摘要
用国产元件组成了钢水定氧同时预报铝镇静钢中酸溶铝([Al]_5)的快速预报系统。实测得出了鞍钢转炉条件下α[o],T和[Al]_5 间的统计预报关系。在满足技术要求条件下,测成率>90％,预报精度可靠。
A quick prediction system was set up with domestic elements/components used to determine oxygen content in molten steel and simultaneouly to predict the concentration of acid-soluble aluminium in Al-killed steel or [Al]5. A statistical-predictive relationship was thus measured among the activity of oxygen in molten steel a[o],temprature T and [Al],.as the measurements was taken from the converters in Anshan Iron and Steel Complex. It was indicated that the reliability is greater than 90% with high accuracy in predictive measurement if meeting the technical requirememts.
