Abstract
To improve a quality of the steel plates in the hot rolling process is an important objective of research. The flying touch hot rolling process is the method that controls the gap between the rolling rolls when the steel plate is transported through rolling rolls. If the steel plate is processed in hot rolling process when the gap between rolling rolls is fixed, the steel plate is damaged by friction and it occurs scratch. So it needs to control precisely the gap and angular velocity of rolling rolls to minimize the friction between steel plate and rolling rolls.
