Corundum Series
Special Corundum-Mullite Composite Brick
A corundum-mullite brick (Al₂O₃ ≥ 80 %) with RUL ≥ 1700 ℃ for high-temperature and transition zones of lime, magnesium-metal and bauxite rotary kilns; an insulating triple-layer version is offered on request.
Overview
Corundum-mullite composite brick with Al₂O₃ ≥ 80 % and Fe₂O₃ ≤ 1.0 %, RUL ≥ 1700 ℃ (0.2 MPa, 0.6 % deformation). A triple-layer insulating version is available on request.
Applications

FAQ
Why do RUL values appear as T0.5 or T0.6?
They come from different methods: YB/T 370 (non-differential) reports T0.6, GB/T 5989 / ISO 1893 (differential) reports T0.5, and the two cannot be converted. Jinxing's current data are reported at 0.2 MPa / 0.6 % deformation (T0.6).
Are the data-sheet values guaranteed?
Unless marked "Spec", values are typical and for reference only; each shipment is supplied with its own inspection report.
How do I choose between silica-mullite, phosphate-bonded and corundum composite bricks?
It depends on the dominant wear mechanism in each zone (temperature, chemical attack, abrasion). Silica-mullite and phosphate-bonded wear-resistant bricks are typically used in transition, cooling and medium-temperature wear zones; corundum-based products are used where temperature and slag attack are severe. Send us your kiln data and our engineers will propose a zone-by-zone design.
