| Abstract: | The bottom blowing system of 80 t top-bottom blowing converter was reconstructed in 2008.The modified bottom blowing system is with simpler air supply structure and easy maintenance,which improve the mixing capability of furnace hearth,shorten time of oxygen supply during blowing,w(FeO) in final slag is lower,and the rate of dephosphorization is increased.Moreover,it is better to control composition and temperature of liquid steel precisely,and improve the quality of liquid steel. |
