Shearing Machines

These machines are used in hot steel rolling mill plants for cutting of end of the angle. The processed curving edge can be trimmed by the square roller from the top and bottom at the same time, the straight line can also be trimmed by the linear gauge from the top and bottom at the same time with fine brightness and smoothness.

Descaling | Lechler

Regarding hot rolling of steel, the quality of the rolled metal surfaces depends to a large extent on effective descaling. In order to avoid surface damage, iron oxide scale layers are therefore removed from the hot steel surface by high-pressure water spraying prior to the actual hot rolling process.
