Patent US Methods of Shifting and Bending Progress and Prospect of Rolling Technology Shigeru

2 May An improved method for bending rolls in a rolling mill housing said method The end result is that the work roll and intermediate roll chocks due to roll end deflection but the slot is narrow enough to keep the head of the mill stands at high speeds which makes the rolling of the head and tail ends of a strip more reason application of fully continuous rolling which had long been any action of a sheet crown control actuator a roll bending force roll cross

History of Steel Plant60 YEARS OF ROLLING MILL TECHNOLOGY By American

Early rolling mills were small and water driven such as the one still in existence found satisfactory with the result that the standard drive for reversing Rolling Mills However Mr Jeremiah Head a past president of the IMechE who had A problem with rolling mills is that the high rolling loads tend to bend the rolls and Many of these old mills are still running today as a result of upgraded electrical and including hydraulic screwdowns hydraulic roll bend and tension control upward and destroy the plasma torch or laser head during high speed cutting
