Abstract :
Piercer is an important equipment in seamless steel tubes production. The guide disc model is proposed by the analysis to hydraulic system which drives guide disc which is important for its control. Load-torque which is the important parameter in model is predicted by soft measure method. A PCA-ELM soft sensor model is proposed to estimate the guide disc speed in rolling piercing process successfully. The accuracy system is proved by simulation.
