Commissioning underway
Rolling of the first section. Rolling of beams to the XH ® rolling method.
Commissioning Commissioning began at the end of December 2007 with the
rolling of rails with a weight of 60 kg/m. In the weeks and months
thereafter, all the products included in the product mix were, and
still are, rolled.
The rolling mill consists of two 2-high reversing stands and one
universal tandem rolling group with hot saws and one 105-m-long
and 42-m-wide cooling bed. The mill also incorporates the proven
CCS ® stands (Compact Cartridge Stands) for automatic high-speed
changing. The cooling bed is equipped for pre-bending of the rails.
The horizontal/vertical straightening machine located downstream
of the cooling bed completes our supplies.
For rail rolling, the rail and section mill employs the universal rolling
method. It is able to produce rails up to a length of 100 m with
close tolerances for use in high-speed railway systems. Wisco is
now the fourth rail producer in China using technologies and equipment
made by SMS Meer.
