转炉炼钢氧枪枪位自动控制专家系统的实验室研究

在转炉造渣过程中，渣中FeO的含量直接影响到石灰的溶解速度、造渣途径和炉渣的喷溅、返干，在泡沫渣淹没吹炼状态下，调整氧枪枪位可有效地控制渣中FeO的含量。音平控渣系统，可以给出喷溅、返干的趋势，在此基础上，开发氧枪枪位自动控制专家系统，对喷溅、返干进行预测，采用自学习技术给出枪拉操作提示。此系统为氧枪自动控制奠定了基础。

LABORATORY STUDY ON AUTOMATIC CONTROLLING EXPERT SYSTEM OF LANCE HEIGHT IN BOF STEELMAKING

The amount of FeO in slag influences the lime dissolution,slag formation path and slag slopping and drying directly during slagging in BOF.In the immerge blowing state of foaming slag,the FeO content in slag could be controlled effectively by adjusting the oxygen lance height.The sonic detection system for controlling the slagging could show the tendency of slopping and drying,therefore,an expert system controlling lance height automatically was developed to do the prediction,and gives the information of the lance position by taking advantage of self learning technique,which laid a foundation to the lance automatic controlling.
