... into a teeming ladle is too highly oxidized for immediate use because it contains about 0.04 to 0.1 wt% O. This level would cause blowholes in the steel if it were then solidified. Steel deoxidants such as aluminum, ferrosilicon, or carbon are therefore required to bring dissolved oxygen contents down...

... is important. Of critical importance is the way in which steel fills the mold. Two basic types of pouring methods have been used for transferring steel from the ladle to the ingot mold. They are top pouring and bottom pouring. Top Pouring Top pouring (or direct teeming) involves teeming from the ladle...

...) or in the ladle (VOD). The parameters that favor the choice of ladles as reaction vessels include the following: Tapping, treatment, and teeming are done in the same reaction vessel. Thus, there are no temperature losses due to any final transfer of the melt, and the high level of cleanliness achieved...
