Description
140℃に加熱したフラタリー硅砂30kgをワールミキサーに入れ、これに表1に示す量で水溶性無機化合物を水450gに分散乃至溶解させた溶液を加え、約90秒間混練した。崩壊した後、滑剤としてステアリン酸カルシウム30gを添加して15秒間混練し、さらにエアーレーションを行なうことによって、粘結剤として水溶性無機化合物を含有するコーティング層で被覆した粘結剤コーテッド耐火物を得た。
140℃に加熱したフラタリー硅砂30kgをワールミキサーに入れ、これに表2に示す量のフェノール樹脂を加え、30秒間した後、さらに比較例1ではヘキサメチレンテトラミンを水450gに溶解したヘキサメチレンテトラミン水溶液を、また比較例2、3では水450を加え、混練した。崩壊した後、滑剤としてステアリン酸カルシウム30gを添加して30秒間混練し、さらにエアーレーションを行なうことによって、粘結剤としてフェノール樹脂を含有するコーティング層で被覆した粘結剤コーテッド耐火物を得た。この粘結剤コーテッド耐火物はさらさらとした粒状物であり、粘結剤コーテッド耐火物中のコーティング層の質量比率は2.0質量%であった。
崩壊率(%)=100−(加熱処理後の曲げ強さ/加熱処理前の曲げ強さ)×100
実施例3,12、参考例1,7、比較例1,2と同じ配合の粘結剤でコーティング層を被覆した粘結剤コーテッド耐火物を調製した。これらの粘結剤コーテッド耐火物を実施例17,19、参考例16,18、比較例4〜5とする。
