摘要
中间包长水口吹氩缺乏监控钢水面以下气泡羽流的手段,这成为利用长水口吹氩去除钢水中夹杂物的障碍.提出了一种神经网络模型的新型算法,由钢水水面的波动形态推断钢水内部气泡羽流的形态,由数学模型构建数据集,经2000个数据集学习后,推断精度达到0.998.建立了水模型验证该算法,并利用该算法将水模型和数学模型相结合,优化了长水口吹氩工艺,使夹杂物去除率提高同时防止了卷渣现象的发生.
Abstract
Tundish long nozzle blowing argon lacks the means to monitor the bubble plume below the molten steel sur-face,which becomes an obstacle to the use of long spout blowing argon to remove inclusions in the molten steel.A new algorithm of neural network model was proposed to infer the morphology of bubble plume inside molten steel from the fluctuation pattern of the molten steel surface,and the dataset was constructed by the mathematical model.The results indicate that inference accuracy reaches 0.998 after learning from 2000 datasets.A water model was established to verify the algorithm,and the water model and mathematical model were combined to optimize the argon blowing process at the long spout,improving the removal rate of inclusions and prevent the occurrence of slag rolling.
