High-Temperature Industrial Processing Industry
Application:
Aluminum silicate ceramic provides stable high-temperature insulation for heat-treatment furnaces, tunnel kilns and industrial heating systems, helping maintain uniform thermal profiles and reduce energy loss.
🧩 Key Advantages:
- Aluminum silicate ceramic lowers furnace shell temperature by 25–45°C, improving thermal efficiency and reducing energy loss in continuous heat-treatment systems.
- Its controlled linear shrinkage—typically ≤1.0% after 24 h at 1100°C—keeps insulation assemblies stable during repeated heating and cooling cycles.
- With a low thermal mass and thermal conductivity of 0.16–0.21 W/m·K at 800°C, it enables shorter heat-up times and quicker cycle turnover for industrial furnaces.
🔹Problem Solved:
A U.S. heat-treatment furnace OEM previously used dense firebrick insulation, causing high heat-up time and shell temperatures exceeding 80°C. After upgrading to aluminum silicate ceramic panels, shell temperature was reduced by 38°C, while heat-up time shortened by 12–15% across multiple batches. This improvement raised throughput consistency, lowered energy consumption by an estimated 7–10%, and reduced operator-area thermal exposure—allowing the plant to maintain continuous 24/7 furnace operation with fewer thermal-related maintenance stops.
Metallurgy & Metal Casting Industry
Application:
Used for pouring cups, filter boxes, launder systems and molten-metal contact parts, aluminum silicate ceramic delivers clean metal flow, non-wetting behavior and consistent thermal stability in casting operations.
🧩 Key Advantages:
- Aluminum silicate ceramic maintains ≤0.5% metal adhesion after repeated aluminum contact, ensuring cleaner flow in launder and filter systems.
- Dimensional change remains ≤0.8% at 1200°C, preventing deformation in pouring cups and filter boxes during continuous casting.
- Its thermal conductivity of 0.17–0.23 W/m·K at 900°C minimizes heat drop in launder sections, improving temperature retention during transfer.
🔹Problem Solved:
A European aluminum foundry struggled with metal chilling in a 4-meter launder, causing flow turbulence and 3–4% reject rates in casting. After switching to aluminum silicate ceramic launder liners, temperature drop decreased by 18–22°C, metal flow stabilized, and casting defects dropped to below 1% within two weeks. The foundry reduced re-melting energy usage by 6–8% and extended liner replacement intervals from 3 months to nearly 7 months.
Glass, Ceramic & Building Materials Industry
Application:
Aluminum silicate ceramic supports annealing kilns, sintering kilns and roller kilns with lightweight, efficient insulation that improves temperature uniformity and long-term furnace performance.
🧩 Key Advantages:
- Aluminum silicate ceramic reduces heat leakage by 12–18%, helping maintain uniform temperature profiles in annealing and sintering kilns.
- Its volumetric heat capacity is 35–45% lower than dense refractory, enabling quicker heat-up and cooldown cycles.
- Retains ≥70% flexural strength at 1000°C, supporting stable kiln insulation structures over long production runs.
🔹Problem Solved:
- A glass-processing plant faced uneven thermal zones in an annealing kiln, causing optical distortion and a 5–7% defect rate. Aluminum silicate insulation panels reduced end-wall heat loss by 15%, resulting in more uniform thermal gradients. Product distortion fell below 2%, kiln cycle time improved by 8%, and maintenance inspections were reduced from monthly to quarterly due to improved lining stability.
