These containers serve to carry this fine material through the slag and
provide a means for quickly disseminating it through the metal, when it
is not convenient or possible to hold the steel longer than three or
four minutes in the ladle. This method of adding Ferro Carbon-Titanium
has proved of especial value in the treatment of Converter Steel. The
value of Titanium Treatment of Steel is now so well recognized and the
use of Ferro Carbon-Titanium so general that it is unnecessary to refer
to the properties of Titanium, which are well known to all metallurgists
and practical steel men. Titanium alone of all the deoxidizers leaves
practically no product of its oxidation in the finished steel. In rail
steel, for instance, which has been treated with Titanium the total
Titanium in the finished steel has never been found to exceed .03 and
any such amount as this is very unusual. This minute quantity is always
evenly distributed throughout the ingot and has never been found in
streaks or segregated areas as are Alumina, Manganese Sulphide, or Iron
Silicates. When Manganese or Silicon is added to a ladle of steel in the
form of Ferro Alloys from 65 to 8 j of the total Manganese or Silicon
will be found in the final product. These metals do not remain in the
steel uncom- The Titanium Alloy Manufacturing bined. They occur as
Manganese Carbide, Oxide or Sulphide, Iron Silicates, etc., and all of
these impurities, except the Carbide, are known to form streaks or
agglomerations which cause weak spots to develop in the metal...
