ABSTRACT:
A slaking property of a lime bearing agent for use in the refining, particularly in the injection refining, of a ferrous melt is essentially eliminated by providing the agent with a special form, i.e. an uncrushed, granular form solidified from molten drops. Hydrogen pick up of the ferrous melt from the refining agent is avoided and an excellent refining effect of the ferrous melt is achieved by the refining agent of the present invention.
