用座滴法测定了元素周期表第6族b '柱元素（O、S、Se和Te）对铁水表面张力和铁水与固体氧化物接触角的影响，研究了碲对铁水中氧化物夹杂（氧化铝、莫来石和氧化锆）的消除作用。结果发现，所有这些元素作为表面活性剂，并在铁水中的表面活性增加的顺序为氧，硫，硒，碲。铁液与氧化铝之间的接触角随氧的加入而减小，随硒和碲的加入而增大，而硫几乎没有影响。此外，随着铁液中碲含量的增加，铁液与氧化镁、莫来石、氧化锆等氧化物的接触角也随之增大，铁液中的夹杂物数量随着碲含量的增加而明显减少。
AbstractThe effects of the elements of the b'column of the 6th group of the Periodic Table (O, S, Se and Te) on the surface tension of molten iron and the contact angle between molten iron and solid oxides have been measured with the sessile drop method.The effect of tellurium on the elimination of oxide inclusions (alumina, mullite and zirconia) from molten iron has been investigated. It was found that all of these elements acted as surface-active agents and in molten iron the surface activity increased in the order oxygen, sulphur, selenium, and tellurium. The contact angle between molten iron and alumina decreased with the addition of oxygen and increased with that of selenium and tellurium while sulphur scarcely had any effect. Moreover the contact angles on other oxides such as magnesia, mullite, and zirconia also increased with increasing tellurium content in the molten iron.The amount of inclusions in the molten iron decreased considerably with the addition of tellurium during the deoxidation with ...
