Recent reports suggest
that increased silicon levels improve ladle desulfurization of aluminum killed steel.
Experiments have been conducted on molten steel to test the effect. Sampling
was done at regular intervals to study the evolution of sulfur, silicon and
aluminum in the steel as a function of time. The results show that silicon can
indeed suppress consumption of aluminum by side reactions other than desulfurization.
