At ArcelorMittal Eisenhüttenstadt (Germany), an ongoing project to improve the logistics of transporting slabs between the caster exit and the hot strip mill has been completed. Advanced tracking devices are now connected to the line to sense the location of the slabs. Together with new software, the system ensures the fresh slabs retain as much heat as possible. This reduces the need for heating in the hot strip mill.
The target is to transfer at least 25% of all slabs at a temperature higher than 800°C, and another 15% at a temperature above 400°C. Total energy savings are estimated at 160 terajoules/year and CO2-eq emissions will be reduced by 8,800 tonnes/year.
