At today s demanding condition maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing keep rolls in proper position and stabilize rolls. Vertical rolls are ordinarily not driven on a universal rolling mill. Therefore when trying to apply strong pressure to the flange thickness to make H-shaped steel etc. if the material comes into contact with the vertical roll first it increases the possibility of faulty roll bites.
