HOT METAL DESULFURIZATION
OPTA is a world leading provider of customized solutions for iron & hot metal desulfurization.
We supply magnesium-based, calcium carbide-based, and fluidized lime-based carrier reagents, along with blended solutions designed to remove impurities and enhance product quality.
By leveraging deep industry expertise, cutting-edge technology, and advanced technical services, we tailor our solutions to each client’s unique needs. This results in more effective desulfurization, fewer defects in the final product, reduced waste, and improved production efficiency.
Our multi-process additives, customized solutions, injection equipment, and technical services support both Basic Oxygen Furnace (BOF) and Electric Arc Furnace (EAF) facilities and foundry applications.
Injectable Desulfurization Solutions
Magnesium-Based Reagents
High-magnesium-content reagents can be used alone or co-injected with fluidized lime or calcium carbide. When co-injected, these reagents improve desulfurization efficiency, effectively reducing sulfur content and producing cleaner, more refined end products.
Calcium Carbide-Based Reagents
Calcium carbide reacts with sulfur to form calcium sulfide (CaS), which separates from the molten metal. It is often used in conjunction with lime and magnesium in multi-injection processes to reduce reagent consumption and shorten injection time.

Fluidized Lime-Based Carrier
Reagents
Fluidized lime-based carrier reagents serve as both a carrier and a flux, ensuring the even distribution of desulfurizing agents. As a key component of our proprietary blends with calcium carbide and magnesium powders, it is sized and blended to prevent segregation and performs effectively as a mono-injected, sequenced, and co-injected reagent.

Blended Reagents
Blended reagents are engineered combinations of iron oxide, lime, and fluorspar that optimize the efficiency, consistency, and performance of the iron desulfurization process. Whether used in mono-injection or co-injection systems, blended reagents provide greater process control and improved purity.
