Abstract
The state of production of silicocalcium and silicobarium by the carbon-thermal method from lumpy and briquetted charge is considered. It is shown that the use of lumpy charge leads to frequent adjustment of its composition, unstable technological and electrical melting conditions, gradual formation of carbide accretion in the furnace bath, which is an obstacle to the creation of continuous and low waste productions. The use of ore-coal briquettes makes it possible to optimize the chemistry of the reduction of elements with carbon, create favorable conditions for the occurrence of lowtemperature chemical reactions and reduce the energy intensity of the technological process. As a result of the use of orecoal briquettes, it becomes possible to mechanize the loading of the charge into the furnace, eliminate the labor-intensive operations to adjust the composition of the charge, utilize own production waste and organize the waste-free production. The examples of the use of the briquetted charge in a semi-industrial furnace with a capacity of 1.6 MVA are provided.
