<p>Strip elongation in a continuous annealing fumace (30) is controlled by passing the strip (42) around a first driven roll (44), thence through a portion (34) of the furnace, thence around a second driven roll (46). The elongation of the strip is sensed. One method is to sense the amount by which the peripheral speed of the second roll (46) exceeds the peripheral speed of the first roll (44). Roll speeds are monitored by precision resolvers (47), Another method is to utilize a strip width measurement to determine elongation, Mechanisms are used for profiling tension throughout the furnace length. <IMAGE></p> |
