选用Ｔｉ脱氧钢研究了钢中氧含量对氧化物尺寸的影响，观察了连铸钢板中氧化物尺寸与数据，测量了细微氧化物的体积分数和钢水冷却凝固过程中以氧化物形式沉积的氧含量，得出如下结论：主要由Ｔｉ２Ｏ３，Ａｌ２Ｏ３，ＭｎＯ组成的细微复杂氧化物的数量和直径随钢中氧含量的增加而增大，钢中的氧几乎全以氧化物形成存在，即钢中氧含量几乎等于氧化物含量。钢冷却凝固过程中沉积的氧化物相当于钢中氧化物总量的７０％，并且尺寸大多小于１０μｍ。轧制前钢水中存在的大多数氧化物也是细微的，原因是这些细微氧化物不能浮起而从钢水中分离，结果是悬浮在钢水中，尺寸小于１０μｍ的氧化物为钢中总氧化物的大部分，并决定着钢中的氧含量
The effect of oxygen content in steel on oxide size was investigated by using Ti deoxidized steel. The size and data of oxide in continuous casting steel were observed. The volume fraction of fine oxide and the oxygen in the form of oxide during the solidification of molten steel Content, come to the following conclusion: The number and diameter of the fine and complex oxides mainly composed of Ti2O3, Al2O3 and MnO increase with the increase of the oxygen content in the steel, and the oxygen in the steel almost completely exists in the form of oxides, that is, The oxygen content is almost equal to the oxide content. The amount of oxide deposited during the cooling and solidification of steel is equivalent to 70% of the total amount of oxides in the steel and the size is mostly less than 10 μm. Most of the oxides present in the molten steel prior to rolling are also subtle because these fine oxides can not be separated from the molten steel and as a result, are suspended in the molten steel. Oxides less than 10 μm in size are the total oxides of steel Mostly, and determines the oxygen content in the steel
