摘　　要：研究了镁对刀剪用钢中夹杂物的影响.试验结果表明:在中频炉出钢过程中加镁,可使钢中夹杂物由原来的以Al2O3和Al2O3-TiN为主,变为以镁铝尖晶石为主的夹杂物;加镁炉次铸坯洁净度为12.2个/mm2,不加镁铸坯为15.76个/mm2.The effects of magnesium on the inclusion in cutlery steel were investigated. It was shown that addition of mag- nesium into the steel in the tapping process of medium - frequency induction furnace resulted in a inclusion composed of MgO · Al2O3 spinel instead of Al2O3 and Al2O3 -TiN present in the untreated steel. The cleanliness of the billet was 12.2/ mm2 with magnesium deoxidation, compared to 15.76/mm2 without magnesium deoxidation.
