The 'square–round–oval-dog bone' pass design exposed the lowest quality part of the billet at the slitter, leading to chip formation near the slit surface. Control of sulfur in steel and the use of oil lubrication at the caster reduced the segregation in the billets and subsequently chip off defects at the rolling mill.

If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled.
