Resumo
The evolution of the cooling curve during steel hardening process is essential to
define the mechanical properties and quality of the final material. As these properties vary
considerably depending on the cooling rate it is essential to monitor and control the
temperature evolution in the metal. This paper presents the development of a mathematical
modeling of heat transfer, whose purpose is to generate the temporal evolution of the
temperature in a quenching process of steel tube in which water is used as cooling fluid. In
this modeling the tube is divided into N control volumes. The heat conduction equation is
applied to each control volume and conductive heat transfer rate at the tube surface is
considered equal heat transfer rate between the tube and water by convection. The model
equations are solved by implicit finite volume method. Comparisons between the cooling
curves generated by the model are compared with the corresponding curves obtained
experimentally in the industrial process. The results show that the model reproduces well the
trend of the cooling curve during the process. The results also showed that the cooling curve
obtained with the model is very sensitive to convection heat transfer values between the tube
and water.
