Refractory castable is the most mainstream type of monolithic refractories. It is prepared by mixing refractory aggregates, powders, binders and additives in a specified ratio. After mixing with water (or liquid), it is cast and vibrated to form, then cured and baked to form an integral furnace lining.
II. Core Characteristics
Good integrity: No brick joints; air tightness, erosion resistance and penetration resistance are far better than brick masonry.
Flexible construction: Can be cast into any shape, suitable for complex structures, repair and integral lining.
Complete product range: Covers low temperature to ultra-high temperature, wear resistance, slag resistance and thermal insulation.
Short construction period: Fast on-site installation, ideal for maintenance and emergency repair.
High strength: Stable medium and high temperature strength, adjustable thermal shock resistance.III. Classification
Classification by Binder Classification by Material / Chemical Composition Cement-bonded castable (Most commonly used)
Binded by aluminate cement (high alumina cement)
Typical products: Low cement castable, ultra-low cement castable, ordinary cement castable
Advantages: Easy construction, high strength, moderate cost
Applications: Ladle, heating furnace, rotary kiln, blast furnace trough, etcFireclay / High alumina castable
Al₂O₃: 40%~80%
General-purpose, service temperature 1300~1500℃
Applications: Heating furnaces, flues, hot air ducts, general kilnsWater glass-bonded castable
Good acid resistance, moderate high temperature strength
Applications: Chimneys, flues, acid working conditionsCorundum castable
Al₂O₃ ≥ 90%, high-purity corundum aggregateAl₂O₃≥90% High temperature resistance, strong slag resistance, good wear resistance
Applications: Ladle walls, slag line, burners, gasifiersPhosphoric acid / phosphate-bonded castable
Extremely high medium and high temperature strength, excellent wear resistance
Applications: Wear-resistant linings, burners, impact zonesMagnesia / Magnesia-alumina spinel castable
Basic material, extremely strong alkaline slag resistance
Applications: Ladle slag line, converter repair, cement kiln burning zoneSol-bonded castable (High performance)
Ultra-low impurities, excellent high temperature stability
Applications: Clean steel production, glass furnace, high-end furnace liningsLightweight thermal insulation castable
Porous structure, low thermal conductivity Applications: Back insulation, insulation layer, not in direct contact with molten slag
Wear-resistant castable
High density, high hardness
Applications: Iron trough, launder, coal powder pipeline, cyclone cylinderIV. Typical Applications (Full coverage in metallurgy /building materials /chemical industry)
Iron & steel: Ladle, tundish, iron trough, slag trough, heating furnace, walking beam fur那测
Cement: Preheater, calciner, cooler, kiln inlet
Petrochemical / Coal chemical: Gasifier, cracking furnace, heating furnace tube lining
Waste incineration: Incinerator, flue
Industrial furnaces: Heat treatment furnace, soaking furnace, chimney liningV. Key Performance Indicators (Essential for Bidding Documents)
- Refractoriness
- Cold modulus of rupture / Cold compressive strength
- Permanent linear change on firing
- Apparent porosity / Bulk density
- Thermal conductivity (for insulating castable
