This type of electrode is multi-alloy and has many uses in the steelmaking sector. The wire consists of an encapsulated solid metal calcium core enclosed in a low-carbon sheath. The sheath is welded to the core using longitudinal welding. The sheath is protected from atmospheric gas by this process, which makes it suitable for the steelmaking processes. You can use it to perform a range of tasks during the steelmaking processes including deoxidation.
Due to its ability to react with the oxygen in the molten steel, pure calcium cored wire is ideal for carrying out deoxidation. In this way, it is possible to reduce the oxygen in molten steel. This improves the machinability of the steel and enhances the quality. This can also help to desulfurize the steel, because it has the ability to interact with the amount of sulphur present in the metal. Also, it can be used for removing non-metallic inclusions in the molten metal. These have a detrimental effect on the finished product's mechanical properties.
The decomposition process of silicon and aluminum in molten iron is also improved by using this wire. A pure cored calcium wire will also help reduce the amount of slag produced during the melting process.
In addition, the cored-wires improve overall efficiency in the smelting processes by reducing slag removal. Dies can decrease the time for smelting as well as increase the capacity of a steel mill. In turn, this has resulted in a higher production of quality steel, which drives the growth of cored-wire market.
The advantage of cored wires over other types of reactivity alloys is that they are encapsulated within a protective shell, which makes them easier to handle. The alloy reactivity can be controlled more precisely and the dust and contamination risk is reduced. The full benefit of the alloying element is also realized in finished steel products.
Hi-Cal(r) is a new, innovative cored wire from the Injection Alloys Group that uses a novel sheath technology. Hi-Cal (r) has a thicker sheath than traditional cored wire. This allows for better metallurgical performance. In addition, it can be fed using the same equipment that is used for conventional cored wires, which eliminates the need for expensive lance systems and leads to substantial cost savings. Hi-Cal(r) can be ordered in two diameters: 9 mm and 11.5. The sheath is up to four times as thick as conventional cored cable. This figure shows the powder-to-sheath ratio.
