Buy high quality low price STEEL LADLE BRICKS at 70 - 85 INR / Kg at Wedge India. Steel Ladle Bricks are refractory bricks specifically engineered to line the interior of steel ladles, which are vessels used to transport and treat molten steel in steel plants. These bricks must withstand extreme temperatures, slag corrosion, and thermal shock, making them critical for safe and efficient steel production.
Types of Steel Ladle Bricks:
Steel ladle bricks are selected based on ladle design, steel type, and slag chemistry. Here are the most common types:
| Brick Type | Main Components | Ideal For |
|---|---|---|
| Magnesia-Carbon (MgO-C) | Magnesia + Graphite | High-performance ladles with basic slags |
| Alumina-Carbon (Al₂O₃-C) | Alumina + Graphite | Intermediate temp ladles or acidic slags |
| High Alumina Bricks | 70–90% Al₂O₃ | Preheating zones or working linings |
| Magnesia-Chrome Bricks | MgO + Cr₂O₃ | Corrosive environments (less used today) |
| Dolomite Bricks | CaO + MgO | Cost-effective option for basic slags |
| Spinel Bricks | Alumina + MgO (sintered spinel) | Slag lines with moderate wear |
Key Properties Required in Ladle Bricks:
| Property | Description |
|---|---|
| High Refractoriness | Must withstand >1700°C |
| Slag Resistance | Especially to basic or acidic slags |
| Thermal Shock Resistance | To prevent spalling during tapping or casting |
| Mechanical Strength | Must resist erosion from steel flow and stirring |
| Oxidation Resistance | Especially for carbon-containing bricks |
Where Ladle Bricks Are Used:
| Ladle Zone | Recommended Bricks |
|---|---|
| Working Lining | MgO-C, Al₂O₃-C, high alumina |
| Slag Line | Spinel, MgO-C, impregnated dolomite |
| Bottom | High strength Al₂O₃-C or MgO bricks |
| Impact Zone | Ultra-high strength MgO-C bricks |
| Safety Lining | Fireclay or high alumina bricks |
Advantages of Using Quality Ladle Bricks:
Longer ladle campaign life
Reduced steel contamination
Lower thermal loss and better energy efficiency
Fewer shutdowns for relining
