Sonar Monitored Control Method for Slag-making in Converter
-
摘要: 基于聲學原理所研制的轉爐造渣監控系統為轉爐冶煉提供了有效手段,在實際應用中取得了良好的冶金效果。通過采集爐內音強信息,該系統能自動設置爐渣噴濺和返干預警線及最佳化渣區域,并顯示槍位和副原料加入情況等,以指導工人操作,該系統能提前5~10s預報噴濺和返干,其預報命中率分別為86.7%和94.6%。另外,該系統還有預報熔池含磷量的功能。Abstract: Slag-making monitored control system which based on sonic level provided a useful method for steelmaking in converter. According to the sonic level in converter, the system can decide the optimum slag-making region autornatically, and show the lance hight and the information of fluxes charging in ordor to guide steelmaking operation. 5 to 10 seconds before slag overflow or slag over-viscous, the system can give an advance warning with the hitting ratio of 86.7% for slag overflow and 94.6% for slag over-viscous. In addition, the system has the function of predicting the content of. phosphorus in bath.
