The results indicate that, in either single or double blowing, larger erosion rate is mainly found in the slag line and near purging plug area of ladle lining; erosion is accelerated when gas flow rate increases; the erosion rate of ladle lining with double blowing is larger than that of single blowing; erosion rate distribution is obviously different as gas flow rate increases; in heavy blowing, serious erosion centers around slag line area and expands gradually outwards; as purging plug gets close to lining wall, malconformation of erosion rate in ladle lining becomes more prominent and the erosion rate of lining near purging plug increases.

结果表明，无论单吹还是复吹，较大的蚀损速率主要分布在钢包渣线及近透气砖区域，吹气量的增大会加速钢包内衬的蚀损。采用复吹时，钢包内衬的蚀损较单吹时更快。随着吹气参数的改变，钢包内衬蚀损速率的分布状况差异明显。大吹气量下，较大的蚀损集中在渣线区域且呈环向扩展；透气砖安装距包壁越近，钢包内衬蚀损不均衡性也越突出，近透气砖内衬蚀损加重。
