This study is made to suit the hot strip mill plant in A.R.E. the material in this text is arranged in such a way that several section in a chapter can be deleted without loss of continuity .
The first part explains the rolling technological processes , the method of local control, and its operations as temperature, control mill set up , mill pacing, and production logging.
The second part is devoted to the detailed , design gauge control, the causes of the gauge variations and the method of corrections being included here in.
The static characteristics are discussed in details as well as the dynamic ones, and the two methods of thickness control by an adjustable screw-down or by the tension are also discussed in details.
The automatic control systems for the six stands are composed using the two methods of thickness measurement. The control is made also by the two methods. Two new methods are used to correct the gauge variations.
A special part is devoted to the measuring systems used in hot strip mills, they are explained and specified definitely .
Some economical indices are discussed in chapter 4, and finally the precautions of the mill personnel are recommended in the last part , the calculations of protective screen against X-ray radiation is made.
