MJW Completes Demolition, Removal and Replacement of Rod Mill Facility at CMC Steel

Between 2023 and 2024, MJW executed a project including both demolition of existing equipment and installation of new equipment at CMC Steel in Baldwin, Florida.

The project began with the demolition of existing rod block entry area equipment including removal of existing belt guards, motors, and belts. The existing rod block entry shear, including gearbox, motor, and metal supports, were also removed, as well as the existing laying head and laying head pinch roll, including gearboxes, motors, and steel support columns and all associated equipment (oil pipes, water pipes, air pipes, anchor belt, etc). MJW demolished and disposed of the existing laying head concrete support structure, as well as the existing floor-level concrete for the new sump/containment area, and the removal of existing water boxes and associated supports, with removal of various air, water, and lubrication oil piping. Finally, the removal of the existing laying head lubrication unit and its heat exchanger, and removal of all associated water and oil piping was executed.

Installation of new equipment included a new CVR shear and new CVR shear motor including laser alignment. A new vertical loop former was installed, as well as a new concrete containment area, new lubrication unit and associated piping. MJW also completed installation of new water box support steel, new water boxes, and water box piping modifications including installation of manual valves, hoses, and pressure gauges.

MJW formed and placed concrete foundations for the new shear and laying head equipment. A new CVH shear and its motor were installed. Installation of a new laying head and its motor along with all associated laser alignment was also completed. MJW modified steel and grating to form walking and working surfaces around the perimeter of new concrete platforms for CVH and laying head equipment.

As the next phase of the project, MJW fabricated and installed new support beams for the laying head dog house as well as the assembly and installation of the laying head dog house onto the new supports. New concrete foundations were formed and placed for a new CVH scrap conveyor. The CVH scrap conveyor was also assembled and installed in its entirety.

Additionally, MJW placed concrete for new lubrication unit containment area and set the CVH lubrication unit (tank, pump, etc.) and heat exchanger in place in the newly constructed concrete containment.

Final work on the project included the installation and connection of all lube oil supply and return piping between all the associated new equipment and the new lubrication unit.

Project execution began during regular work hours, but the critical portion of the project was performed during a 40-day plant outage beginning in July of 2023 on a 24 hour/7 day a week basis and was completed ahead of schedule and under budget in mid-August of 2023.
