摘要
基于声学原理所研制的转炉造渣监控系统为转炉冶炼提供了有效手段，在实际应用中取得了良好的冶金效果。通过采集炉内音强信息，该系统能自动设置炉渣喷溅和返干预警线及最佳化渣区域，并显示枪位和副原料加入情况等，以指导工人操作，该系统能提前５～１０ｓ预报喷溅和返干，其预报命中率分别为８６．７％和９４．６％。另外，该系统还有预报熔池含磷量的功能。
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.
