A roll mounting system for mounting a roll assembly to a roll pinion arranged in a roll housing or removing the roll assembly from the a roll pinion, the roll mounting system comprising the roll assembly and a roll combination tool, said roll assembly comprising a grooved roll for shaping a hot metal workpiece, a spring, a tapered sleeve, a tapered sleeve removal and torque isolation ring, and a locking and unlocking nut, said spring being arranged between the tapered sleeve and the roll and during mounting the roll assembly to the roll pinion acting to push the roll against a flinger on a roll housing before the tapered sleeve is fully engaged with the roll pinion, said tapered sleeve comprising splines for engaging with matching splines on the roll pinion, said locking and unlocking nut comprising internal threads for engaging with matching threads on the end of the roll pinion; said tapered sleeve removal and torque isolation ring comprising splines engaging with matching splines in the roll combination tool; said roll combination tool comprising a roll assembly holder configured to be to said roll assembly, a roll holding mechanism attached to the roll assembly holder to provide support to the roll assembly when the roll assembly is picked by the roll combination tool, a tapered sleeve holding mechanism attached to the roll combination tool to provide support to the tapered sleeve when the roll assembly is picked up by the roll combination tool; said roll combination tool further comprising a power wrench, and a means to turn the power wrench to supply torque to the locking/unlocking nut for pushing the tapered sleeve onto the roll pinion or unfastening the tapered sleeve from the roll pinion so as to prevent any torque load from being transmitted to a robotic arm or manipulator when connected to a mounting flange of a structure coupled to the roll assembly holder during operation. said roll assembly comprising a grooved roll for shaping a hot metal workpiece, a spring, a tapered sleeve, a tapered sleeve removal and torque isolation ring, and a locking and unlocking nut, said spring being arranged between the tapered sleeve and the roll and during mounting the roll assembly to the roll pinion acting to push the roll against a flinger on a roll housing before the tapered sleeve is fully engaged with the roll pinion, said tapered sleeve comprising splines for engaging with matching splines on the roll pinion, said locking and unlocking nut comprising internal threads for engaging with matching threads on the end of the roll pinion; said tapered sleeve removal and torque isolation ring comprising splines engaging with matching splines in the roll combination tool; said roll combination tool comprising a roll assembly holder configured to be to said roll assembly, a roll holding mechanism attached to the roll assembly holder to provide support to the roll assembly when the roll assembly is picked by the roll combination tool, a tapered sleeve holding mechanism attached to the roll combination tool to provide support to the tapered sleeve when the roll assembly is picked up by the roll combination tool; said roll combination tool further comprising a power wrench, and a means to turn the power wrench to supply torque to the locking/unlocking nut for pushing the tapered sleeve onto the roll pinion or unfastening the tapered sleeve from the roll pinion so as to prevent any torque load from being transmitted to a robotic arm or manipulator when connected to a mounting flange of a structure coupled to the roll assembly holder during operation.
