The products smooth surface finish and excellent water absorption rates facilitate efficient installation and setting, with an initial set time of 35 hours and final set within 810 hours. Packaged in sturdy HDPE bags, the material remains clean, protected, and ready for immediate use on-site.

FAQs of High Alumina Castables And Mortar Powder:

Q: How should High Alumina Castables and Mortar Powder be used in industrial applications?

A: These castables and mortar powders are suitable for constructing and repairing linings in furnaces, kilns, boilers, and incinerators across steel, cement, and glass industries. They can be applied by casting or trowelling according to the specific design and thickness requirements. Proper mixing with clean water and installation as per guidelines ensures optimal performance.

Q: What is the storage process for maintaining product shelf life?

A: To maximize the 12-month shelf life, store the material in its original HDPE bags, in a cool, dry place away from direct moisture. Avoid storing the product near open sources of water or in high-humidity areas to prevent premature setting or degradation of quality.

Q: When is it appropriate to apply the material after mixing?

A: Once mixed with water, the High Alumina Castables and Mortar Powder should be applied within the initial setting time frame of 35 hours, and installation should be completed before the final set (810 hours). Delays beyond this period may impact workability and performance.

Q: Where can these castables and mortar powders be used?

A: The product is ideal for use in high-temperature, chemically aggressive environments such as steelmaking furnaces, cement rotary kilns, boilers, incinerators, and glass production units. Its versatility also makes it suitable for repair work wherever strong resistance to heat and corrosive substances is required.

Q: What benefits does using this high alumina product provide over conventional materials?

A: High Alumina Castables and Mortar Powders offer superior cold crushing strength, high refractoriness, low residual expansion, and excellent resistance to slag and alkali attack. This results in longer service life, reduced maintenance, and improved energy efficiency for industrial furnaces and other high-temperature applications.

Q: How is the products resistance to contamination by slags and alkalies ensured?

A: The high alumina content (5090%) and carefully selected additives provide excellent chemical stability. This composition allows the refractories to resist penetration and corrosion by slags, alkalies, and other aggressive agents commonly encountered in metallurgical and kiln environments.
