Product Description
Important considerations
Trial batch The exact amount of water needed is determined by a trial batch to achieve the correct consistency where a formed ball should hold its shape when tossed up
Prefiring Specifications are often tested after prefiring to a specific temperature eg 110C110 raised to the composed with power cap C110 for 24 hours to remove initial water
Standards Test methods for properties like cold crushing strength and abrasion are often defined by national or international standards eg IS 1528
High-Performance Furnace Lining SolutionThis refractory castable is engineered for industrial settings requiring superior thermal stability and mechanical strength. Its high-alumina content and robust bonding enable reliable service in furnaces, boilers, and kilns that operate at extreme temperatures. The product's low porosity and fine particle distribution ensure excellent durability and heat resistance.
Versatile Application and Easy InstallationSuitable for casting, gunning, and vibrating applications, this castable adapts to various installation methods, allowing precise shaping and lining of complex furnace interiors. Customizable dimensions and a smooth finish make it ideal for both repairs and new installations in demanding industrial environments.
Quality, Packaging, and Storage GuidelinesEach batch is supplied in sealed 25kg or 50kg bags, securing a 12-month shelf life when stored in a dry, covered area. High compressive strength after firing enhances longevity, and the product retains low water absorption and optimal density for enduring operational efficiency.
FAQ's of Castable .:
Q: How should Refractory Castable 50 GMX be installed for best results?
A: For optimal performance, the castable can be applied by casting, gunning, or vibrating, depending on the specific furnace or kiln configuration. Mixing should use the recommended amount of water to ensure consistency. Proper site preparation and adherence to curing guidelines are essential for achieving maximum strength and heat resistance.
Q: What applications is this refractory castable suitable for?
A: This product is designed primarily for lining furnaces, boilers, and kiln repair in industrial settings. Its high compressive strength, resistance to temperatures up to 1600C, and low porosity make it ideal for any environment where durable thermal insulation is required.
Q: When does the castable reach its full strength?
A: The castable initially sets within 4 to 6 hours and develops its full compressive strength (over 70 MPa after firing) after the initial setting and subsequent controlled firing or exposure to operational temperatures in the furnace or kiln.
Q: Where should the castable be stored before use?
A: The castable should be kept in its original sealed packaging and stored in a dry, covered area away from moisture. Proper storage ensures a shelf life of up to 12 months, preventing premature setting or deterioration.
Q: What are the benefits of using this high alumina castable in industrial furnace linings?
A: The high alumina content offers excellent thermal stability, low water absorption, and resistance to both mechanical stress and chemical attack. These benefits result in extended service life, reduced maintenance, and efficient energy usage in high-temperature applications.
Q: How does the bonding agent in the castable work?
A: The hydraulic bonding agent reacts with water during mixing, ensuring quick setting times (4-6 hours) and generating initial strength needed for handling and installation. Once fired, it contributes to the castable's overall structural integrity.
Q: What is the typical appearance and texture of this castable?
A: The castable is supplied as a light grey or black, fine-textured powder or granular material. Once installed and fired, it maintains a smooth, dense surface finish, contributing to both its durability and heat resistance.
