In a rolling mill the improvement of a roll changer for rapidly changing from one set of work rolls to another automatically. The work rolls (and chocks) are raised and lowered on spaced apart first inside rails contacting the chocks supporting the upper work roll from operating position to transfer position in the mill housing spaced from each other so that they independently seek a predetermined drive position, preferably by the balancing means of the rolling mill. The work rolls are removed from and inserted into the rolling mill through windows in the mill housing on spaced apart first inside rails and second outside rails by a guide means and latch means positioned on a transfer bed and shift car positioned adjacent the rolling mill without the uses of additional power means to connect and disconnect the latch means to and from the work rolls. The transfer bed may be movable to raise and lower the work rolls from floor level to transfer level.
