ABSTRACT:
The plant (10) includes a temperature-equalization furnace (16) and an inlet shears (12) and an outlet shears (17) positioned respectively at the inlet and outlet of the furnace. The furnace is equipped with inlet and outlet doors, and cooled rollers connected to a motor for driving them in an oscillatory motion. In a method of continuous strip rolling using such a plant, in the event of an obstacle in a rolling train (18), the part of slab (20) not yet rolled is sheared by the outlet shears, returned to the furnace and kept there until the obstacle has been removed. During retention in the furnace, the slab is kept in a to-and-fro movement by means of oscillatory rotation of the cooled rollers.
