Description

本発明は、高炉出銑樋用の内張り等に用いられる炭化珪素質流し込み材に関する。
高炉出銑樋は、高炉出銑口から排出される溶銑が通過する流路となるものであり、スラグ等による化学的浸食を受けやすいことから、耐食性に優れる炭化珪素質流し込み材を内張りすることが従来より行われている。
例えば、特許文献１には、耐火材料中に炭化珪素を５５〜９０質量％含む高炭化珪素含有不定形耐火物が開示されており、耐食性の向上が図られている。
特開２００２−２０１７７号公報
ところが、耐火物中に含まれる炭化珪素の割合が高くなると、流し込み材としての流動性が乏しくなる傾向があり、施工作業が困難になるという問題を有していた。
そこで、本発明は、耐食性及び施工性に優れる炭化珪素質流し込み材の提供を目的とする。
本発明の前記目的は、炭化珪素を６０〜９５重量％含み、微粉シリカを含まず、結合剤としてアルミナセメントを使用した耐火性粉体１００重量部に対し、カオリン系粘土０．１〜２．５重量部を外掛けで添加したことを特徴とする炭化珪素質流し込み材により達成される。
本発明によれば、耐食性及び施工性に優れる炭化珪素質流し込み材を提供することができる。
以下、本発明の実施の形態について説明する。本実施形態の炭化珪素質流し込み材は、高炉出銑樋用の内張り用として特に適したものである。
この炭化珪素質流し込み材は、耐火性粉体中に、炭化珪素を６０〜９５重量％含んでいる。良好な耐食性を得るためには、６０重量％以上の含有率が必要である一方、含有率が９５重量％より高くなると、流動性が低下すると共に、結合剤など他の添加剤の調整が困難になる。炭化珪素は、市販のものを使用可能であり、純度が９０％以上のものが好ましい。また、炭化珪素は、充填度を高めるために、超微粉から１２ｍｍ程度までの粒径分布を有することが好ましい。
耐火性粉体は、炭化珪素以外に、例えば、アルミナなどの耐火性原料、ピッチ、黒鉛粉末、カーボンブラックなどの炭素原料、アルミナセメントなどの結合剤、炭化硼素などの酸化防止剤、金属シリコン粉末などの焼結助剤を添加することができる。
本発明の炭化珪素質流し込み材は、カオリン系の粘土を、耐火性粉体１００重量部に対し、０．１〜２．５重量部を外掛けで添加したことを特徴としており、これによって、流動性及び耐酸化性を良好にしている。カオリン系粘土は、化学式Al2O3・2SiO2・2H2Oで表される粘土であり、カオリナイト、ディッカイト、ナクライト、ハロイサイトなどの鉱物を主体とするものを例示することができ、木節粘土、蛙目粘土なども使用可能である。
上記の炭化珪素質流し込み材は、施工時に水で混練し、型枠を用いて流し込み成形することにより、高炉出銑樋用の内張りを形成することができる。良好な分散効果を得るため、耐火性粉体に適宜分散剤を添加してもよい。
後述する実施例に示すように、カオリン系粘土の添加量は、加水混練物の流動性に大きな影響を与える。すなわち、耐火性粉体１００重量部に対して０．１重量部よりも少ないと、カオリン系粘土を添加した効果が十分得られず、必要な流動性を確保できない一方、２．５重量部よりも多い場合にも、粘性が高くなって流動性は低下する傾向にある。したがって、カオリン系粘土の添加量を上記数値範囲とすることで、加水量を必要最小限にしながら施工性を良好にすることができ、高炉出銑樋用に適した緻密な内張り層を形成することができる。カオリン系粘土の添加量は、耐火性粉体１００重量部に対して、外掛けで１．５重量部程度とすることが最も好ましい。
なお、本発明の炭化珪素質流し込み材は、カオリン系粘土の少量添加により流動性を確保できることから微粉シリカの添加は不要であり、この点からも耐食性の向上を図ることができる。
以下、実施例及び比較例に基づいて、本発明を更に詳細に説明する。但し、本発明は以下の実施例に限定されるものではない。
実施例１〜９及び比較例１〜６として、表1に示す割合の原料を混合し、表1記載の水量を加水混練した混練物を作成した。カオリン系粘土としては、木節粘土を使用した。
Figure 0005294624
表１において、耐火性粉体に占める炭化珪素の割合（重量％）は、６０、８０、９２．５の３種類とし、充填性が一定となるように、配合残部を占めるアルミナの粒径及び割合を調整した。この混練物の一部でフロー値を測定した結果を図１に示す。フロー値の測定は、JIS R 5201（セメントの物理試験方法）に準じて行った。
流し込み施工を良好に行うためのフロー値は、１２０以上が必要である。図１に示すように、カオリン系粘土の添加量（外掛け）が、耐火性粉体１００重量部に対し、０．１〜２．５重量部の範囲で良好な流動性を示す結果であり、約１．５重量部において流動性が特に良好であった。
本発明の実施例及び比較例について、流動性の測定結果を示すグラフである。
