Abstract
This device comprises: two pairs of lateral flanges rotatably mounted respectively on a shaft pivoting in the frame of the furnace, each pair of flanges receiving a strip support roll by the agency of removable fastening means; means for driving said pairs of lateral flanges, ensuring that their angular displacement is synchronized during the interchange operations; central buffer provided with raising means, which is designed to shut off the orifice provided in the hearth of the furnace, for carrying out the operations of discharging a roll outwards from the furnace containment at the end of an interchange operation; two raisable buffers, one for each support roll, which may be displaced in a vertical translational movement in order respectively: PA1 to ensure the sealing of the orifice provided in the hearth of the furnace during the roll interchange phase; PA1 to ensure that the rolls are supported when the roll bearings are demounted in order to remove the inoperative roll from the corresponding flanges, and PA1 to carry out the lowering of the inoperative roll in order to release it from its flanges; two carriages which are movable transversely relative to the axis of the furn…
