Patent number: 4942656Abstract: 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.
