3. Thermal energy and its effects

This text is limited to a brief review of the thermal properties of the right-of-way and interpasses in the hot-rolling of flat products, with a supplement on the thermal properties of rolls and their consequences.

3.1 Thermal modeling of hot rolling

3.1.1 Heat generation

Recall the heat equation, assuming conductivity k independent of T for simplicity:

ρC(∂T∂t+vx⋅∂T∂x+vy⋅∂T∂y+vz⋅∂T∂z)=k(∂2T∂x2+∂2T∂y2+∂2T∂z2)+
