摘　　要：针对中小转炉不宜增设副枪检测、无法进行动态控制的实际状况，提出了自适应静态模型动态化控制的思想：首先建立自适应终点静态控制模型；然后根据枪位－加料模型进行吹炼并启动动态化控制知识库，修正枪位－加料模型及控制量，最后启动预报模型进行终点预报指导出钢，根据实际吹炼数据验证，终点控制模型具有良好的跟踪性，终点预报模型的终点Ｃ，Ｔ命中率分别达到６８％和６３％。Because of their operational condition, it is difficulty to use sublances to mesure and to conduct dynamic control in the small and medium sized converters. The method of dynamic control over the adaptive static model was presented. Based on the adaptive static final-point control model and the oxygenlance position-charging model, adjust the lance position and other control variables. And then a predication model is started to predict the operational targets and the time for tapping. The results of prac-tical testing have shown that the final-point control model hus good ability to adapt, and accu- racy of the predicted targeting carbon content and temperature by the prediction model reaches 68% and 63% respectively.
