Reduced setup times in the rolling mill generate flexibility which allows shorter leadtimes through continuous casting and hot rolling. Traditionally known as schedule-free rolling, this flexibility allows the rolling mill to handle variations without the need for buffering. Cost models based on system dynamics methodology are used to assess the economic potential. Effects on inventory, energy and work roll consumptions are analysed. The simulation results show that investments in flexible processes can be evaluated with dynamic cost models. There is an opportunity for significant cost reduction, but also lowered environmental impact due to reduced energy consumption.
