Best Quality in China Magnesia Calcium Bricks
Before the delivery of high alumina bricks, we will use professional testing equipment for testing, at least twice, and will deliver after the testing is completed. The testing equipment used by our company mainly includes:
1. High temperature RUL tester
2. Bulk density tester
3. Stress tester
4. Refractoriness tester

| 1. High Alumina Brick Description |
High alumina bricks are mainly made of clinker of bauxite and other materials, mixed at high temperature, formed, dried, and sintered. The Al2O3 content of high alumina bricks varies according to different ratios. The general content is stable at 48%-80%, the maximum alumina content can reach 90%, and the refractory temperature can reach 1770℃.
