粒径30〜500μmの粒子と粒径0.1〜30μmの粒子との割合が、50〜90重量%及び50〜10重量%であることを特徴とする断熱耐火物を提供するものである。
アルミナ粒子又はジルコニア粒子、水溶性高分子材料、多糖類、焼成によって消失可能な造孔粒子、及び液媒体を混練して得られた混練物を、該造孔粒子が破壊されない圧力でプレス成形して成形体を得、次いで
該造孔粒子が消失する条件下に該成形体を焼成する工程を有し、
アルミナ粒子又はジルコニア粒子として、粒径30〜500μmのものと、粒径0.1〜30μmのものとを用い、
粒径30〜500μmの粒子と粒径0.1〜30μmの粒子との割合を、50〜90重量%及び50〜10重量%とすることを特徴とする断熱耐火物の製造方法を提供するものである。
(1−嵩比重/見掛比重)×100の計算式から算出することができる。
(1)混練物の調製
骨材原料として平均粒径100μmの中実アルミナ粒子(純度99.7%)を70部用いた。また、ボンドとして平均粒径5μmの中実アルミナ粒子(純度99.8%)を30部用いた。水溶性高分子材料としてポリビニルアルコールを1部用いた。多糖類としてデンプンを2部用いた。造孔粒子として平均粒径3mmのスチレンビーズをアルミナ粒子100gに対して150cm3用いた。これらを10部の水と均一に混合して混練物を得た。
得られた混練物を金型内に充填し、100kg/cm2の圧力でプレス成形し、成形体を得た。この金型は図1に示す断熱耐火物に対応する形状を有していた。得られた成形体を100℃に加熱して水分含有率が0.5%以下になるまで乾燥を行った。成形体を観察したところ、造孔粒子の破壊は観察されなかった。
乾燥後の成形体を、空気中、1600℃で、5時間焼成し、図1に示す形状の耐火物を得た。この耐火物は、長さ230mm、幅115mm、厚さ65mmであった。
以下の表1に示す条件を用いて実施例1と同様にして、図1に示す形状の断熱耐火物を得た。
骨材原料として平均粒径150μmの中実のCaO安定化ジルコニア粒子(純度:ZrO295.6%、CaO3.7%)を60部、ボンドとして中実の平均粒径2μmのCaO安定化ジルコニア粒子(純度:ZrO295.6%、CaO3.7%)を40部、多糖類としてデンプンを2部、造孔粒子として平均粒径3mmのスチレンビーズ粒子をジルコニア粒子100gに対して100cm3用い、80kg/cm2の圧力でプレス成形した以外は実施例1と同様にして、図1に示す形状の断熱耐火物を得た。
以下の表1に示す条件を用いて実施例1と同様にして、図1に示す形状の断熱耐火物を得た。
イソライト工業株式会社製のアルミナ質耐火断熱レンガLBK−28(商品名)を比較例3とした。
実施例及び比較例の断熱耐火物について、上述の方法で気孔率を測定した。また、耐熱耐火物の化学分析を行った。これらに加えて断熱耐火物の圧縮強さ及び曲げ強さをJIS R2615及びJIS R2619に準じて測定した。更に耐アルカリ性を、下記の方法により評価した。その結果を以下の表2に示す。
坩堝に炭酸リチウム(Li2CO3)を入れ、実施例及び比較例で得られた断熱耐火物により蓋をした。坩堝を1000℃で10時間加熱した。その後、室温まで冷却し、断熱耐火物を坩堝から取り外した。取り外した断熱耐火物の炭酸リチウムと対向していた面の状態を観察し、該断熱耐火物の耐アルカリ性を評価した。評価基準は以下のとおりである。
○:断熱耐火物の表面の変化が観察されない
△:断熱耐火物の表面にボロツキは観察されないが、変色は観察される
×:断熱耐火物の表面にボロツキが観察される
