IN THIS LESSON
How to Win at Secondary Steelmaking
The secondary steelmaking crew is stuck between a furnace that is giving them a huge variation in steel chemistry, slag chemistry, oxygen content, temperature, and amount of slag carryover, among other things. The caster, on the other hand, requires a specific chemistry, a specific and low oxygen content, a slag that won’t change the steel chemistry, and delivered on time at a specific temperature with as little variation as possible.
We are here to tell you the cheat code.
It’s desulfurization. Even if you don’t need it.
If that sounds a little ridiculous, hear us out. Take a look at the PDF file and let us know what you think.
-
Get to know the seven conditions for effective desulfurization.
Understand how the right slag chemistry affects the slag’s physical characteristics.
See how the right slag chemistry and physical characteristics affect ladle life.
See how the right slag chemistry and physical characteristics affects clean steel (nozzle clogging).
Understand what slag conditioners do, and why slag conditioners are better than others.
