THE DEVELOPMENT OF CONTROL SYSTEM OF ELECTRIC COLLECTING ROLLER TABLE OF HOT ROLLING BROAD-STRIP MILL
The current control method of electric collecting roller table of hot rolling broad-strip mill provides the required tension in the strip due to the difference between the strip speed and the roller speed. This leads to the increased wear of roll barrels and great replacement costs. The authors suggest the calculation method for the required torque electric collecting roller table with the technological features of the rolling cycles of hot strips. The article contains the control method for electric collecting roller table in order to reduce the wear of barrels rolls. The functional diagram for controlling the electric collecting roller table, which implements the proposed control method, is also developed.
