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。

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.
