Abstract：The evolution of inclusions during ESR and the microstructure of 8Cr13MoV martensitic stainless steel as-cast ingot were studied under the conditions of different current intensity and cooling rate. The results showed that， after electroslag remelting， the main inclusions of 8Cr13MoV steel were MnS， TiN， Al2O3 and complex inclusions（Al2O3 core surrounded by （Ti， V）N layer）. The change of current intensity and cooling rate of the ESR process had no effect on the types of inclusions. With the increase of the current intensity during ESR process， the number and the area ratio of inclusions in ESR ingot decreased， and the number of inclusions with small size increased. With the increase of the cooling rate during ESR process， the number of inclusions was almost constant， the area ratio of inclusions decreased， while the number of inclusions with small size increased， resulting in a refining distribution of inclusions.
