Overview
Castable refractory cement is a versatile material for forge construction and repairs, offering rapid installation, thermal stability up to 1,650°C (3,002°F), and resistance to thermal shock. Ideal for both hobbyist blacksmiths and industrial foundries, this guide explores its properties, application methods, and cost-effective procurement strategies—with insights into Kerui Refractory’s tailored solutions.
1. Key Properties & Advantages
1.1 Technical Specifications
Parameter | Kerui KR-FC80 | Industry Standard | Test Method |
---|---|---|---|
Max Service Temp | 1,650°C | 1,500–1,600°C | ASTM C113 |
Cold Crushing Strength | ≥60 MPa | 40–50 MPa | ASTM C133 |
Thermal Conductivity | 1.2 W/m·K | 1.5–2.0 W/m·K | ASTM C201 |
Setting Time | 2–4 hours | 3–6 hours | ASTM C191 |
Al₂O₃ Content | ≥80% | 50–70% | XRF Analysis |
Kerui’s KR-FC80 outperforms standard products with 20% higher thermal shock resistance (>30 cycles at ΔT 1,000°C).
1.2 Unique Benefits
- Rapid Curing: Achieve operational readiness in 24 hours vs. 48–72 hours for traditional bricks.
- Seamless Linings: Eliminate joints vulnerable to heat leakage.
- Custom Shapes: Mold complex forge geometries (e.g., parabolic hearths) effortlessly.
2. Step-by-Step Installation Guide
2.1 Material Preparation
- Mixing Ratio: 10–12% water by weight (6–7% for low-cement variants).
- Equipment: Use a paddle mixer for homogeneous consistency (avoid hand mixing).
2.2 Application Steps
- Surface Prep: Clean metal forge shell; install ceramic fiber insulation layer (optional).
- Formwork Setup: Build wooden/metal molds for desired forge shape.
- Pouring: Fill molds in layers ≤100mm, vibrating each layer for >90% compaction.
- Curing: Maintain 15–25°C for 24 hours; gradual heat-up (50°C/hour) to 600°C.
2.3 Maintenance Best Practices
- Crack Repair: Use Kerui’s KR-PC15 Patch Cement for gaps ≤5mm.
- Annual Inspection: Check for erosion >10% thickness in burner zones.
3. Cost Analysis & Procurement Tips
3.1 Pricing Overview
Product Grade | Price Range (FOB) | Min Order Quantity |
---|---|---|
Standard (Al₂O₃ 50–70%) | $410–550/ton | 1 tons |
Premium (Al₂O₃ ≥80%) | $600–1,050/ton | 1 tons |
Note: Bulk orders (≥20 tons) qualify for 8–12% discounts.
3.2 Supplier Selection Criteria
- Certifications: Verify ISO 9001 and ASTM compliance.
- Logistics: Prioritize suppliers with DDP shipping (duties prepaid).
- Samples: Request 2-5kg test batches for small-scale trials.
4. Kerui’s Innovative Solutions
4.1 Product Highlights
- KR-FC80 Forge Cement:
