Metallurgical Product Description
Seamless pure calcium wire plays a very important role in casting and steelmaking. It can better dissolve and absorb alloy powder. It is a product with a very good utilization rate, energy saving and environmental protection, and very high economic benefits.
The core wire has been used since the 1970s to deal with molten steel. With the surging development of thin plate continuous casting technology in the 1990s, the advantages of the seamless calcium wire have been recognized by the vast majority of steel mills and thus gained in popularity across the world. Nowadays, the market share of pure calcium wire in North America has surpassed 70%, and the European market has also reached 40%, the cored wire has achieved excellent economic and social benefits over the past years.

of the seamless calcium technology
The product is well adaptive in steelmaking deoxidation, which is capable of promoting the calcium treatment related to molten steel more efficiently and stable.
advantages of seamless calcium cored wire
It avoids the introduction of harmful elements (S, P, C, Si) in the powder calcium-cored wire, overcoming the phenomenon that the powder calcium-cored wire is hollow or the core powder weight is uneven, which will affect wire feeding. At the same time, since the cored wire is seamless, it will not bring air into the molten steel, which also reduces splashing after entering the molten steel.
With the help of the wire feeder, the molten steel is input as fast as possible, melting and dissolving deep in the molten steel, playing the role of deoxidation, desulfurization, and removal of inclusions. Simultaneously, the composition can be fine-tuned, increasing the yield of metals, rare earths, and other elements, and is capable of ensuring the stability of the composition. Reduce the amount of precious elements added as well as reduce refining costs.
