Abstract
The method for the complete isolation of the oxide inclusions from rimmed steel was studied. The results obtained are as follows.
(1) In the case of using the generally applied alcoholic-iodine method, only a part of the oxide inclusions can bc isolated from rimmed steel.
(2) In the case of using the newly developed method using iodine-methanol solution containing a small amounts of Na- alcoholate, the oxide inclusions can be almost isolated from rimmed steel.
(3) The oxide inclusions present in rimmed steel consist mainly of (Mn, Fe) O, which is enriched with manvanese.
