It is necessary to plan thoroughly all technological stages and to implement them in strict correspondence with preset parameters in order to achieve and hold the required effi ciency level. Each deviation can lead to defects and rejection of rolls. Especial attention is paid to the process reproducibility to provide meeting the special requirements of customers and to guarantee the quality of products.
