Desulfurizer – High-Efficiency Molten Steel Purification Agent for Ultra-Low Sulfur Steel Production

Desulfurizer is a specialized metallurgical additive formulated for rapid and deep removal of sulfur from molten steel, enabling the production of ultra-low sulfur and high-cleanliness steel grades. Based on calcium compounds, magnesium-based reagents, or composite alkali-metal systems, it delivers exceptional sulfur-binding capacity, high reaction kinetics, and precise control of inclusion morphology.

Produced through advanced material design and controlled processing, our desulfurizer offers consistent composition, optimal particle size distribution, low moisture content, and excellent flowability. It enables efficient sulfur removal in ladle furnaces, RH degassers, and torpedo car treatments, significantly reducing sulfur levels while improving steel ductility, toughness, and hydrogen-induced cracking resistance.

We provide customized formulations (CaO-based, Mg-based, CaO-Mg composites, etc.), tailored injection/wire-feeding solutions, and full-process technical support to meet the stringent demands of pipeline steel, ship plate, pressure vessel steel, and other high-performance steel grades. Committed to innovation and reliability, we serve as your strategic partner in achieving superior steel quality, extended equipment life, and sustainable, cost-effective refining operations.
