Highland Refractory can tailor dimensions, shape, and Al₂O₃ content according to your project specifications, providing technical guidance to ensure the right selection.
High alumina refractory bricks are essential in various industrial high-temperature zones:
Steel Blast Furnaces: Furnace walls, roofs, and working linings.
Cement Rotary Kilns: High-temperature sintering zones.
Glass Furnaces: Superstructure and critical high-temperature areas resistant to flux attack.
Non-Ferrous Metal Furnaces: Smelting and holding zones with high thermal loads.
Important Usage Note: High alumina bricks are ideal for stable high-temperature zones but are not recommended for areas with rapid thermal fluctuations, such as furnace doors or cooling sections.
Highland Refractory ensures the highest quality through strict control over raw materials and production processes:
Raw Material Selection: High-purity bauxite and selected clays.
Mixing: Precise ratios ensure consistent Al₂O₃ content.
Shaping: High-pressure extrusion or pressing for uniformity.
Drying: Controlled moisture removal prevents cracks.
High-Temperature Firing: Kiln firing at 1700–1800°C develops dense, strong bricks.
Quality Inspection: Every batch undergoes strict density, porosity, and refractoriness testing before export.
This process ensures Highland Refractory bricks meet both domestic and international standards, providing reliable and long-lasting performance.
