Objectif The control of gas and materials flow near the walls of the shaft as well as of the hearth to reach low and stable heat losses without building thick accretions on the walls should increase the life of blast furnaces.To be studied are: - mathematical models of heat transfer through the cooled walls; - tests on a 2 dimensional model to investigate the formation of the coke/sinter mixed layer. Tests on a 3 dimensional model of hearth; - tests on blast furnace and sinter probings near the walls for a better understanding of the mixed layer, vertical probings near the walls to relate charging with the heat losses, radioactive tracers in iron and slag to demonstrate the influence of stagnant zones.
