Fuse-cast baddeleyite--corundum refractories, which are most resistant to the corrosive effect of silicate melts, are widely used for melting various glasses. However, because of several characteristics, such as a tendency to cause defects in the glass (bubbles, cords, and stones) and the temperature at which the glass phase begins to separate from the refractory, the Bakor-33 and Bakor-41 types of material require further improvement.In order to improve the working characteristics of baddeleyite-corundum refractories, it has been suggested in traditional technology that raw materials of greater purity be used, but this would increase production costs for the refractory articles [2].It was shown in studies carried out at the State Institute of Glass that lower-quality indices for refractories are largely the result of the method used for smelting the materials where graphite electrodes are immersed in the melt [3]. The change to a melting regime where the electrodes are not in contact with the melt and where the conditions are created for the minimum contamination of the melt by carbon-containing impurities has made it possible to obtain, in both laboratory and industrial arc furnaces, materials with the required working characteristics [3, 4].The development of a process for obtaining fuse-case baddeleyite refractories with specified properties also includes a review of the industrial factors (loading of the batch~ productivity of the electric-arc furnace, the number of smelts) and the energy consumption, both of which have a significant effect on the technicoeconomic indices of the process.For the purpose of determining the efficient melting in OKB-2130 industrial furnaces at the Shcherbinsk Electrosmelted Refractory Plant, we studied various conditions for the production of baddeleyite refractories.In the analysis we distinguished the two most characteristic melting regimes, provisionally called reducing (smelting carried out with a low voltage and the electrodes immersed in the melt) and oxidizing (high voltage, which provides stable burning of the open arc between melt and electrodes).In advance we analyzed the reducing regime of melting used at the Shcherbinsk Plant; this is characterized by the following electric parameters: voltage across electrodes 200 V, with a current strength of 6-6.5 kA. This regime is used in the production of articles made from Bakor-33, which contains, %: ZrO2 > 33, SiO~ < 14, Na~O < 1.5, and the remainder Al2Oa. The batch consisted of 40.3% zircon concentrate, 50.9% alumina, 6.7% technical ZrO2, and 2.1% sodium carbonate. In the three-shift working in the OKB-2130 No. 4 furnace, two smeltings per shift were carried out with a load of 3-4 tons of batch per smelt~ In accordance with the industrial standard, the batch was loaded and the electrodes then immersed in the batch left after the previous smelting. The batch was heated and melted down as a result~of heat given out when the current passed between the electrodes through the melt. During the whole melting period, and also when...
