SBQ round bars produced in the range from 25 to 127 mm
Timken, USA: PSM ® and bar finishing
section put into operation
Commissioning
Control desk ahead of the PSM ® block
with E+A supplied by SMS Meer.
In September 2008, the Timken Company in
Canton, Ohio, USA, has commissioned new
facilities jointly with SMS Meer to extend its
existing Harrison Steel bar mill. “The facility
will reach full capacity in August 2009,“ says
Tom Moline, Steel Manufacturing Vice-President
of Timken.
The expansion increases the mill capacity, extends the product
size range and improves product quality for the production of SBQ
round bars in the range from 25 to 127 mm. Shortly after commissioning,
tolerances of ½ ASTM were already being achieved reflecting
the high performance ability of the mill and documenting
the precision of the hydraulic roll adjustment systems.
Operation in full swing on the PSM ® block.
One-Family rolling
and free-size rolling
The scope of supply from SMS Meer includes
a 3-roll precision sizing mill (PSM ® )
as well as a bar finishing section with cooling
bed, cut-off and loading facilities. The
PSM ® is arranged downstream of the existing
rolling mill and allows both a standardized
groove to be employed in the
roughing and intermediate trains (one-family
rolling) and the infinitely variable production
of finished sizes by means of roll adjustment
(free-size rolling).
