High-Alumina Castables | Industrial furnaces, kilns, metal smelting | Refractoriness: 1500-1600°C (Industry Standard) ▲1580-1770°C (Our Base) ▲1770-1830°C (Our Advanced) Chemical resistance: Withstands 50+ exposures (ASTM D543) Powder form (ISO 3801: 285 GSM) | ▲ Superior temp resistance in Advanced tier Uniform particle size (reduces cracking) Easy installation via casting | Higher cost than fireclay bricks Requires curing time |
Fireclay Bricks | Glass kilns, low-temp industrial ovens | Refractoriness: 1200-1400°C Thermal shock resistance: Passes ASTM C648 (ΔT 200°C) | Cost-effective Easy to handle and cut High compressive strength (≥40 MPa) | Limited to lower-temperature applications Heavier than lightweight alternatives |
Insulating Castables | Thermal insulation in furnaces | Thermal conductivity: 0.15 W/m·K (ISO 8894) Low density: 1.2 g/cm³ (ASTM C20) | Energy-efficient (reduces heat loss) Lightweight for easier handling | Lower mechanical strength (not load-bearing) Lower max temp (≤1200°C) |
Chrome-Magnesia Refractories | Steelmaking, acidic slag environments | Refractoriness: 1750-1800°C Acidic slag resistance (ASTM C719) | Withstands acidic corrosion High-temperature stability in harsh conditions | High cost Requires specialized installation (expansion joints) |
Lightweight Insulating Firebricks | High-temp insulation with weight constraints | Density: 0.8-1.0 g/cm³ (ASTM C120) | Lightweight for easier handling Excellent thermal insulation (0.04 W/m·K) | Fragile (prone to mechanical damage) Lower load-bearing capacity |
Refractory Mortar | Sealing joints in refractory structures | Max temp: Matches adjacent material (e.g., 1600°C for alumina castables) Adhesion strength: ≥1.5 MPa (ASTM C110) | Ensures structural integrity Prevents gas/liquid leaks | Limited standalone use Requires precise mixing ratios |
