Abstract
Results of the industrial tests on production development of ferrosilicon aluminum alloy are showed. The made tests on smelting of ferrosilicon aluminum in electric furnaces with 1,2, 5 and 9 MVA showed a basic possibility to receive alloy of FS55А15, FS55А20 and FS65А10 grades with using of the carbonaceous raw materials in Saryadyrsky and Ekibastuz coal fields. The optimum parameters of the smelting process of FS55А15, FS55А20 and FS65А10 alloys were defined at the Ekibastuz mini-plant and “KSP Steel” LLP. The average power consumption varied within the interval of 9,1 - 12 MWh per 1 ton of alloy depending on a smelting grade of alloy. Increase in aluminum content in alloy composition might be with the rising in ash level of carbonaceous raw materials. The smelting process is characterized with hot furnace condition and active release of alloy.
