The most important factor in the quality of a steel product is the purity of the raw materials. Pure Calcium Cored Wire is used by the steel industry to carry out essential processes in steelmaking such as desulfurization, deoxidation and inclusion removal. Injecting a cored-wire calcium alloy into the hot steel is how this can be achieved. The cored wire can also be used to regulate the consistency of the slag.
The cored steel wire is comprised of a calcium-metal sheath with an outer steel protective coating. The close integration between the core slag and the calcium coating makes it a cost-effective, highly efficient method of treating steel. The cored wire can be used in any kind of steel production line.
Each method has advantages and disadvantages. It was once common to add the calcium alloy into the ladle. However, this method is not used anymore due to its unstable effect on the steel and cost. One of the more recent techniques involves injecting molten steel with the calcium cored cored through a small nozzle at the end. This method produces steel with a better quality than before.
It is important to note that particle agglomeration poses a significant problem for the steelmaking industry. This can lead to gas trapping and stress accumulation, which in turn reduces the structural strength of any fabricated part. This has a negative impact on the forming capabilities of composite metals and limits their applicability. This is why we developed a new type of cored wire that eliminates particle agglomeration: Hi-Cal (r).
Injecting calcium into the steel at a rapid rate is key for achieving optimum cored-wire treatment. Feeding cored-wires at the right rate will enable the sheaths of wires to reach melt surfaces in the fastest time, and also penetrate the layer of slags to the correct depth. The goal is to absorb the most calcium possible by the melt, reduce power leakage, and eliminate the formation on the surface of the sheath.
