Strip elongation in a continuous annealing furnace is controlled by passing the strip around a first driven roll, thence through a portion of the furnace, thence around a second driven roll, wherein the amount by which the peripheral speed of the second roll exceeds the peripheral speed of the first roll is controlled in order to control strip elongation. Strip elongation is sensed by monitoring roll speeds using precision resolvers. This eliminates the need to measure the strip load.
