This system was developed to deliver greater predictability of endpoint sulfur in desulfurization of iron.  The ESM iron desulfurization co-injection system is a unique combination of specially-designed injection equipment; bulk material handling and storage; field-proven, programmable control instruments; and high-quality magnesium reagents.  This system allows either lime or calcium carbide to be co-injected with magnesium.  Typically, the co-injection system is used to introduce magnesium and other powdered reagents simultaneously into transfer ladles of molten iron.  The objective is to achieve a desired endpoint sulfur level by precisely controlling the injection rate and quality of all reagents.

ESM injection equipment is used with many applications other than iron desulfurization.

Other applications include:

• Steel side injection for alloy trim additions

• Injection of calcium and aluminum based steel desulfurization reagents

• Slag coagulants to improve treating and skimming viscous slags

• Alloy additions used in the aluminum industry

• Additions of slag conditioner and slag modifier reagents
