ABSTRACT:
A method of treating molten metals is disclosed which employs a solid sheathless flexible strand containing particles of the treating agent uniformly suspended in a binder matrix, the latter being consumable or vaporizable upon contact with molten metal. Positive and predetermined solution conditions of the treating agent are assured by regulating the molten metal flow velocity to be at or above a predetermined minimum and the strand injection rate to be within defined limits.
