Calcium Carbide for Steel Desulfurization

High-Efficiency Solid Calcium Carbide for Steel Desulfurization

In modern secondary metallurgy, controlling sulfur content is critical for producing high-grade, clean steel. The use of calcium carbide has long been established as one of the most cost-effective and chemically powerful methods for hot metal pretreatment and steel desulfurization. At Tianjin Zhongying Chemical Co., Ltd., we manufacture high-purity industrial-grade solid calcium carbide engineered specifically to satisfy the rigorous thermodynamic demands of global steelmakers and foundries.

The industrial use of calcium carbide in steel mills demands absolute consistency in particle size and chemical purity. Operating our massive production base in Ordos, Inner Mongolia, Tianjin Zhongying Chemical guarantees:

• Tailored Sizing for Injections: We provide specialized particle sizes (ranging from fine mesh for lance injection to larger lumps for ladle additions) to optimize reaction contact time and prevent material float-off.
• High Gas Yield & Purity: Consistent acetylene gas yield (up to 305 L/kg) ensures minimal unreacted residue and maximum thermodynamic activity per ton of hot metal treated.
• Safe, Moisture-Proof Packaging: Packed in heavy-duty 50kg, 100kg, or 250kg steel drums sealed under an inert nitrogen atmosphere to guarantee zero moisture contamination during ocean transit.
