中空粒子としてシリカ-アルミナ系中空粒子を40重量%、母材としてシリカ-アルミナ系粉末を60重量%、これらを混合して強度確保用焼失材を含有しない比較例2を作製した。この実施例の耐火物用断熱材に液状バインダーを添加して吹付断熱材を作製し、耐火物(連続鋳造用ノズル)20の表面に吹き付けて乾燥させ断熱層を形成した。
比較例1、比較例2および実施例の耐火物用断熱材にて形成された断熱層の構造強度を測定したところ、図2の表の上段に示すように、比較例1による断熱層の構造強度は2.48N/mm2、比較例2による断熱層の構造強度は0.67N/mm2、実施例による断熱層の構造強度は2.39N/mm2であった。これにより、比較例2の中空粒子40重量%のうち、20重量%を強度確保用焼失材に代替させた実施例では、断熱層の構造強度が高まることが確認された。
