Endless Strip Production (ESP)

European flagA new development of thin slab casting and direct rolling is Endless Strip Production (ESP). Construction of an ESP plant by Arvedi started in 2008 in Cremona (Italy). The energy consumption of the process is much lower as compared to conventional rolling operations.  For thin plates, supression cold rolling and annealing provide even largers savings.  Besides reduced energy consumption, the process reduces the amounts of other consumables and improves yield (~98%) (Worrell et al., 2010. p. 99).
