MOLTEN IRON PRETREATMENT CONTAINER
To provide a molten iron pretreatment container capable of improving the durability of a workpiece refractory therein and remarkably increasing the usage count thereof.SOLUTION: In a molten iron pretreatment container for holding or/refining a molten a workpiece refractory at least at a part of a region on a side upper than an iron bath part therein is composed of a magnesia-spinel brick, in which, in chemical components, the content of Al2O3 is 1 or more to 44 mass% or less, the content of MgO is 55 or more to 98 mass% or less, and the total content of the Al2O3 and the MgO is 80 or more to 99 mass% or less. The refractory lining structure of the molten iron pretreatment container has excellent erosion resistance and crack resistance so as to withstand the severe service conditions of molten iron pretreatment treatment to remarkably improve durability compared with the conventional refractory lining structure.SELECTED DRAWING: Figure 1
【課題】容器内のワーク耐火物の耐用性を向上させ、溶銑予備処理容器の使用回数を大幅に増大させることができる溶銑予備処理容器を提供する。【解決手段】溶銑を保持または／および精錬するための溶銑予備処理容器であって、溶銑予備処理容器内における銑浴部よりも上側の領域の少なくとも一部のワーク耐火物を、化学成分中のＡｌ２Ｏ３量が１質量％以上４４質量％以下、ＭｇＯ量が５５質量％以上９８質量％以下、Ａｌ２Ｏ３とＭｇＯの合計量が８０質量％以上９９質量％以下であるマグネシア・スピネル質れんがで構成する。この溶銑予備処理容器の耐火物ライニング構造は、溶銑予備処理の苛酷な使用条件に耐え得る優れた耐溶損性と耐割れ性を有し、従来の耐火物ライニング構造と比較して耐用性が顕著に向上する。【選択図】図１
