Rongsheng Refractory Company
High-performance unshaped refractory materials engineered for durability, thermal stability, and energy efficiency. Trusted by industries worldwide for kilns, furnaces, boilers, and cement production systems.
Visit Official WebsiteMonolithic refractories, also known as unshaped refractory materials, are a major category of heat-resistant materials used in industrial thermal equipment. Unlike traditional firebricks, these materials are supplied in bulk form—without a fixed shape—and are installed directly into furnaces, kilns, and boilers as seamless linings.
Composed of refractory aggregates, powders, binding agents, and additives in precise grain size distributions, monolithic refractories are applied via casting, ramming, gunning, or coating methods. After installation and curing, they form a dense, durable, and joint-free lining that enhances structural integrity and thermal performance.
Lower thermal conductivity reduces heat loss and improves energy savings.
Simplified manufacturing and installation reduce labor and material costs.
Excellent wear, slag, and thermal shock resistance ensure long service life.
Hydraulically bonded, high-strength material ideal for kiln linings, boiler walls, and industrial furnaces. Offers excellent thermal stability and abrasion resistance.
Advanced formulation with reduced cement content for higher density, strength, and thermal shock resistance. Ideal for heating and rolling furnaces.
Low-density, insulating castable with excellent thermal insulation properties. Reduces heat loss and structural load in large industrial systems.
Unbonded granular mix designed for vibration or pneumatic ramming. Used in induction furnaces and high-temperature linings requiring excellent sintering behavior.
Specialized basic ramming mix for steel and non-ferrous metal melting furnaces. Offers superior slag resistance and chemical stability.
Acidic ramming material with high SiO2 content. Ideal for glass tank furnaces and applications requiring resistance to acidic slags.
High-adhesion mortar for bonding refractory bricks and patching joints. Ensures seamless integration with monolithic and shaped refractories.
Moldable, non-fired refractory ideal for boiler repairs and complex geometries. Retains strength after drying and firing.
Protective spray or brush-on layer that enhances surface durability, reduces oxidation, and improves heat reflection in furnace linings.
Graphite-based ramming mix for blast furnaces and tapholes. Offers excellent thermal conductivity and resistance to molten metal and slag.
Low thermal conductivity reduces fuel consumption and operational costs.
Monolithic application eliminates joints, reducing leakage and erosion risks.
No pre-shaping required—install directly on-site with minimal downtime.
Tailored formulations for specific temperature, chemical, and mechanical demands.

Castable refractory is poured or vibrated into place and sets hydraulically, while plastic refractory is moldable and requires drying and firing. Castables are used for large linings; plastics are ideal for repairs and complex shapes.
Yes, high-alumina and low-cement castables are commonly used in rotary and precalciner kilns due to their high strength, abrasion resistance, and thermal stability.
Yes, Rongsheng provides customized monolithic refractory solutions based on temperature, chemical exposure, and mechanical stress requirements.
Dry ramming mass is compacted using pneumatic or mechanical rammers without water. It sinters in-situ during initial heating to form a dense, durable lining.
