“…These relationships model a viscoplastic behaviour linking the flow stress with temperature, strain and strain rate. The values of the parameters used in the above formulae (A 1 , A 2 , B 1 , B 2 , C 1 , C 2 , n 0 , n ss , m, Q def ) were fitted to stress/strain data obtained through hot plane strain compression tests [13] The roll was modelled as steel working within its elastic response. Table 3 shows the physical constants used in the model for both roll and slab.…”
