Calcium Cored Wire | Ca ≥ 98.5% High Purity
What is Calcium Cored Wire?
Calcium cored wire is a type of multi-alloy cored wire made from powdered metal calcium as the core, and low-carbon steel strips are used as the sheath. It is formed by pressing with wire drawing equipment and is commonly referred to as "Ca CW." With advancements in steelmaking and casting processes, calcium cored wire has found extensive applications. Due to its rich calcium content, it serves as an effective deoxidizer, desulfurizer, and regulator of trace element content.
Types of Calcium Cored Wire
The primary component of Calcium cored wire is calcium (Ca). It is widely used in both steelmaking and casting processes. The common types of Calcium cored wire include CaSi cored wire, pure calcium cored wire, and ferro titanium cored wire. In steelmaking, Calcium cored wire serves as an excellent deoxidizer, effectively reducing oxides in the molten steel and enhancing the purity of the steel. In casting applications, Calcium cored wire is required to minimize harmful elements such as phosphorus (P) and sulfur (S). These harmful elements can lead to a tendency for white iron in castings or cause internal structure issues, such as honeycombing, which severely impacts the quality of the cast products.
Calcium Cored Wire for Steel
With the continuous advancement of steelmaking technology, calcium cored wire has been widely adopted in the smelting processes of different steel grades. This type of wire is specifically designed as a charge for steelmaking and possesses high deoxidation efficiency. It effectively removes harmful elements from the steel, thereby enhancing the quality of the final product.
The use of calcium cored wire has once again improved the steelmaking process, resulting in increased purity and quality of the steel, while also enhancing its overall performance. Currently, calcium cored wire is extensively used in the smelting of low-carbon steel, rebar, bearing steel, and other special steel materials. In the smelting of these steels, calcium cored wire shows excellent results, significantly reducing deoxidation time and minimizing the amount of raw materials needed. As a result, it boosts the yield of steel, lowers steelmaking costs, and improves the overall profitability of steel mills.
Applications of Calcium Cored Wire
- Effective deoxidation of molten steel.
- Reduction of harmful elements, such as P and S.
