Introduction to High Alumina Wedge Bricks
High alumina wedge bricks are specialized tapered refractory bricks designed for curved, arched and circular furnace linings. Unlike ordinary straight refractory bricks that cause gaps and loose lining on arc surfaces, high alumina wedge bricks enable tight, seamless and stable installation. Produced from high-purity bauxite raw materials, these shaped refractory bricks deliver superior high-temperature resistance, excellent thermal shock stability and reliable anti-slag performance, widely applied in cement rotary kilns, metallurgical furnaces, power boilers and industrial high-temperature equipment.
Standard T-Series High Alumina Wedge Brick Types
Our complete T-series wedge bricks cover three core specifications for different lining scenarios. Vertical thick wedge bricks, known as axe-type bricks (T19, T20, T41), taper in thickness, perfectly suited for furnace arch tops and large curved furnace walls with stable load-bearing capacity. Side thick wedge bricks, or knife-type bricks (T38, T39), feature narrowed side width, ideal for rotary kiln and cylindrical furnace inner linings to improve overall compactness. Vertical thin wedge bricks (T43, T44, T45) adopt a small taper design, catering to small-diameter flues and miniature cylinder transition sections requiring precise fitting.
Core Performance Benefits
Standard T-series wedge bricks eliminate on-site brick cutting, greatly saving construction time and reducing project costs. These high alumina wedge bricks sustain long-term working temperatures up to 1770°C, featuring low high-temperature creep, stable mechanical strength and strong abrasion resistance. They resist frequent heating and cooling cycles, effectively preventing lining cracking and peeling, and significantly extending the overall service life of industrial kiln linings.
Strict Quality and Custom Service
All our T-series wedge bricks undergo strict quality inspection with accurate dimensional tolerance and stable physical and chemical indexes. In addition to standard sizes, we provide customized non-standard high alumina wedge bricks to fit special furnace radii and unique structural designs, meeting diverse industrial refractory lining requirements.
