Description
Summary:Basic characteristics and application examples of the mathematical simulator for reheating process in walking‑beam type furnaces, that has been developed and applied to Usiminas plate mill line at Ipatinga, are shown in this paper. This is a bi-dimensional mathematical model solved by the finite volume method, validated by temperature measurements inside the slab during heating and coded as a visual tool. Among these applications, the following can be highlighted: (i) determination of suitable furnace zone temperatures and residence times for processing steels by accelerated cooling technology; (ii) determination of slab average temperature at discharging as well as at each zone exit, supplying data to be fed to the automation system at the comissioning stage; (iii) analyses of slab thermal distribution through the reheating process, enabling operational optimization.
