Low Cement Refractory Castable MAX Service Temp 1800℃ High Temperature Casting Refractory Materials For Industrial Furnace
Low Cement Castable (LCC) is an advanced refractory material characterized by its significantly reduced content of calcium aluminate cement—typically with a CaO level below 3%. This deliberate formulation minimizes the formation of low-temperature calcium-aluminate phases, which traditionally weaken conventional castables in the intermediate temperature range (approximately 800°C to 1200°C). Consequently, LCCs maintain excellent strength and structural stability from the mid-temperature zone up to their maximum service temperature, avoiding the notable strength trough often seen in traditional cement-bonded refractories.
The low cement content is compensated by the precise incorporation of ultra-fine powders, such as reactive alumina and silica fume, along with specialized dispersing agents. This results in a dense, uniform microstructure with exceptionally low porosity after proper installation and curing. These microstructural qualities directly translate to superior performance: high refractoriness, outstanding resistance to chemical corrosion from slags and fluxes, and enhanced resistance to mechanical abrasion and thermal shock.
Due to these properties, Low Cement Castables are extensively employed in demanding applications across steel, cement, and petrochemical industries. They are commonly found in linings for ladles, tundishes, blast furnace troughs, and other high-wear zones where durability, thermal stability, and longevity are critical. The combination of optimized binder technology and a refined particle size distribution makes LCCs a cornerstone material for modern, high-efficiency industrial thermal processes.

Advantages:
1.Optimized Density & Low Porosity: Achieves a dense, uniform structure that acts as a robust barrier against corrosive slag and abrasive materials.
2.High Refractoriness & Volume Stability: Maintains dimensional stability and structural integrity under prolonged exposure to high temperatures.
3.Exceptional Mid-Temperature Strength: The low CaO content fundamentally eliminates the traditional strength dip in the 800-1200°C range, providing consistent and high mechanical performance throughout the heating profile.
4.Engineered for Severe Environments: Specifically developed to withstand the combined chemical, thermal, and mechanical stresses in modern intensive processes.
Application:
1.Glass & Ceramic Industry – Kilns and Industrial Furnaces
2.Steel Industry – Electric Arc Furnace, Converter, Ladle Linings
3.General Industrial Furnaces – Thermal-resistant linings and maintenance works
4.Cement Industry – Rotary Kiln Lining, High-Temperature Sections
