The cored wire, also called the metal calcium wire, is a special kind of wire used in the steel-making industry. It consists of a sheath made of pure metallic calcium and an alloy core. It's widely used for secondary steel refinement processes like deoxidation and desulfurization. The product can be used to reduce clogging, improve calcium recovery and the quality of final products.
It's a very efficient method of adding alloys without using expensive equipment like lance systems. One of its main advantages is the high degree automation. Another one is the slower speed at which the wires are fed. It is also dense and tightly wrapped, which makes it suitable for a long storage time.
Pure Calcium Cored Wire can be used with existing wire feeding machines. Its sheath is made of pure metallic calcium, and the core is a fully smelted alloy with few inclusions. The core is tough and has high tensile strengths. It's also not easily broken. Sheath and core are tightly bound together, preventing the core from falling out of the molten metal during the weld process. It is also densely wrapped with the sheath around the core.
Hi-Cal (r) is thinner than conventional cored wires and has a higher powder filling rate. This is an efficient and economical way to introduce calcium and other elements into steel molten. It is a more safe, reliable and cost-effective alternative than traditional calcium treatment methods like adding CaSi through lances or CaFe.
A solid calcium core can be used instead of a powdered one, which is more eco-friendly and safer. Furthermore, the use of a solid calcium sheath can save production costs, as it allows the user to avoid the additional cost of producing core powder. Moreover, it has the advantage of reducing the overall metallurgical loss caused by evaporation of calcium in the molten steel.
As well as its use in the primary process of steel production, solid-core metals calcium wires are also popular for the removal and deoxidation of inclusions in the secondary metallurgy used to produce ferrochrome. The wire can be used for removing silicon from steel grades with low silica content, which can have a significant impact on the production of high-tech steels. In the rapidly evolving steelmaking industry, pure calcium wire cores are becoming increasingly popular. As a result, the demand for this product is increasing steadily. This is a trend that will likely continue into the future. This market will continue to grow in the near term, and is likely to reach more than 7 percent by 2022.
