Special Phosphate Composite Refractory Brick
Phosphate Refractory Bricks I. Main Product Types Standard Phosphate Bricks (P Series): Composition: phosphate-bonded high-alumina bauxite (Al₂O₃ ≥ 65%); Apparent Porosity: 18–22%; Load-Softening Temperature: ≥1300°C. Phosphate Wear-Resistant Bricks (PA Series): Reinforcement Process: bonded with aluminum phosphate solution; Abrasion Index: ≤6 cm³ (ASTM C704); Compressive Strength: ≥50 MPa; Steel-Fiber-Reinforced Type (New Model 2025): Incorporation of 3–5% stainless steel fibers increases thermal-shock resistance to 80 cycles (water cooling at 1100°C) and flexural strength by 120%. II. Intelligent Production Processes Raw-Material Preprocessing System: Grading and crushing of bauxite clinker (optimized particle-size distribution of 1–3 mm); Intelligent formulation of phosphate solution (concentration 42.5–50%); Key Process Control: A [Mixing] → B (maturation for 24 hours at 25°C); B → C [High-Pressure Molding]; C → D (drying at 110°C for 48 hours); D → E [Heat Treatment at 400–600°C]. Green Manufacturing Technology: Low-Temperature Firing (reduces energy consumption by 35% compared with conventional processes); Waste Brick Recycling Rate Reaches 45%. III. Typical Application Scenarios Application Fields and Service Locations Technical Benefits Cement Industry Rotary Kiln Transition Zone: Service Life Extended to 18 Months Metallurgical Industry Blast Furnace Hearth: Resistance to Molten Iron Erosion Improved by 50% Environmental Protection Projects Waste Incinerator: Enhanced Resistance to Chloride Corrosion Chemical Equipment Sulfuric Acid Reactor Lining: Maintenance Interval Extended by a Factor of Three IV. Performance Advantages Compared with Traditional Refractories Thermal-Shock Stability: 50 cycles vs. 10 cycles for High-Alumina Bricks; Wear Resistance: 3.5 Times That of Clay Bricks; Medium-Temperature Strength: At 1000°C, Strength Retention Rate ≥90%; Economic Analysis: Production Cost: 60–70% Lower Than Zirconia-Corundum Bricks; Overall Benefit: Unit Usage Cost Reduced by 45%. V. Physicochemical Specifications (GB/T 2026-P) 1. Basic Properties: Bulk Density: 2.4–2.6 g/cm³; Compressive Strength: ≥35 MPa (PA Type: ≥50 MPa); High-Temperature Characteristics: Linear Change After Reheating: +0.1 to +0.3% (at 1200°C); Alkali-Erosion Resistance: Weight Gain Due to K₂O ≤1.5% (at 1000°C for 50 hours); Special Indicators: Thermal-Shock Resistance: ≥50 Cycles (Steel-Fiber-Reinforced Type); Thermal Conductivity: 1.1 W/(m·K) (at 800°C).
