In two ways, depending on the position. For rolls and roll inserts in the continuous casting plant, and for bearings in rolling mills and straightening machines, oil-air lubrication is the technique of choice: it delivers a continuous, finely dosed oil flow, keeps dirt out, and cools at the same time, without forming an oil mist. For isolated points, you install a remote TLSD single-point lubricator with a 1 or 5 metre hose, so the unit itself stays outside the hot zone.
