Low Cement Castable Corrosion Resistant
,Grey Low Cement Castable
Our LDSLC Series Low Cement Castable is engineered for applications demanding exceptional strength, density, and corrosion resistance in the critical mid-to-high temperature range. By utilizing low-calcium aluminate cement (typically <3% CaO content) as a binder and optimizing the particle size distribution, this castable achieves a uniform, low-porosity microstructure. This advanced formulation results in outstanding hot strength, excellent volume stability, and superior resistance to slag penetration and abrasion, making it a top-tier choice for severe service conditions.

- 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.
- Optimized Density & Low Porosity: Achieves a dense, uniform structure that acts as a robust barrier against corrosive slag and abrasive materials.
- Enhanced Corrosion & Abrasion Resistance: The impermeable matrix significantly reduces infiltration by molten slags and fluxes, while the high density resists wear.
- High Refractoriness & Volume Stability: Maintains dimensional stability and structural integrity under prolonged exposure to high temperatures.
- Engineered for Severe Environments: Specifically developed to withstand the combined chemical, thermal, and mechanical stresses in modern intensive processes.
This castable is the material of choice for critical linings where standard castables may fail due to slag attack, abrasion, or mid-temperature strength loss:
- Cement & Lime Industry: Transition zones, burning zones, and inlet ducts of rotary kilns; preheater cyclones.
- Steel Industry: Ladle well blocks, tundish impact pads, slag lines, and refining vessel linings.
- Non-Ferrous Metals: Furnace linings in copper, lead, and zinc smelting.
- Waste Incineration: High-wear areas exposed to aggressive slags and thermal cycling.
- Petrochemical: High-temperature reactor linings subject to corrosive atmospheres.
Choosing Low Cement Castable is an investment in process reliability and extended campaign life. Its engineered chemistry addresses the fundamental weaknesses of traditional castables, providing a predictable, high-performance lining that reduces maintenance frequency and protects against costly unscheduled downtime in your most valuable thermal assets.
