Under the conditions of unstable qualitative and quantitative compositions of charge materials, we propose an approach to the selection of programs of bell-less top (BLT) charging. It is based on the reduction of the number of working angular positions of the tray and on the shifts (from batch to batch) of the conditional geometric ridges along the radius of the furnace top. A positive experience of realization of this charging program is shown by an example of blast furnace No. 3 at the Enakievo Iron & Steel Works. We discuss the main specific features of mounting of stationary temperature probes with positive temperature coefficient (PTC) on the blast furnaces, as well as the specific features of temperature distributions along the radius of the furnace for various consumptions of the reduced fuel. The relationship between the temperature over the surface of charge bed and the content of pellets in the charge is established.
