| Parameter | Requirement |
|---|---|
| Mold Preheating Temperature | ≥150℃ |
| Mold Material | Mainly cast iron, aluminum alloy cavity can be anodized |
| Coating Requirement | Spray refractory coating to adjust cooling rate |
| Casting Weight Limitation | Not too large |
| Casting Shape | Mainly simple shapes |
| Parameter | Range |
|---|---|
| Annual Production Capacity | Slab: 2-2.5 million t/year Bloom: 0.8-1 million t/year Billet: 0.6-0.8 million t/year |
| Operating Rate | 80-90% |
| Casting Speed | Slab: 1.2-1.8 m/min (max 3.0) Billet: 2.5-3.5 m/min |
| Sequence Casting | Average 4-6 heats, max 329 heats |
| Radius | 11-17 m (max 18.5 m) |
| Parameter | Typical Range |
|---|---|
| Ingot Weight | 8-20 t |
| Height/Width Ratio | 2.5-3.5 |
| Taper | 0.8-4.2% |
| Wall Thickness | 50-160 mm |
| Mold/Ingot Weight Ratio | 0.8-1.2 |
| Corner Radius | 8-15% of diameter |
Taper Calculation Formula:
Square Section: Taper = (D₁ - D₂) / H × 100%
Round Section: Taper = (R₁ - R₂) / H × 100%
D₁ and D₂ are the lengths of the top and bottom edges, R₁ and R₂ are the radii of the top and bottom edges, and H is the height of the ingot
| Project | Requirement |
