Troubleshooting Challenge: Mill Removal Circuit Doesn’t Move for Large Rolls (.PDF Download)

    Feb. 19, 2016

    A temper mill had a roll-removal system that operated at the proper speed but had difficulty moving large rolls off the production line. A hydraulic cylinder extended to remove the roll and was controlled by a regenerative circuit to achieve fast, slowdown, and approach speeds. The regen circuit used a pilot-operated proportional valve; its pilot connection was fed by a pressure-reducing valve that limited pilot pressure to 572 psi. The pressure at the connection had been verified...
