VESSEL FOR IRON-MAKING AND OPERATION METHOD OF VESSEL FOR IRON-MAKING
To provide a vessel for iron-making capable of improving spalling resistance of a refractory by undergoing a pre-heat treatment of the vessel for iron-making after installation to the vessel for iron-making of a refractory and an operation method of the vessel for iron-making.SOLUTION: An iron-making vessel used for iron-making, which is composed of a work refractory, a permanent refractory, and an iron shell in this order from the inside, and at least a part of the work refractory uses a carbon-containing non-fired brick refractory that contains the following (1), (2), and (3). (1) Refractory raw material (2) Graphite raw material (3) A mixture obtained by mixing a transition metal having an average particle size of 1 μm or less or a transition metal compound containing a transition metal in a liquid binder made of an organic material.SELECTED DRAWING: Figure 8
【課題】耐火物の製鉄用容器への施工の後に当該製鉄用容器の予熱処理を経ることで、耐火物の耐熱スポーリング性を向上させることができる製鉄用容器および製鉄用容器の操業方法を提供する。【解決手段】製鉄に用いられる製鉄用容器であって、内側からワーク耐火物、永久耐火物、鉄皮の順に構成され、前記ワーク耐火物の少なくとも一部に、下記（１）、（２）、及び（３）を含む混合原料が含有されたカーボン含有不焼成れんが耐火物を用いる、製鉄用容器。（１）耐火物原料（２）黒鉛原料（３）平均粒子径が１μｍ以下である遷移金属又は遷移金属を含有する遷移金属化合物を有機系物質からなる液状のバインダーに混合した混合物【選択図】図８
