    In this paper we present the main features of an online system for real-time monitoring of the bottom part of the blast furnace. Firstly, monitoring concerns the furnace walls and furnace bottom temperatures measurement and their visualization. Secondly, monitored are the heat flows of the furnace walls and furnace bottom. In the case of two measured temperatures, the heat flow is calculated using multi-layer implicit difference scheme and in the case of only one measured temperature, the heat flow is calculated using a method based on application of fractional-order derivatives. Thirdly, monitored is the theoretical temperature of the blast furnace combustion process in the area of tuyeres.U radu se prikazuju osnovna svojstva on-line sustava za praćenje u realnom vremenu donjeg dijela visoke peći. Prvo, praćenje obuhvaća mjerenje temperatura stijenki i dna visoke peći te njihovu vizualizaciju. Drugo, prate se toplinski tokovi na stijenkama i dnu peći. U slučaju dvaput izmjerene temperature, toplinski tok se računa korištenjem višeslojne implicitne sheme diferencije, a u slučaju samo jednom izmjerene temperature, toplinski tok se računa korištenjem metode koja se temelji na primjeni frakcionalnih derivacija. Treće, prati se teoretska temperatra procesa izgaranja u području otvora za zrak
