The Effect of Andalusite on the Properties of Bauxite-Based Low-Creep High-Alumina Bricks

To achieve low-carbon, energy-efficient, and high-performance operation—characterized by elevated blast temperatures, extended service life, and large-scale capacity—in blast furnace hot blast stoves, increasingly stringent requirements have been imposed on the refractory materials utilized therein. Bauxite-based homogenized materials, produced through a process of homogenization and sintering, exhibit a uniform microstructure distribution as well as stable chemical … Read more

What are the Benefits of Impregnating High-Alumina Bricks with Phosphate?

Phosphorus impregnation of high-alumina bricks refers to placing fired high-alumina bricks in a container and impregnating them with phosphoric acid for more than two hours. After low-temperature treatment, their physical properties are significantly improved, making them suitable for use in harsh industrial furnace linings. Indicators of High-Alumina Bricks After Phosphating According to actual tests, after … Read more
