CachedThis effective slag deoxidation process improves alloy recoveries and increases desulfurization efficiency, while also providing protection to the ladle slagline. Our custom-designed products are available with specific levels of metallic aluminum or silicon to lower the oxidation potential of the ladle slag. This decreases alloy fade and minimizes caster clogging and quality downgrades, resulting in a cost effective and efficient ladle refining process.

Synthetic Slag for Secondary Steelmaking – IspatGuru

Mar 28, 2017 · One of the possibilities for influencing the slag regime is the application of synthetic slags to the ladle slag, formed from slag-making additions during the liquid steel tapping. Synthetic slag practice during secondary steelmaking maximizes the efficiency of the steel refining process by (i) improving steel quality, (ii) improving productivity, (iii) reducing costs, and (iv) protecting the environment (since it removes the need of addition of fluorspar also called fluorite).
