Product Description Product DescriptionThe High Purity Sillimanite Based Andalusite Brick is a premium-grade refractory material specially developed for steel industry ladle, tundish, and furnace linings.It is manufactured from selected natural andalusite and sillimanite minerals, fired at high temperatures to form a mullite-bonded structure with excellent thermal shock resistance, corrosion resistance, and high strength.This brick is widely used in steel ladles, tundish linings, reheating furnaces, and industrial kilns due to its outstanding resistance to slag corrosion and deformation at high temperatures.Features Excellent Thermal Shock Resistance - Maintains structural integrity under frequent heating and cooling cycles.High Refractoriness Under Load (RUL) - Stable at temperatures exceeding 1700°C, ideal for long working conditions.Strong Corrosion and Erosion Resistance - Resists slag and molten metal attack, prolonging furnace lining life.High Mechanical Strength and Density - Provides dimensional stability and reduces cracking during service.Energy Saving & Long Service Life - Improved heat retention reduces energy loss and maintenance costs.Customization Available - Tailor-made shapes and sizes according to customer drawings.ApplicationSteel Industry:Ladle and tundish liningsReheating furnace roof and wallHot metal transfer and pouring zonesCement and Glass Industry:Burner zones and transition areasGlass kiln upper structure and regenerator checkerNon-ferrous Metal Industry:Aluminum melting and holding furnacesCopper smelting equipment linings BrandProperties60% Alumina Clay Brick36%Alumina Clay BrickApparent Porosity (%)≤24≤22Bulk Density (g/cm3)≥2.35≥2.17Cold Crushing Strength (MPa)≥40≥30Thermal Linear Expansion @ 1,000oC (%)0.60.6Permanent Linear Change@ 1350oC x 2hrs (%)±0.3±0.5Refractoriness Under Load @0.2M (oC)≥1,410≥1,350 Chemical Composition (%)Al2O3≥60≥36Fe2O3≤2.0≤2.5Q1: What is the main advantage of sillimanite-andalusite brick compared to high alumina brick?A1: It offers better thermal shock resistance, higher refractoriness under load, and stronger slag resistance, making it ideal for steel ladle and tundish linings.Q2: What is the typical working temperature of your product?A2: The bricks can continuously work at 1650-1700°C depending on the furnace type and working environment.Q3: Can you produce customized shapes or sizes?A3: Yes, we can produce customized blocks, skew bricks, arches, and special shapes based on your drawings or CAD design.Q4: How do you ensure quality consistency?A4: Each batch is tested for composition, porosity, density, and strength before shipment.We follow ISO9001 quality control standards for raw materials and production.Q5: Which industries commonly use this brick?A5: Mainly used in steel making (ladles/tundish), cement kilns, glass furnaces, and non-ferrous metal smelting.
