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.

Lime bearing agent for use in refining of ferrous melt

A method for preventing possible vapor explosion in the liquid comminuting process in metal refining comprising comparing pulse pressure generated in the course of liquid comminuting with a fixed reference pressure and adjusting the amount of molten metal thrown into water and the amount of water fed in accordance with the value of comparison.
