Abstract
Multiple pairs of pinch rolls are used to advance a rod product along a pathway following a continuously casting and rolling system. Each pinch roll pair exerts a force normal to the rod of less than the amount necessary to substantially degrade the yield strength characteristics of the finished rod. Multiple driven pinch roll pairs cooperate to advance the rod by compressive engagement and accomplish the work of one or two pairs of pinch rolls to minimize work hardening and/or plastic deformation, which can result in an increase in yield strength. Yield strength characteristics are thus improved while the continuous rod product is still advanced and guided at very high speed along a pathway from a horizontal to a vertical direction.
