| 摘 要： | 莱钢特钢厂90t转炉喷溅的主要原因是突发性碳氧反应、熔池温度骤降和FeO过多积累、高硅高磷铁水和留渣操作等。通过优化枪位控制、加料时机控制、熔池温度控制、留渣操作控制等,使钢铁料消耗降低了5.5kg/t、喷溅渣降低了8.1kg/t,使耐材消耗、氧气消耗、石灰消耗分别降低了0.22kg/t、1.2m3/t、1.8kg/t。

| Abstract: | The main slopping reasons of the 90 t converter in Laiwu Steel Special Steel Plant were paroxysmal carbon-oxygen reaction,excessive FeO accumulation,hot metal with high-silicon and high phosphorus,remaining slag operation and so on.Through optimizing lance control,feeding time control,molten pool temperature control,remaining slag operational control and other measures,the steel material consumption was reduced by 5.5 kg/t and splashing slag reduced by 8.1 kg/t.It made the consumption of the refractory,oxyg... |
