The process behind manufacturing bars and profiles in the steel industry utilizes heating and cooling at controlled rates in order to facilitate changes in their geometries, as well as to obtain desired changes in mechanical steel properties.This work develops an experimental procedure to reproduce the thermal behavior tubes over a cooling bed. In literature the experimental results obtained by Damasceno (2004) do not take into account the temperature measurements of the sidewalls and the floor below the bed and storage temperatures within and outside the shed. These failures compromise the claim to validate the mathematical model of Souza (2015) and therefore new measurements were obtained with room temperatures controlled, order to validate the mathematical model of a cooling bed heat treatment of steel mill Vallourec Tubes, located in Belo Horizonte, Brazil.
