| Abstract: | The 120t converter in Jigang adopts top-bottom blowing technology, and the bottom blowing system adopts LD-KGC weak stirring system feeding N_(2 )and O_(2 ) with manifold tuyere brick. Compared with general top-blown oxygen converter, the top-bottom converter has many characters such as bowing calmly, short smelting time, can producing ultra-low-carbon steel (0.01%~0.003%C) and low-phosphorus steel, the metal yield can be increased by 1% and the oxygen consumption can be reduced by 8%. |
