| 摘 要： | 论述了超纯铁素体不锈钢夹杂物控制的热力学,着重于脱氧、TiN析出、尖晶石夹杂物形成及钙处理的热力学研究。介绍了VOD炉内夹杂物行为的数学模拟研究,分析了超纯铁素体不锈钢中夹杂物引起的产品缺陷、夹杂物形成规律及特征,指出TiN或Ti(CN)容易在MgO、Al2O3-MgO、Ti2O3基体上析出,形成包裹型复合夹杂物。最后提出了今后开展超纯铁素体不锈钢夹杂物研究的几点建议。

| Abstract: | This paper reviews the thermodynamics of inclusion control in the ultra clean ferritic stainless steel,focusing on deoxidation,TiN precipitation,formation of spinel inclusion and calcium treatment.The mathematical simulation of inclusion behavior in VOD is presented.The product defects caused by the inclusions and the formation rules and characteristics of inclusion are discussed.TiN or Ti(CN) is easy to precipitate on inclusions such as MgO,MgO-Al2O3 and Ti2O3,and the enwrapped complex inclusions are then ... |
