Intro to Secondary Steelmaking
In this course we provide short presentations that hit the important points that are developed in more detail in our other training. Go here first if you want to get a good but shorter covering of the basics.

Lesson 1: Basic Concepts
The furnace gives you a huge variation in steel chemistry, slag chemistry, oxygen content, temperature, slag carryover, among other things. The caster needs a specific chemistry, a low oxygen content, a slag that won’t change the steel chemistry, all delivered on time at a temperature with little variation.
We are here to tell you the cheat code.

Lesson 2: Slag Color
What is the Slag Color Telling Me?
A sample off of a pole dipped in the slag can give you an estimate of its chemistry. Experienced operators use slag color to decide how much slag conditioner to add and make decisions about additions while taking into account the state of slag deoxidation. This lesson will give you the background to get you started.

Lesson 3: Practice
In this lesson we look at the factors that influence the costs of slag conditioning (some not-so-obvious), and the factors that influence their effectiveness. Then we’ll review the characteristics of available slag conditioning materials that will be consistently better than others under difficult or optimum conditions. Finally, we’ll look at how and why calcium carbide is best used.
