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.
Apparatus for advancing a continuous metal rod product from a continuous casting and rolling system along a path of travel comprising at least one inner roll having a periphery over which said rod product passes and a plurality of at least three outer rolls each engageable with said rod product as it passes over the periphery of said at least one inner roll, means for moving said inner roll and said plurality of outer rolls relative to one another so as to apply a light compressive force to the rod product between said inner roll and each of said outer rolls, each of said rolls having a rotational axis and means coupled to at least some of said rolls for rotating such rolls about their respective rotational axes, whereby the rod product is conveyed along said path by the rotation of said rolls and the compressive force applied thereto by said plurality of rolls, comprising a single inner roll, wherein a portion of the periphery of said inner roll defines said path of travel, each outer roll engaging said rod product against the periphery of said inner roll on said path of travel, said moving means comprising means for urging said outer rolls toward the rotational axis of said inner roll to apply thereby a compressive force to said rod product at each of said outer rolls.
A method of conveying a continuous rod product from a continuous casting machine and rolling mill along a path of travel to a coiler comprising the steps of:
