Copper Removal from Molten Steel by Gasification

Keywords： molten steel

A novel method is proposed to enhance the gasification and removal of copper from molten steel by adding ammonium salts or urea into molten steel under normal pressure. The decopperization experiments were conducted in a molybdenum-wire resistance furnace at 1 873 K. The copper content of about 400 g of a mild steel was reduced from 0.49 %(mass fraction, the same below) and 0.51 % to 0.31 % and 0.38 % using 0.7 g of NH4Cl and 0.5 g of (NH4)2C2O4 respectively, while the copper content of the molten steel was reduced from 0.61 % to 0.56 % using 2.00 g of NH2CONH2.
