Title: Preparation of the melting tank for melting magnesite in an electric-arc furnace

Abstract

An average quantitative evaluation of the effect of the fill of crystalline MgO on the main melting characteristics of magnesite in an OKB-955 electric-arc furnace is shown. The diameter of the electrode discharge was 1050 mm and the melting regime was maintained automatically at a voltage of 95-97 V and a current of 6.8 kA. Melting of various grades of magnesite was carried out. The authors found that when a heat-conducting lining is used in the hearth, the yield of first and second grade periclase from the solid melting products is increased 5%. The fairly significant effectiveness of the use of a heat-conducting layer in the hearth lining of a melting tank is demonstrated. This layer makes it possible to improve the technieconomic characteristics of the process and to upgrade the quality of the periclase.
