    Mar 10, 2014 · Phosphorus removal is carried out as early as possible in the heat. Hot heel practice is very beneficial in phosphorus removal because oxygen can be lanced into the bath while its temperature is quite low. Early in the heat, the slag contains high levels of FeO because it is carried over from the previous heat; this helps removal of phosphorus.
