An operation in which steel is heated above a critical point or recrystallization temperature for a period of time and then slowly cooled to a cooling rate less than that in still air is called annealing. After the steel is austenitized and rapidly cooled at a rate greater than the critical cooling rate, the supercooled austenite can be transformed into martensite. This operation is called ...

If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. 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.
