RH炉浸渍管外衬刚玉-尖晶石浇注料的研制

Development of corundum-spinel castable for outer lining of RH snorkel

通过选择合适的超细粉加入量、镁砂粒度组成及加入量 ,优化基质的组成 ,利用Al2 O3与MgO在使用过程中直接生成尖晶石 ,研制的刚玉-尖晶石浇注料具有优良的抗渣性、耐剥落性以及适度的微膨胀。

The castable was developed by choosing suitable ultrafine powder addition, magnesite particle size composition and addition and optimizing matrix composition. The castable is characterized by superior slag resistance, spall resistance and proper little expansion.
