AHMSA contracts Russula for the design and supply of a
new roller table for the hot strip mill
The new roller table, designed and manufactured by Russula ensures that AHMSA will have a smooth production
during the 2.4 million tons/year hot strip mill installation
The final site of the new mill will be
a couple of meters upstream f r o m
the current mill. Russula was responsible
for the design, supervision
and construction of the new
foundations to support the new
mill.
Since most of the work will be done
with the current mill in operation,
safety is one of Russula’s main concerns.
Therefore Russula has designed,
manufactured and installed
a new support for the roller table
through which production will pass
during the excavation and
construction of the foundations.
To ensure the building can support
the weight of the new hot strip mill
during the equipment transfer operation,
Russula conducted a feasibility
study of the structure to
determine the required modifications
and developed the reinforcement
engineering.
In a couple of months everything
will be ready in Monclova to receive
the mill, and the giant will write
another chapter of his own story.
The large 4-h reversing mill, with 1130
sq in mill posts, utilizes 47 in diameter
work rolls and 60 in diameter backup
rolls. Main drive power is obtained from
two 6000 HP double armature motors
driving through 30 ft long universal
spade and slipper spindles. An entry-side
heavy duty vertical edger is attached to
the main mill housing. The two 43.5 in
caliber type work rolls, sized for 3 in./
pass edging on 10 in slabs are driven by
two vertical mounted 2.000 HP motors
through large universal spindles.
