Pure Calcium Cored Wire Uses

Pure Calcium Cored Wire Applications

It is important to use pure solid cored wire for treating molten alloy, e.g., during the desulfurization process, inclusion control and deoxidation. This wire is produced by encapsulating a calcium metal alloy powder or calcium ferro-alloy in a steel sheath. After that, it's wound on a cold-rolled low carbon sheet to form a cored cable. This type of cored copper wire can provide a more accurate wire feed amount, as well as allowing for a deeper calcium treatment depth.

Comparing the traditional calcium iron cored steel wire to the calcium cored copper wire provides the following advantages

In order to prevent oxidation of the metal, it's important that you weld your sheath. This reduces the amount of oxidation burn loss in the cored-wire and increases the calcium absorption rate into molten steel. Also, it can help to stop the oxidation and leakage of calcium in slag in the welding zones.

Due to the fact that the sheaths are welded together, metal calcium can remain in a liquid state when transported with the molten iron, which reduces the calcium consumption for treating the molten iron. The performance of extruded cored-wires is better than that of wires produced using calcium powder.

It can also be used to treat Aluminum-killed molten Steel Continuous Casting. By modifying both the quantity and the shape of inclusions in the steel, it improves the castability and avoids nozzle obstruction. The cored wire is also used to prevent slag from sticking inside the pouring nozzle. It can improve the quality of cast steel.

The cored wires can also be used to remove impurities from the steel molten to reduce waste and production costs. This can improve welding quality and strength by removing oil, rust, and dirt. If you use cored wires instead of vacuum cleaners that are expensive, it can help to save time and money. Additionally, cored wires are able to remove any unreacted materials from discharged slags and can prevent pollution of the environment. This is a great benefit for foundries with strict environmental laws. Additionally, cored steel wires can be used to introduce a range of chemical elements, such as silicon, sulfur, or nitrogen into molten iron, which will improve its quality.
