Pass Design


The foundation of a successful rolling mill operation is a fine tuned pass design. The pass design is created based on your specific mill layout and product requirements. Quad has improved productivity and quality simply by modifying or replacing existing pass designs.
Quad has designed and commissioned a wide range of products on a variety of mill configurations. This includes standard and special section shapes rolled on continuous, semi-continuous, reversing, 3Hi, universal, rail and rod mills. Materials rolled include carbon steels, special alloy, stainless, titanium, aluminum and other special metals.
Quad uses a scientific approach that includes developing a family tree that optimizes mill operation, reduces change time and minimizes roll inventory requirements. Simulation programs ensure the pass design will work within the limitations of the existing mill layout, mill stand & motor capabilities.
