Conclusions

The influence of the electrical cycle for melting brucite, of the heat-exchange conditions, and of the design of the OKB-955 furnace on the indices of its operation and the periclase quality, has been established. The thermal balances of the heats were determined and the possibility of thermal engineering action on the processes of melting, solidification, and cooling of the periclase block and also on product quality was shown.

A rational cycle for melting brucite using the ninth voltage step, including periodic reduction of the current and making it possible to improve periclase quality, was developed. To increase the technicoeconomic indices, the cycle developed includes the use for melting of brucite of furnaces with a 2500-mm-diameter shell and with a 1100-mm diameter of decomposition of the electrode, fettling the hearth with hot scree which has accumulated the heat of the previous heat, charging the furnace with comparatively small portions of brucite, and the use of the heat of the exhaust stack gases for heating the next portion of charge to be loaded into the furnace.
