From the author: International competition is forcing steelmakers to examine carefully all facets of their operations. Continuously casting master slabs, which must be ripped longitudinally to meet customer-specified widths, is one approach that offers significant potential for improving productivity and enhancing quality. An important issue in designing master slab casters is determining the width that the caster should be capable of producing. Using several distributions of customer order widths and an established procedure to combine customer order widths into patterns for ripping master slabs, this paper investigates various master slab widths. As the master slab width increases, ripping loss (trim loss and other losses) tends to decline. This tendency is punctuated by peaks and valleys in the loss function. Low points in the loss function seem to occur where on the average two, three, four, etc., pieces could be placed across the master slab. It seems that measures of central tendency in the order distribution are good predictors for master slab caster widths that yield low ripping loss.
