Electrofused refractory

Japanese: 電鋳耐火物 - でんちゅうたいかぶつ(英語表記)electrofused refractory
Electrofused refractory
Refractories are made by melting refractory raw materials in an electric furnace and pouring them into a mold in the same way as metals. Electrocast refractories were developed in the United States in 1926 and were used in glass kilns as alumina-silica refractories, which gave them revolutionary durability. While ordinary refractories are particle-bonded and have many pores, electrocast refractories have a monolithic structure with almost no pores, which significantly reduces contact reactions with the molten material and greatly extends their durability. Another feature is that new synthetic minerals can be obtained by electric melting, such as the alumina-silica synthetic mullite 3Al 2 O 3 ・2SiO 2 .

電気炉で耐火物原料を溶融し,これを金属と同じように鋳型に注入して鋳込んだ耐火物。電鋳耐火物は1926年アメリカで開発され,アルミナ・シリカ質耐火物としてガラス窯に用いられて,革命的な耐用性を得たことに始まる。一般の耐火物が粒子結合して気孔が多いのに対して,電鋳耐火物は気孔のほとんどない一体組織をしているために,溶融物との接触反応が著しく少なくなり,耐用性が大幅に延長する特徴をもっている。また電気溶融により新しい合成鉱物が得られることも特徴であり,アルミナ・シリカ質の合成ムライト3Al2O3・2SiO2などがその例である。
