise cooling during rolling and casting
- Reduces thermal cracking and surface defects
- Improves metallurgical properties and consistency
- Extends equipment service life through controlled cooling
- Optimizes water usage while maintaining cooling efficiency
Table 1: Cooling Requirements in Rolling Mills
| Stage | Target Temp (°C) | Spray Type | Key Purpose |
|---|---|---|---|
| Roughing | 950–1050 | Flat fan, high flow | Reduce scale, control heat |
| Intermediate | 850–950 | Fine mist, medium impact | Surface conditioning |
| Finishing | 650–750 | Uniform spray headers | Shape control, quality finish |
Table 2: Continuous Casting Spray Zones
| Zone | Nozzle Type | Spray Angle | Cooling Role |
|---|---|---|---|
| Mold Exit | Air–water mist | 15°–30° | Initial shell solidification |
| Secondary | Flat fan | 30°–60° | Uniform shell thickening |
| Final Zone | Full cone | 60°–90° | Final cooling before cutting |
Table 3: Cooling Efficiency by Spray Pressure
| Spray Pressure (bar) | Droplet Size (µm) | Heat Transfer Efficiency | Scale Reduction |
|---|---|---|---|
| 3–5 | 250–300 | Moderate | Low |
| 6–10 | 150–200 | High | Moderate |
| 10–15 | 80–120 | Very High | High |
