What is Seamless Pure Calcium Cored Wire?
Another name for calcium-cored wire is solid calcium-cored wire or pure calcium-cored wire. This alloy-cored wire is widely utilized. The inner layer is edge-rolled and filled with calcium granules or Ca-wire, depending on the requirements. The outer layer is covered with a steel strip. The calcium-cored wire is appropriate for the molten steel refining process that involves calcium treatment. Via a wire feeding machine, the calcium-cored wire made by a reputable provider of alloy-cored wire is fed into the molten steel at a speed of 60–120 m/min and an amount of roughly 0.8–1.5 m/t.
One kind of cored wire used in the production of steel is Seamless Pure Calcium Cored Wire. In the steelmaking process, it is mostly utilized for inclusion removal, desulfurization, and deoxidation. Three components comprise the wire: an inner core of pure calcium metal wire, an intermediate protective coating, and an outer steel strip. The wire’s long-lasting resilience and efficiency in the steelmaking process are guaranteed by its seamless design.
The steel industry makes extensive use of pure calcium-cored wire because of its superior desulfurization and deoxidation capabilities. It contributes to the steel’s impurity removal, improving the steel’s quality. Additionally, using pure calcium-cored wire can help cut down on processing expenses and pollutants in the environment.
Usually, a wire-feeding machine is used to feed the wire into the steelmaking process. It comes in a variety of packaging options, such as vertical or horizontal coils on steel or wood pallets, steel cages, or wrapped in PVC stretch foil. It is available in numerous diameters, including as 9mm, 13mm, and 16mm.
Classification of Seamless Pure Calcium Core Wire and Its Technical Indicators
| Component | Ca(%) | Ca-wire(g/m) | Steel strip thickness(mm) | Meter weight of steel strip(g/m) | Core weight(g/m) | Cored wire diameter(mm) |
| Content | 97±1 | 52-58 | 1.0±0.2 | ＜297 | ＜350 | 9-9.5 |
The inner core metal calcium wire, the intermediate protective coating, and the outer steel strip are the three components of a unique technique that is used to weld the seamless solid-core pure calcium wire. In the steelmaking process, it is mostly utilized for inclusion removal, desulfurization, and deoxidation.
Applications of Seamless Pure Calcium Cored Wire
There are various uses for seamless pure calcium cored wire in the production of steel.
- Deoxidation: Melted steel is deoxidized using Pure Calcium Cored Wire. It interacts with the oxygen in the steel to lower the oxygen concentration and enhance the quality and characteristics of the steel.
- Desulfurization: Melted steel can also be desulfurized with the wire. When it reacts with sulphur, the sulphur concentration decreases and the cleanliness and machinability of the steel are enhanced.
- Inclusion Removal: When it comes to extracting inclusions from molten steel, pure calcium cored wire is helpful. Non-metallic impurities called inclusions may have an impact on the mechanical characteristics of steel. The wire helps create calcium sulphide and oxide, which can be used to capture and eliminate these impurities from the steel.
- Steel Treatment: Steel that has been corroded by aluminium is treated using pure calcium cored wire. It contributes to changing the inclusion composition of the steel and raising its general quality.
- Cost Reduction: Using Pure Calcium Cored Wire can help lower costs associated with producing steel. It contributes to maintaining a high calcium recovery rate, which minimises material waste and the need for extra calcium processing.
How to Use Cored Wire in Steelmaking Process?
During the steelmaking process, core-clad wire facilitates the addition of metallurgical ingredients to molten steel. Using the wire feeding mechanism provided by the manufacturer, insert the cored wire vertically into the molten steel or iron. The cored wire and other metallurgical materials will completely melt and undergo a chemical reaction at the proper depth, obviating the requirement for additional ingredients and The air-slag response accelerates the pace at which the metallurgical materials made by the manufacturer absorb energy.
Additionally, core-clad wire can be used for casting, refining, alloying, and purifying molten steel in order to alter inclusions. It has a major impact on lowering casting and steelmaking costs, raising the financial advantages of cast iron and steel, and enhancing the quality of cast iron and steel.
