Product Description
Firecrete Super is a high-grade, 70% alumina conventional dense refractory castable designed for applications requiring high thermal stability and mechanical strength. It is a hydraulic-setting "monolithic" refractory, meaning it is supplied as a dry powder that, when mixed with water, forms a heat-resistant concrete.
Description and Key Properties
Firecrete Super is primarily used in less critical zones of industrial equipment to provide a cost-effective, durable lining.
-
Maximum Service Temperature: Up to 1450C.
-
Chemical Composition: Contains approximately 70% Alumina ($Al_{2}O_{3}$) and a maximum of 5.5% Iron Oxide ($Fe_{2}O_{3}$).
-
Nature of Bond: Hydraulic, allowing it to set like standard cement after the addition of water.
-
Physical State: Supplied as a greyish-white dry powder, typically in 25kg or 50kg bags.
-
Performance: It offers excellent mechanical strength and resistance to thermal shocks, maintaining its structural integrity under intense heat.
-
Common Uses: Ideal for boiler linings (especially in the sugar industry), ovens, baking furnaces, and flue gas or hot air ducts.
Directions for Use
Proper installation is critical to ensure the longevity of the refractory lining and prevent issues like cracking or "spalling" (explosive steam release).
1. Preparation
-
Surface Cleaning: The application area must be free of dust, oil, and grease.
-
Formwork: Use watertight and rigid forms (usually mild steel or plywood). Coat them with a release agent like mold oil to ensure easy removal after setting.
-
Anchors: If using steel anchors, coat them with a thin layer of bitumen or plastic to allow for metal expansion during heating.
2. Mixing
-
Water Quality: Use only clean, potable (tap) water.
-
Water Ratio: Add 10% to 11% water by weight (approximately 2.52.75 liters per 25kg bag).
-
Process: * Dry mix the powder for about 1 minute.
-
Add water incrementally and mix for 35 minutes until uniform.
-
-
Consistency Test: Perform a "ball-in-hand" test. Toss a ball of the mix 1530 cm into the air; it should adapt to the shape of your hand when caught without crumbling (too dry) or flowing through your fingers (too wet).
3. Installation (Casting)
-
Timing: The mixture must be placed within 20 to 30 minutes of adding water.
-
Compaction: Use a high-frequency mechanical vibrator to ensure high density and remove air pockets.
-
Surface Finish: Trowel only enough to level the surface. Do not create a slick, polished finish, as this can trap moisture.
4. Curing and Drying
-
Curing: Keep the castable covered with wet gunny bags or plastic sheets for at least 24 hours after the initial set to maintain moisture for proper bonding.
-
Air Drying: Allow the material to air dry for an additional 24 hours after removing the forms.
-
Initial Heat-up: Follow a controlled heating schedule. Raise the temperature slowly (e.g., 25C per hour) to 110C and hold until all steaming ceases before proceeding to higher temperatures.
Reliable Performance in High-Temperature Environments
Designed for robust performance, Medium Purity Dense Castable stands up to demanding conditions in industrial furnaces and thermal processing units. The material's high compressive strength and dense finish make it an ideal choice for applications where durability and longevity are essential. This castable ensures structural integrity and optimal thermal efficiency, supporting operations in a wide temperature range.
Versatile Application and Customization
This dense castable is versatile in its application, suitable for furnace linings and other high-temp installations. Available in powder form and 25 kg packaging, it can be tailored to fit specific size requirements, providing flexibility to contractors, fabricators, and service providers. Its easy mixing properties with recommended water addition make it user-friendly on various sites.
FAQ's of Medium Purity Dense Castable:
Q: How is Medium Purity Dense Castable prepared and applied for furnace lining?
A: Mix the castable powder with 7% to 10% water by weight to achieve a homogeneous consistency. The mixture should be poured or cast into the desired mold or area, then allowed to set, completing its final set within a maximum of 8 hours. Proper curing enhances its compressive strength and longevity.Q: What benefits does using this dense castable provide in industrial settings?
A: This product offers excellent mechanical strength (40-50 MPa after 24-hour air dry), superior thermal resistance (up to 1600C), and low thermal conductivity, which collectively enhance furnace performance and service life. Its density ensures a durable lining, minimizing maintenance and maximizing efficiency.Q: When should this castable be used over other refractory options?
A: Medium Purity Dense Castable is optimal for use in processes requiring both high strength and resistance to high temperatures, such as in furnace linings or industrial kilns. It is particularly suitable where a denser, more robust lining is needed, and when custom sizing is necessary.Q: Where can this product be sourced in India, and who are the main suppliers?
A: The dense castable is available through leading dealers, distributors, manufacturers, exporters, suppliers, and wholesalers across India. Reputable retailers and service providers also stock this product, making it widely accessible to various industries.Q: What is the recommended storage process for maintaining shelf life?
A: To ensure the product retains its properties for up to 12 months, store it in a dry, cool area away from moisture. Keep the packaging sealed until use, and avoid exposure to direct sunlight or humidity.Q: Can the size and quantity of this castable be customized for specific projects?
A: Yes, the product offers size customization options to suit project-specific requirements. It is packaged in 25 kg bags, but bulk quantities and tailored dimensions can be arranged through suppliers or directly with manufacturers.Tell us about your requirement
