Gerdau Whitby orders new combined
dividing shear from Russula
Gerdau Long Steel North America, located in Whitby,
Ontario, Canada has placed an order for a new
combined dividing shear. The Gerdau Whitby mill
produces angles, channels, rounds, square reinforcing
and flat bars.
Within the project scope, Russula will supply a new
pinch roll, a divide shear, servo actuated diverter
and a chopping shear. The mechanical and electrical
equipment including the motion controller,
drives, servos and new motors is also included
within the scope of supply. Russula is responsible
for the engineering, installation supervision, commissioning
and production support.
The new 40-ton combined shear is multi-functional
with both crank and flying modes. The shear is
movable. In order to switch between the crank
and flying mode the complete shear assembly can
be moved hydraulically. This feature reduces the
switching time to a few seconds and avoids the laborious
task of coupling and uncoupling the shear
cutting arms.
The new combined dividing shear is scheduled to
be in full operation by the summer of 2019. Taking
advantage of our extensive knowledge of the steel
process and experience in mill revamping, Russula
specialists are equipped to develop equipment that
will improve productivity and mill performance.
Russula has a long-standing relationship with the
Gerdau Whitby plant over the past thirteen years. In
2004, Russula upgraded the bar mill. The upgraded
resulted in an 8% production output increase.
Recently, Russula supplied all the electrical equipment
and control software necessary to upgrade
the 120 tons/hr reheat furnace, such that the mill
complied with international safety standards and
improved plant safety and reliability.
