PFS implements gearbox upgrade to restore cold rolling mill operations

Phu My Flat Steel (PFS), part of Viet Nam Steel Corporation, contracted Danieli Service Vietnam to refurbish the gearbox of its cold rolling mill after a spindle failure affected the gearbox geometry. The refurbishment involved on-site machining using specialized equipment.

To minimize mill downtime, the project was divided into three main phases. First, a laser survey identified the problem and determined corrective actions. Next, a new set of spare gears and bearings, along with custom bushings manufactured in Danieli workshops, were supplied.

The final execution phase, which included on-site gearbox machining to restore geometry and installation of new components, was completed in seven days, including running tests.
