Get PriceIn practical furnace operation, refractory materials are not selected by name, but by material system, working temperature, corrosion environment, and mechanical load.
Below, refractory products are grouped by material category, with international brand names listed inside each category, showing how different names often refer to the same type of refractory material.
Different refractory product names and brand series such as
Vesuvius CastX, RHI CastCrete, Calderys HYCOR, HarbisonWalker Ultra-Low Iron Castables, Resco Rescocast, Plibrico Plicast, etc.,
all belong to the alumina-based refractory system.
Same Material Reality
These products are primarily differentiated by:
| Typical Grade Range | Common Alumina Content |
| Medium Duty | 45–60% Al₂O₃ |
| High Duty | 60–75% Al₂O₃ |
| Super Duty | 75–90% Al₂O₃ |
Kerui Refractory supplies equivalent alumina-based castables and bricks with customized chemistry and particle grading according to furnace conditions.
Product names such as
SEPR AZS-33 / 36 / 41, Corhart AZS, Corhart ZAC, etc.,
refer to fused cast AZS refractories used mainly in glass furnace linings.
Same Material Reality
AZS refractories are classified by zirconia (ZrO₂) content, not by brand.
| AZS Grade | Typical ZrO₂ Content | Typical Application Zone |
| AZS-33 | ~33% | Superstructure |
| AZS-36 | ~36% | Sidewalls |
| AZS-41 | 75–90% Al₂O₃ | Throat, hot spots |
Performance differences depend on:
Kerui Refractory provides customized fused-cast AZS blocks based on furnace position and corrosion severity.
Names such as
RHI MagChrome, MagCorund, Doloma series, SpinelCast, etc.,
all represent MgO-based or MgO–Al₂O₃ spinel refractories.
Same Material Reality
These materials are selected based on:
| Material Type | Typical Composition |
| Magnesia | MgO 85–98% |
| Spinel | Al₂O₃ + MgO |
Widely used in steel ladles, converters, and non-ferrous furnaces, these products are often customized for slag chemistry and thermal shock resistance.
Product names including
Morgan Plastimat, Vesuvius Plastic series, Resco Plastic, Dry Ramming Mix, etc.,
describe installation form, not material uniqueness.
Same Material Reality
All monolithic refractories are defined by:
| Type | Installation Method |
| Castable | Pouring / vibration |
| Plastic | Hand or pneumatic ramming |
| Ramming mix | Dry or semi-dry ramming |
Kerui Refractory adjusts flowability, setting time, and strength development according to on-site installation conditions.
Names such as
Morgan IFB, Calderys insulating castables, lightweight refractory bricks, etc.,
belong to the thermal insulation refractory system.
Same Material Reality
Key selection factors include:
| Density Range | Typical Use |
|---|---|
| 0.6–1.0 g/cm³ | Backup lining |
| 1.0–1.3 g/cm³ | Hot-face insulation |
International product names and brand series such as
Morgan Superwool / Kaowool, Unifrax Fiberfrax, RHI Ceratherm, Calderys Cerablanket, IBIDEN ceramic fiber, etc.,
all belong to the ceramic fiber insulation system, widely used for heat insulation, heat sealing, and thermal shock buffering.
Same Material Reality
Despite different branding, ceramic fiber products are classified mainly by:
Fiber chemistry (Alumina–Silica / AES / Polycrystalline)
Maximum service temperature
Form of supply
| Product Form | Typical Service Temperature |
|---|---|
| Ceramic fiber blanket | 1,260–1,430°C |
| Ceramic fiber board | 1,260–1,400°C |
| Ceramic fiber module | 1,260–1,430°C |
| Polycrystalline fiber | up to 1,600°C |
From a material perspective, fiber diameter, shot content, and fiber length distribution play a much larger role in performance than the product name itself.
Kerui Refractory supplies customized ceramic fiber solutions, including blankets, boards, modules, papers, and vacuum-formed shapes, optimized for:
International kiln furniture brands and product lines such as
Saint-Gobain Advancer, Kyocera silicon carbide setters, Morgan SuperSiC, RHI SiC kiln furniture, Nishimura cordierite-mullite systems, etc.,refer to load-bearing refractory components used inside kilns, not furnace linings.
Same Material Reality
Kiln furniture is classified mainly by material system and mechanical performance, including:
Material Type Typical Characteristics
Reaction-bonded SiC High strength, excellent thermal shock resistance
Sintered SiC High purity, superior oxidation resistance
Mullite Good creep resistance at high temperature
Cordierite-mullite Low thermal expansion, lightweight
Regardless of brand, kiln furniture performance depends on:
Kerui Refractory designs and manufactures custom kiln furniture, including beams, plates, setters, saggers, posts, and special shapes, based on kiln type and firing curve, not catalog numbers.
Regardless of brand or refractory material name, all products are application-driven and customizable.
To recommend or match any international refractory product, the following information is required:
Necessary Information
Optional but Highly Valuable
Based on this information, Kerui Refractory can provide equivalent or optimized refractory solutions, even when the original product specifications are unclear.
Different product names may look complex, but the material systems behind them are limited and well-defined.
By focusing on working conditions instead of brand labels, customers gain better control over performance, cost, and service life.
Keuri can customize various refractory materials according to different kiln conditions.
