Abstract

Nucor produces metal grating that is used in industrial flooring. To produce the grating, large coils are cut into smaller strips which are used in the grating. The large coils, also called master coils, are approximately 60,000 pounds in weight, 60 inches in width, and have a 68-inch outside diameter. These coils are difficult to manage due to their size, even when they are cut into smaller strips. Each of these strips is welded to itself to secure them for transfer around the plant. If the coils were not welded they would unwind during transportation. Currently the coils are still on the machine that cuts the coils. While the coils are being welded the slitter line is unable to continue operating. If the welding process was moved off of the slitter line, then the productivity of the slitter line would be increased. The coil cart currently has a clamp that holds the coil on the bed of the cart. The cart transfers the coil from the slitter line to the turnstile where it can be transferred to different locations around the plant. In order to move the un-welded coils from the slitter machine to a different location for welding, an additional clamp will be added to the coil cart. This clamp will be on the opposite side of the existing clamp. This new clamp will allow the coils to be moved away from the slitter line without welding. After being moved away from the slitter line, the coils will be welded so that they are secure and able to be transported. Due to the large size of the design it will be difficult to do any physical testing. The design will be modeled using computer software. The design will be tested using the same software that was used during modeling.
