“…The electricity consumption was 13,000-15,000 kWh per 1 tonne of the alloy. Based on the work performed, ferroalloys of the FS60A20, FS55A15, FSAMn, FSABa grades were produced from the coal waste, manganese and barite ores [14][15][16][17].…”

The article presents the results of studies on the production of silicon alloys from the Kentau Combined Heat and Power Plant ash by the computer thermodynamic modeling method using the HSC-6.0-Chemistry software package. The effect of temperature (from 500 °C to 2000 °C) and the amount of carbon (from 30% to 40% of the ash mass) on the equilibrium distribution degree of elements between the condensed and gas phases, the grade of resulting ferroalloys. In the system under consideration, the formation of FeSi25 ferrosilicon occurs in the temperature range of 1500-1530 °C, and FeSi45 ferrosilicon-at the temperature of 1610-1700 °C; FS50 ferrosilicon is formed in the temperature range of 1700-1900 °C in the presence of 30% of carbon. The formation of FeSi45A10 ferrosilicoaluminium is possible at 2000 °C and 30% of carbon, in this case the concentrations of the metals in the alloy are 46.51% of Si, 8.57% of Al; 42.27% of Fe. FeSi45A15 ferrosilicoaluminium is formed in the system at 40% of carbon and 2000 °C; the elements’ concentrations in the alloy are 45.62% of Si, 14.76% of Al, 37.29% of Fe. Processing of 1 tonne of the ash makes it possible to produce 459 kg of FeSi45A10 ferrosilicon

“…В Казахстане впервые в мировой практике стали использовать углистые породы для выплавки комплексного ферросплаваферросиликоалюминия, содержащего от 42.5 до 57.5% кремния и от 7.5 до 22.5% алюминия [1][2][3][4][5]. Несмотря на положительные стороны технологии, она имеет ряд недостатков, в частности, невысокие значения электросопротивления, связанными с использованием в шихте стальной стружки, обладающий высокой проводимостью.…”

The article presents the results of studies on the production of ferrosilicon, ferrosilicoaluminium and Fe-Si-Al ligatures when replacing steel chips with magnetite. The object of research was the carbonaceous rock of the Borly deposit. Thermodynamic modeling was carried out using the HSC-5.1, Chemistry software package of the Finnish metallurgical company Outokumpu, based on the principle of minimizing Gibbs energy, and experimental studies-electric melting in an arc furnace at 1000-1400°C begin to form. It was found that under equilibrium conditions, the interaction of Borly ash components with magnetite and carbon in the presence of silicon oxide with silicon-containing reduction products - Si, SiO, FeSi2, Fe3Si, FeSi, SiC; with an increase in the amount of carbon, the degree of silicon extraction in SiC increases. in the elemental state and decreases- in Fe3Si, FeSi; the degree of silicon extraction into the alloy increases, amounting to at 2000°C and 51% carbon, and the degree of silicon transition into the alloy also increases, amounting to 76.4% at 2100°C and 51% carbon. It is determined that, from Borly ash under equilibrium conditions, it is possible to obtain ferrosilicon grades FeSi15, FeSi25, FeSi45 and FeSi50 in the temperature range 1260-1860°C and ferrosilicoaluminium grades FS45A10 and FS45A15 in the temperature range 1930-2100°C. It has been experimentally established that ferrosilicon of the FeSi60 brand (68.7% Si, 1.3% Al) is formed from the conclusions of the electric melting of coal waste together with magnetite concentrate, quartzite and coke.

“…For the previously mentioned benefits, the complex ferroalloy replaces traditional ferroalloy completely or partially within steel making process. Due to the depletion of the high-quality raw materials, many investigations [6][7][8][9][10] were carried out to develop effective technology for the production of ferroalloys from low grade raw materials and industrial wastes. Trials were carried out to obtain FeSiAl by smelting high-ash carbonaceous rocks with an ash content of 55-70% and solid carbon by dry weight 18-25%, in electric furnaces.…”

This paper deals with the possibility of obtaining FeSiAl complex alloy by carbothermic reduction in a submerged arc furnace using aluminum dross, mill scale and feldspar.Bench scale experiments are carried out to clarify the effect of different variants such as reducing agent, basicity, and mill scale content of the charge on the metallic yield and chemical composition of the produced alloy.It was possible to get FeSiAl alloy containing 22% Si and 18% Al. the results reveal that to obtain such alloy less than 20% mill scale must be involved in the charge and the coke with amount 1 stoichiometric must be used.
