Ebros® system installed in rebar mill
At Hmisho: New technology
increases production by 5 percent
Modernization
At Hmisho Trading Group, Syria, SMS Meer has modernized the
existing rebar rolling mill. Our engineers employed the Ebros®
system for the endless rolling of sections, leading to a significant
increase of the overall annual production by 5 %.
A further benefit of the new system is: less crop-end losses and a
reduced number of short bars, whereby the metal yield is improved
by 1.5 %. Moreover, less labor is required since fewer cobbles
means less transports of non-conforming products.
The new Ebros® system pays off for Hmisho: higher productivity, improved material
yield and constant quality.
Technology from rail construction. SMS
Meer has developed the Ebros® system
under a license agreement with Steel
Plantech, Japan. It is based on the welding
technology employed in the construction
of tracks for high-speed trains. The two
companies have transferred this technology
to steelworks construction: to weld together
consecutive hot billets (1,100 °C) as
they come out of the furnace.
Benefits of endless rolling. This process
makes ”endless rolling” of sections possible,
whereby productivity and material
yield are increased and a higher plant utilization
factor is achieved. At the same
time it ensures a constant product quality.
In the Hmisho mill, billets of 130 mm x 130
mm square and 12 m length are welded
and the billet throughput is 60 t per hour.
Market leader in Syria. The complete rebar
rolling mill of Hmisho equipped with HSD®
(High-Speed Delivery) system was supplied
by SMS Meer in 2007. The annual capacity is
350,000 t and it is the fourth plant which has
been supplied by SMS Meer to Syria.
