Automation of a 5 M Rolling Mill for Thermomechanical Rolling of Heavy Plate

摘要

The rolling processes applied for the manufacture of heavy plate, the so-called normal rolling and thermomechanical rolling, are illustrated. The thermomechanical rolling method is dealt with in consideration of the strategy used in the combination of rolling and cooling rates. Scope of duties and aims of automation as well as setup and mode of operation of the process control system are described. In addition, the project flow is discussed; some of the problems encountered while putting the installation into operation are mentioned.
