In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its re-crystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.

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.
