Rudakova S. Calcium input modes perfection at out-of-furnace processing of low-sulfur basic oxygen steel.

3. The physical simulation of circulating flow in casting ladle in conformity with conditions of silicocalcium injection is carried out, the averaged circulating flow of metal simulator is developed. The mass exchange simulator on border of "calcium fumes bubble- melt" separation, based on results of circulating flow in casting ladle research is developed. Calcium assimilability degree and calcium utilization degree calculations in conformity with conditions of calcium injection or calcium input by powder wire are carried out. The complex simulation including powder wire furnacing and its trajectory in melt calculation is developed also. The optimum mode of steel processing by powder wire with silicocalcium is offered, the data correlation of calculation to experimental data results is carried out. The statistical examination of liquid steel modifying and desulphuration by calcium features is carried out.
