板状刚玉 1-3mm 中粒骨料
板状刚玉1-3mm中粒骨料，Al₂O₃≥99.2%，高堆积密度，适用于高炉铁沟、电弧炉及水泥窑高性能浇注料衬体。
// 主要特性
- Optimized 1-3mm gradation for intermediate matrix packing in multi-fraction castables
- Closed porosity structure delivering low wettability by molten slag and metal
- High hot modulus of rupture for impact-resistant blast furnace trough linings
- Consistent grain shape and hardness reducing segregation during castable mixing
