Metallurgical Calcium Silicon Cored Wire

Metallurgical Calcium Silicon is a common alloy used in the manufacture of strands of cast iron. Cored wire is made from calcium silicon in a powder form that is subsequently coated with a polymer. The process includes several steps, including a batching procedure, which is repeated until the desired composition is achieved. The final step involves application of the cored wire in cast iron. The following section discusses the main steps of this process.

A highly pure and specialized alloy, Calcium Silicon Cored Wire (CaSiC) is a versatile tool for steelmakers. It can change the form of steel impurities during the refining process. This wire is used to reduce steelmaking costs and improve mechanical properties. This wire is also used to improve the quality of steel. Its main applications are in steelmaking, desulfurization, and deoxidization.

Curvature of the cored wire

Typically, the curve of the metallurgical calcium silicon cored wire is in the shape of a bar. A typical bar has a diameter of about 8.5 mm and a metric weight of about 85 g/m. The shape of the cored wire is determined by a set of criteria. The ratio between the two diameters is usually between 1.3 and 6.2.

Thermal protection of the extruded bar 8

The thermal protection of the extruded bar 8 is provided by a coating of a non-woven synthetic fabric. It is fully impregnated with a neutral petroleum-based compound and is stable for a wide temperature range. The coating is often applied in the factory setting. It is necessary to thoroughly clean the coated material prior to use. It is important to note that this coating may affect the final appearance of the extruded bar.

Application of the cored wire in cast iron

Metallurgical calcium silicon cored wire is a new addition to the field of ferrous casting. The use of this wire increases the yield of magnesium in iron castings. In a continuous casting process, magnesium is incorporated into a liquid iron before it is cast into an object. The resulting solid bar has a high apparent density, which makes it an excellent candidate for use in the production of cast iron.

Injection device for introducing the cored wire into the molten metal bath

A judicious selection of the diameter of the calcium silicon cored wire is essential. The diameter should be between 13 and 15 mm, depending on the application. The thickness should be at least 0.8 mm, which is close to the bottom of the ladle. In addition, the injection speed should be at least 110 m/s. The wire's sheath should be made of polyimide, preferably polyurethane.
