Silicon Carbide Mullite Brick: Anti‑Spalling Composite Refractory for Rotary Kiln Linings

TY Refractory’s premium Silicon Carbide Mullite Brick is compound‑sintered from andalusite, brown corundum, high‑alumina clinker, silicon carbide and special binders. This composite refractory features high room‑temperature compressive strength, superior high‑temperature structural stability, outstanding thermal‑shock resistance, excellent wear‑proof and anti‑spalling performance for cyclic severe thermal and mechanical load inside rotary kilns.

This heavy‑duty brick delivers stable core technical parameters: Al₂O₃ 65‑75%, SiC 20‑30%, bulk density 2.6‑2.8 g/cm³, apparent porosity ≤14%, cold crushing strength ≥60 MPa and refractoriness ≥1790°C. Its dense matrix resists alkali‑sulfur erosion and mechanical scouring, forming a stable protective layer during long‑term kiln operation to slow lining degradation.

The versatile Silicon Carbide Mullite Brick is widely adopted for cement rotary kiln transition zone & kiln outlet, lime rotary kilns, nickel‑iron rotary kilns and other metallurgical thermal equipment. Custom‑shaped bricks can be strictly manufactured according to customer drawings for special kiln lining geometries.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Rigorous batch‑by‑batch in‑house inspection guarantees consistent quality. Global cement and metallurgical plants select our bricks to extend kiln campaign cycles and cut recurring maintenance costs.
