Melting of magnesia refractory materials in an OKB-955N ore melting furnace

Conclusions The experinece in service of the IKB-955N furnace at Magnesite Plant in melting of different magnesia materials was summarized. The influence of a number of factors, including magnesium oxide content in the charge, on the indices of the melting process, was established.The optimum diameter of decomposition of the electrodes, diameter of reaction zone, and specific surface power in the molten material were determined for the different materials.On the basis of approximation equations of the experimental data a method of approximate evaluation of the basic production parameters of the melting process was proposed.Means of increasing the productivity of ore melting furnaces by selection of the optimum diameter of decomposition of the electrodes, adjustment of the automatic system, reduction of melting time, and increasing the average input power were shown.Translated from Ogneupory, No. 1, pp. 34–38, January, 1990.
