With decades of experience in thermal engineering, ACS Thermal Engineering is your trusted partner for the design, installation, and maintenance of castable refractory linings across various industries.

What are Castable Refractory Lining Systems?
Castable refractory materials are a type of heat-resistant, monolithic (non-brick) refractory material composed of refractory aggregates, binders, and additives. These materials are mixed with water and then cast or poured into place to form a durable, seamless refractory lining. Once set and dried, castable refractory linings can withstand extremely high temperatures and provide excellent protection against thermal stress, chemical attack, abrasion, and mechanical wear.

Castable refractory lining systems are highly versatile, allowing for custom molding and shaping to fit the specific design of your industrial equipment. They are used in applications where traditional brickwork may not be feasible or where complex geometries require a monolithic solution.

Benefits of Castable Refractory Lining Systems
High-Temperature Resistance: Castable refractory linings are designed to withstand temperatures ranging from 1000°C (1832°F) to over 1800°C (3272°F), depending on the material formulation.
Monolithic Construction: Unlike brick linings, castable refractory systems create a seamless, joint-free structure that eliminates weak points and minimizes the risk of cracking and spalling.
Custom Fit for Complex Shapes: Castable refractory can be easily poured or troweled into place, allowing for precise installation in irregular or complex-shaped furnaces, kilns, boilers, and other industrial equipment.
Excellent Mechanical Strength: Castable refractory materials provide outstanding resistance to mechanical wear and impact, making them ideal for environments subject to abrasion, mechanical stress, and frequent thermal cycling.
Thermal Shock Resistance: These materials offer excellent thermal shock resistance, which helps maintain the structural integrity of the lining even under rapid temperature changes.
Chemical Resistance: Castable refractory linings resist chemical attack from slag, molten metals, gases, and corrosive substances, making them ideal for use in harsh industrial environments.
Energy Efficiency: Castable refractory materials offer low thermal conductivity, helping to minimize heat loss, reduce fuel consumption, and improve overall energy efficiency.
Key Applications of Castable Refractory Lining Systems
Castable refractory lining systems are widely used in a variety of high-temperature industrial processes. At ACS Thermal Engineering, we provide customized castable refractory solutions for a broad range of applications, including:

Steel and Metallurgical Furnaces: Castable refractories are commonly used in electric arc furnaces (EAFs), ladles, tundishes, and blast furnaces, where their high thermal resistance and mechanical durability are essential for withstanding extreme heat and molten metal exposure.
Cement and Lime Kilns: In rotary kilns, preheater towers, and other cement and lime processing equipment, castable refractory linings provide excellent thermal insulation and protect against chemical erosion and abrasion.
Petrochemical and Refining: Castable refractories are used in petrochemical reformers, cracking units, and catalytic reactors, where they resist high temperatures, thermal cycling, and chemical attack from process gases and hydrocarbons.
Power Generation: Castable refractory linings are essential in boilers, gasifiers, incinerators, and flue gas systems in power plants, helping to enhance energy efficiency and withstand the rigors of thermal shock and erosion.
Glass and Ceramic Manufacturing: Castable refractory linings provide insulation and protection in glass melting furnaces, ceramic kilns, and related equipment, ensuring uniform heat distribution and structural integrity under high temperatures.
Foundries and Casting Equipment: Castable refractory is used to line ladles, tundishes, and casting molds in foundries, offering resistance to molten metal corrosion and mechanical wear.
