Notes

The scheme of arrangement of  finishing stands  permits to roll all

sizes of one profile without roll changing.

The rolled products finishing processes

are mechanized completely.

Cutting of finished

rolled products is performed in accordance with the technological requirements: preliminary – in hot state by hot saws, finished - in cold state by  cold shears.

Processes of rolled products straightening, stacking and banding are mechanized completely.

Cutting  of finished rolled products is performed in accordance with the technological requirements: in hot state by  hot saws and in cold state by  cold shears. Processes of rolled products straightening,  stacking and banding are mechanized completely.

When rolling of  flange profiles universal stands are installed on the place of the horizontal stands.
