| 摘 要： | 攀钢大高炉冶炼中发现含氧化钛高于25%的渣,出现泡沫渣现象,并溢出渣罐妨碍生产。生成泡沫渣有两个条件:一是在熔渣内部有足够大量而分散的气体源;二是熔渣表面张力低、表观粘度高,使气泡稳定且有足够的机械强度、不易破坏或合并。已证实在含氧化钛高炉渣中悬浮着碳化钛、氮化钛及碳氮化钛微粒,这些微粒提高了熔渣的表观粘度,是使气泡稳定的重要因素之一。有人用气泡最大压力法,测定含氧化钛高炉型渣的表面张力,指出氧化钛是表面活性物质。但

| Abstract: | The surface tension of quinary blast furnace type synthetic slags containg titanium
oxides has been measured by means of sessile drop method. The influences of TiO_2, MgO and
basicity on the surface tension of the slag has also been studied. It was found that TiO_2 is a
surface active component. The surface tension of quinary slag may increase as TiO_2 was substi-
tuted by the same quantity of lower-valent titanium oxides. |
