Useful Material Seamless Pure Calcium Cored Wire

Seamless pure calcium cored wire is mainly used in the calcium treatment process in the steel industry.Avoid polluting the molten steel: Improve the calcium treatment effect: It has a high-density mandrel rod, the quality is easy to detect, the smaller core surface area makes it have a longer shelf life,.

1.Seamless Pure Calcium Cored Wire：Improved Calcium Recovery: The outer steel shell of the pure calcium wire and the high-density pure calcium mandrel can feed the calcium to the deeper part of the molten steel and stay below the critical depth for a longer period of time, thus achieving a higher calcium recovery rate.Improve the quality of molten steel: through professional wire feeding equipment to insert the cored wire into the ideal position, when the skin of the cored wire is melted, the core can be fully dissolved in the ideal position and produce a chemical reaction, effectively avoid the reaction with air and slag, improve the absorption rate of smelting materials, widely used as deoxidizer, desulfurizer,alloy additives, can change the form of molten steel inclusions, and effectively improve the quality of steelmaking casting products.In addition, the large liquid inclusions formed after calcium treatment are easier to float, thereby reducing the content of Al2O3 in molten steel, improving the pourability of molten steel, and also improving the performance after rolling. After calcium is added to the molten steel, part of it dissolves into the molten steel, part of it volatilizes in the form of steam, and part of it reacts with the Al2O3 inclusions or S in the steel to form impurities.
