... and more efficient technologies. However, some foundries still employ this technique, especially on small crucible furnaces. The second most popular degassing technique in historical use—and still used today (2008)—is a simple flux wand or static lance. This can be a steel pipe or, more commonly...

Soda ash, calcium oxide, calcium carbide, or a mixture of these, is injected with air through a lance immersed in hot-metal ladles. Calcium serves as the desulfurizing agent producing calcium sulfide. Sulfur levels of 0.015...
