Following the electrical equipment and control supply for the 120 ton/hr reheat furnace, Russula supplied a combined dividing shear to the Gerdau plant, in Whitby, Ontario, Canada. In order to optimize performance, Russula offered a complete mechanical and electrical package for the dividing shear, customized with a pinch roll and auxiliary chopping shear.
Russula supplied a new pinch roll, a divide shear, servo actuated diverter and a chopping shear. The mechanical and electrical equipment included the motion controller, drives, servos and new motors. Russula was 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 factory acceptance test of the new combined dividing and cropping shear took place in June, 2019. Within the next two months, the equipment was delivered to the Whitby plant. The installation and commissioning occurred during a plant outage in August, 2019.
