<p>PURPOSE:To efficiently denitrify molten steel independently of the compsn. with a small amt. of a flux while nearly preventing the drop of the temp. by impressing DC voltage so that the molten steel is made negative and slag positive and electrolytically refining the molten steel. CONSTITUTION:Molten steel 1 is charged into a ladle 7 fitted with the cathode 4 at the bottom, slag 2 is added to the molten steel 1, a hood 8 is set on the ladle 7 and the anode 3 of graphite, etc., is immersed in the slag 2. Voltage is impressed between the molten steel 1 and the anode 3 from a DC power source 5 through a cable 6 so that the molten steel 1 is made negative and the slag 2 positive and the molten steel 1 is electrolytically refined. Efficient denitrification can be carried out with a small amt. of a flux.</p> |
