Objective
The hearth lining is the most critical region of the blast furnace in terms of campaign life. Its wear is greatly determined by the iron flow pattern in the hearth which is governed by the distribution of the coke bed permeability, the structure and position of the dead man and the casting management technique. The knowledge related to these factors is not sufficient to get the heat flux under control; moreover this lack of knowledge is worsened by a lack of instrumentation in the hearth. The research aims at the development and the application of techniques and model tools that will allow an on-line evaluation of the blast furnace hearth conditions and permeability in order to guarantee a stable furnace operation and to control the refractory wear through early corrective actions.
