| 摘 要： | 为了解铝和钛的氧化物在钢中的行为及其夹杂物的去除方法，采用静滴法在1873K及不同氧分压条件下，测定了纯铁、铝镇静钢和钛镇静钢在Al2O3和MgO垫片上的接触角，确认了液滴尺寸与接触角的关系及影响界面张力的因素，并提出了界面行为中线能量的重要性。

| Abstract: | In order to understand the behavior and removing method of Al_2O_3 and TiO_n in liquid steel, the investigation of interfacial properties is very important.The contact angles of pure Fe, Al-killed steel and Ti-killed steel in contact with Al_2O_3 and MgO substrates were measured by the sessile drop technique. The measurements were conducted at various oxygen potentials at 1 873 K.The studies were focused on other factors affecting interfacial properties. The result shows that the contact angle is a function of droplet size and the contact angles increase with increasing droplet size. In this area, the line energy which is an important factor was proposed for the first time. |
