Improvements in rolling mills.

摘要

In a rolling mill line for rolling rod or bar, each mill stand is located on a wheeled carriage which also has feet projecting outwardly from a pair of opposite sides thereof. In use, the carriage is supported with the feet on a rigid foundation so that the passline of the mill rolls is at a fixed predetermined height above ground level. For roll changing, a lifting rail mechanism lifts the stand off the foundation and the wheels enable the stand to be withdrawn from the line along tracks at ground level.
