日本神户钢铁公司加古川炼铁厂用铁水罐车进行铁水预处理(鱼雷车氧化工艺),现在铁水预处理比率约为25％。按运铁水量汁,铁水罐车的寿命约30万吨。该铁水罐车在顶部采用烧成高氧化铝质砖,渣线以下部位使用Al_2O_3—SiC—C质砖。内衬砖的损伤在渣线部位最严重,为了延长内衬寿命,需要提高该部位耐材的耐蚀性。为此,开发了向Al_3O_3—SiC—C质砖中添加β—氧化铝 Kakogawa Iron Works, Japan’s Kakogawa Ironworks, uses a hot metal ladle car for hot metal pretreatment (torpedo car oxidation), and now has a hot metal pretreatment ratio of about 25%. According to the iron volume of water transport, the life of the metal tanker about 300,000 tons. The hot metal tank car fired at the top with high alumina brick, the following parts of the slag line using Al_2O_3-SiC-C brick. Lining brick damage in the slag line parts of the most serious, in order to extend the life of the lining, the need to improve the corrosion resistance of refractory parts. For this reason, it has been developed to add β-alumina to Al 3 O 3-SiC-C brick
