Abstract
The article presents a comparison of the intensity of the heat dissipation from the surface of the plates made of 1.4845 and Armco steel during the air jet cooling process. The comparison was made based on the heat transfer coefficient on cooled surfaces. To do this, it was necessary to conduct experimental tests on a measuring stand, consisting in measuring temperature changes at 36 points inside the cooled plate. The tested plates were heated to a temperature of 900°C and then cooled with air supplied at a pressure of 0.1 MPa. Based on the experimental measurements, the boundary conditions were identified by using a 3D numerical model. The tests showed differences in the cooling intensity of the tested plates. The heat transfer coefficients obtained from the inverse solution indicate the difference in heat dissipation from the cooled surfaces. These differences result from the occurrence of scale formed on the Armco steel surface, as well as from the differences in the thermophysical properties of the tested steels.
