板状刚玉 3-5mm 粗粒骨料
板状刚玉3-5mm粗粒骨料，Al₂O₃≥99.2%，提升骨架强度，适用于钢包壁、电弧炉及玻璃炉蓄热室致密浇注料。
// 主要特性
- Coarse 3-5mm grains forming load-bearing skeleton in dense castable matrices
- Excellent thermal shock resistance due to uniform α-Al₂O₃ corundum microstructure
- Superior slag penetration resistance in steel ladle and EAF applications
- Low reversible thermal expansion reducing lining stress during thermal cycling
