日本钢包炉的使用寿命约为 140炉次。使用过程中 ,风口砖、渣线砖以及包底熔池部均需要 2次修补炉。为提高钢包的使用寿命 ,降低耐材成本 ,日本对钢包渣线砖、风口砖和钢包壁耐材的材质以及包衬结构进行了改进。重点介绍了上述钢包各部耐材与包衬结构的改进和实用结果。指出 , The life of a ladle furnace in Japan is about 140 cycles. During use, the tuyere brick, slag brick and the bottom of the weld pool are required 2 times repair furnace. In order to improve the service life of the ladle and reduce the cost of the refractory, Japan has improved the material of the ladle slag brick, the tuyere brick and the ladle wall refractory material and the lining structure. The improvement and practical results of the refractory and lining structure of the ladle are introduced emphatically. Pointed out
