Size: Custom desulfurization agent chemistry grade per hot metal pretreatment or ladle desulfurization design (free engineering on request)
Products Overview
Our Desulfurization Agent is a high-performance auxiliary metallurgical material engineered for hot metal pretreatment and ladle desulfurization of steel mills and iron making plants. Also known as desulfurizer or desulphurisation agent, this product is manufactured by Zhengzhou caihua from precisely formulated blends of magnesium metal, lime (CaO), dolomite, and proprietary catalysts. The product family removes dissolved sulfur from molten iron or molten steel to produce clean steel grades for automotive, pipeline, shipbuilding, and pressure vessel applications. Per Pentaphos industry reference, magnesium-based desulfurization agent has very high sulfur affinity, 85-95 percent desulfurization efficiency, low slag volume, lowest per unit sulfur removed operating cost, low environmental impact, and very fast reaction speed of 5-15 minutes.
The Desulfurization Agent product family is offered in five engineering-proven chemistry grades per Pentaphos industry reference. The Pure Magnesium grade is based on magnesium metal (Mg content 99.8 percent minimum) for injection system service, with Recommended Use: injection systems, Typical Dosage 0.4-0.8 kg/T HM. The Mg-CaO Blend grade is based on 70:30 magnesium to burnt lime ratio for general injection service, with Mg content approximately 70 percent, Recommended Use: general injection, Typical Dosage 0.6-1.0 kg/T HM. The Mg-Dolomite Blend grade is based on magnesium and calcined dolomite for high temperature service, with Mg content approximately 65 percent, Recommended Use: high temperature, Typical Dosage 0.7-1.1 kg/T HM. The Enhanced Yield Mix grade is based on magnesium with proprietary catalysts for low recovery systems service, with Mg content approximately 75 percent, Recommended Use: low recovery systems, Typical Dosage 0.5-0.9 kg/T HM. The Low-Fume Formula grade is based on magnesium with fume suppressants for ventilation limits service, with Mg content approximately 60 percent, Recommended Use: ventilation limits, Typical Dosage 0.8-1.2 kg/T HM.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Desulfurization Agent grade is engineered to ASTM, GB/T, and ISO metallurgical standards.
