本文从砖型结构、材质选择、制作、理化指标、使用效果以及损毁机理等方面较详细地进行了介绍和论证,说明以优质电熔镁砂、优质天然鳞片状石墨为主要原料,用φ500等静压机成型所制造出来的转炉复吹供气砖具有强度高、耐侵蚀性好、抗崩裂性强等优点。这种产品已在鞍钢180t转炉和济钢13t转炉上进行4个炉役的应用,普遍反映这种砖可在具有复吹条件下的5～180t转炉上推广使用。
In this paper, the brick structure, material selection, production, physical and chemical indicators, the use of results as well as the mechanism of damage and other aspects of a more detailed introduction and demonstration, that high-quality fused magnesia, high quality natural flaky graphite as the main raw material, with φ500 Static pressure molding machine manufactured by the converter blowing air brick with high strength, corrosion resistance, anti-cracking strong advantages. This product has been in the Ansteel 180t converter and 13t BOF Jinan Iron and Steel Company on the implementation of the four furnaces, a general reflection of this brick can have a complex blowing conditions 5 ~ 180t converter on the promotion and use.
