| Abstract: | The electric gap of a rolling mill can be measured directly by using DGMI linear position transducer of screw,which provides a basis for high-accuracy electric gap control(EGC).Methods for adjusting the parameters to improve the positioning accuracy and speed have been proposed by investigating the position control characteristic curve of EGC.Good results obtained in the plate mill of Hebei Jingye Group reveal the effectiveness of the technology. |
