MOLTEN IRON TRANSPORT CONTAINER FOR MAKING IRON
PROBLEM TO BE SOLVED: To provide a molten iron transport container for making iron with a carbon-containing brick refractory processed, having enhanced spalling resistance without losing fibrous materials even during transporting molten iron.SOLUTION: There is provided a molten iron transport container for making iron that is for transporting molten iron or applying a preliminary treatment on the molten iron during transporting the molten iron, which is constituted by a work refractory, a perpetual refractory and iron coating in this order from an inner side, wherein a carbon-containing brick refractory formed by curing a mixture raw material containing following (1), (2) and (3) is used for the work refractory. (1) at least one compound of AlOand MgO having particle size range of particle diameter of 3 mm or more of 5 to 40 mass%, 1 mm or more and less than 3 mm of 10 to 45 mass%, 0.15 mm or more and less than 1 mm of 15 to 30 mass% and less than 0.15 mm of 5 to 45 mass%. (2) a graphite raw material. (3) at least two powders of MgO, AlOand SiOhaving an average particle diameter of 1 μm or less.SELECTED DRAWING: Figure 6
【課題】溶銑を輸送しても繊維状物質が消失しない耐スポーリング性を向上させたカーボン含有れんが耐火物を施工した製鉄用溶銑輸送容器を提供する。【解決手段】溶銑を輸送する、または前記溶銑を輸送する途中で前記溶銑に予備処理を実施するための製鉄用溶銑輸送容器であって、前記製鉄用溶銑輸送容器は、内側からワーク耐火物、永久耐火物、鉄皮の順に構成され、前記ワーク耐火物に、下記（１）、（２）および（３）を含む混合原料が硬化されたカーボン含有れんが耐火物を用いることを特徴とする製鉄用溶銑輸送容器。（１）粒径で３ｍｍ以上が５〜４０質量％、１ｍｍ以上３ｍｍ未満が１０〜４５質量％、０．１５ｍｍ以上１ｍｍ未満が１５〜３０質量％、０．１５ｍｍ未満が５〜４５質量％の粒度範囲からなるＡｌ２Ｏ３およびＭｇＯの少なくとも１種類の化合物。（２）黒鉛原料。（３）平均粒子径が１μｍ以下であるＭｇＯ、Ａｌ２Ｏ３、ＳｉＯ２のうち少なくとも２種類の粉体。【選択図】図６
