Abstract
The results of thermodynamic calculations and experimental studies of the deoxidation, desulfurization, and modification of low-carbon steel with aluminum and Si–Ca, Si–Sr, and Si–Ba alloys are presented. The metal treatment with silicocalcium leads to the formation of corrosive non-metallic inclusions (CANI). The replacement of calcium-containing alloys with Ba and Sr alloys helps to clean steel from CANI, the formation of smaller complex oxysulfide non-metallic inclusions and a change in the grain size of metal. The calculated data are consistent with the experimental results.
