Calcium Silicon Cored Wire For High Efficiency Desulfurization

Calcium Silicon Cored Wire for High Efficiency Desulfurization utilizes a deep-feeding method to reach the interior of molten steel, preventing calcium from oxidizing and burning off on the steel surface. This results in a more complete and stable desulfurization reaction, efficiently removing sulfur impurities from the molten steel while simultaneously deoxidizing and modifying inclusions, thus balancing desulfurization effectiveness with improved steel performance.

High-Efficiency Desulfurization, Easier to Meet Standards: Calcium (Ca) has a strong affinity for sulfur (S), forming sparingly soluble CaS (melting point 2450℃) in molten steel at 1500℃, with a solubility of only 0.0015%. Desulfurization efficiency reaches 40-50%, far exceeding traditional desulfurizers.

High Alloy Utilization, Significantly Reduced Costs and Increased Efficiency: Core powder is prepared using a nitrogen-protected airflow pulverization process, preventing premature oxidation of calcium. Combined with precision coating technology, the core powder filling rate is ≥75%, ensuring stable alloy content in every meter of wire.

Environmentally friendly and in line with industry trends: The desulfurization process emits no harmful gases, and the generated CaS and calcium silicate can be recycled as slag, resulting in no secondary pollution. Compared to traditional desulfurization processes, it reduces alloy waste and slag emissions, lowers environmental treatment costs, and aligns with the current metallurgical industry's development trend of "green, low-carbon, energy-saving, and consumption-reducing," helping enterprises achieve green production.

Q1: How is the desulfurization effect of calcium-silicon cored wire better than traditional desulfurizers?

A1: Traditional desulfurizers react on the surface of molten steel, where calcium is easily oxidized and burned off, resulting in low desulfurization efficiency and unstable reactions. This product, through wire feeding, reaches deep into the molten steel, avoiding calcium oxidation, resulting in a more complete desulfurization reaction, increasing efficiency by over 40%, and stabilizing the sulfur content of the molten steel. Simultaneously, it can achieve deoxidation and inclusion modification, improving steel performance.

Q2: Can you customize products according to our specific needs?

A2: Yes! We have a professional R&D and production team that can customize calcium-silicon cored wires of different compositions and specifications according to your production processes, steel types, and desulfurization targets. We also provide technical guidance to ensure the product meets your production needs.

Q3: What is the shelf life of the product? How should it be stored?

A3: The product has a shelf life of 12 months. It should be stored in a dry, ventilated, and cool warehouse, avoiding moisture, rain, and direct sunlight to prevent the core powder from becoming damp. During storage, avoid squeezing and collisions to ensure the wire remains intact.
