Popis:	Various factors affecting the stability of lining elements of the working zone of the open-hearth furnaces at the Azovstal' Works are studied. The main reasons for damage to the open-hearth furnace tanks are deterioration of the quality (high content of SiO2 and CaO) of magnesite powders (Satkinskoe deposit) and exclusion of the high-phosphorus cast iron from the conversion process. Damage to the weld bead and charging layer results from formation and modifying transformations of bicalcium silicate. The improvement of the maintenance procedure, production of new bottoms, and charging of the working zone of the open-hearth furnace with magnesite powders imported from Slovakia (the special chemical composition of these powders prevents formation of bicalcium silicate) adopted at the Azovstal' Works make it possible to increase the stability of the lining, substantially decrease the magnesite powder consumption, and reduce the labor input and time for maintenance.
