Silicon uptake 3

[Greenleader]

How does steel absorb silicon for alloying during a melt? What form of silicon is added, and under what conditions?
I hope this is an appropriate question for this forum. Thanks, Jerry

I know that FerroSilicon is what we used in the pilot castings lab. I believe the composition was Fe-75%wt Si

Here is a web site that you can use to answer your question;

For small heats and test work we added pure Si metal. The only problem with FeSi is variations in C and B levels. Lumps of pure Si are redily available as 99.95% or better.

There are a lot of FeSi grades. You need to know the amount of Si you are trying to add, the impact of other impurities and the thermal effects (exothermic heating).
