This research aims to analyze the aluminum alloying process in high-aluminum steel under vacuum conditions.
Conducted theoretical calculations of aluminum vapor pressures at different temperatures.
Monitored aluminum yield as aluminum content varied from 5% to 5.5%.
Analyzed inclusion sizes during smelting in a vacuum induction furnace.
Aluminum yield increased from 89.56% to 95.76% with increased aluminum content from 5% to 5.5%.
Saturated vapor pressures of pure aluminum were 267 Pa, 440 Pa, and 704 Pa at temperatures of 1600 °C, 1650 °C, and 1700 °C.
Fine inclusions (1-5 μm) made up 82.4% of total inclusions, while large inclusions (>20 μm) accounted for only 0.98%.
