Based on the practical effect, the corrosion resistant method using double layer graphite lining and natural hard rubber layer in between steel shell and graphite plate is a successful method.

This system realizes data acquisition and processing of linear CCD based on DSP, and achieves the goal of hot rolling steel plate size real-time measurement in high speed.

In allusion to automation of the art of steel plate bending by line cooling and heating, a special industrial robot based on SERCOS is introduced in this paper.
