Pure Calcium Cored Wire Order is an important part of the steelmaking process. It is used in order to add elements such as calcium and silica into the molten steel to achieve certain metallurgical objectives. Cored wires are also used to deoxidize steel, by reducing its concentration in the molten alloy. They also help in desulfurization, by reacting with sulfur in the molten steel to lower its concentration. The cored wires may also be used to remove inclusions, improving the quality and machinability of steel.

The primary difference between standard pure metal and calcium wires is their chemistry. Pure calcium-only wires contain only calcium metal while standard pure metal wires contain both calcium and ferrous. Because of this, the calcium cored wire has a higher reactivity than standard pure metal calcium wire. This allows it react more quickly with the molten metal, increasing its effectiveness.
While the reactivity and melting point of the calcium cored metal wire are high, they are lower than the standard pure metal calcium wire. This is due the fact that it contains more ferrous than standard pure metal calcium wire. Due to this, it needs to be heated at lower temperatures in order for it melt properly.
To make pure calcium cored wire, first, the steel strip is tested for granularity and moisture content. The tested steel strip is then placed into a bin that has an 8-mesh screening to sieve alloy powders if they do not meet granularity specifications. After the alloy powders were screened, the slurry was formed by mixing the pure calcium with the alloy.
To ensure that the slurry has the proper reactivity, it is then wrapped in a layer of insulating material, such as a ceramic fiber blanket. This prevents contamination of the slurry and allows it be injected in the steel. This step is vital to the quality of cored wires, as it helps to reduce the rate that it loses its reactivity. Additionally, it increases the stability of the slurry and makes it more resistant to oxidation. This is very useful for long-term storage. The resulting product will then be rolled into coils and packaged to be shipped. The quality of the steel strips will ultimately determine the performance and quality of the cored wire. This is why it's so important to closely monitor each step of the process.
