Alloy Cored Wire Used In Steel Industry
Alloy cored wire feeding technology is a kind of refining technology outside the furnace. It makes alloy cored wires using by different alloy powders and steel strips. At present, it’s the time for wire feeding machine to appear. Worker use wire feeding machine to feed alloy cored wire into the ladle at a certain speed, in order to deoxidize the molten steel, fine-tuning composition, desulphurization, inclusion denaturation and attain the goal that purify the molten steel, make the costs cheaper and improve the intrinsic quality of steel.
With the progress of technology, alloy additives can be fed into molten steel. It solves a lot of problems sharply, such as contact with slag, strong affinity with oxygen, low melting point and so on. Thus, in the recent years, it has developed promptly and spread widely in metallurgical realm. However, on the contrary, the application of this technology has just begun in foundry realm.

Advantage of Alloy Cored Wire
As we mentioned above, wire feeding process and technology can solve many problems sharply whatever it is difficult to solve or solved insufficiently by other present processes. In particular, generally speaking, deoxidation is necessary and pivotal task in steelmaking process. It is hard and forlorn to obtain qualified steel product without deoxidizing, needless to say high-quality product, even if making steel by non-oxidation method. So, it is a very vital process for steelmaking to decrease oxygen content in molten steel.
Some people have such a misunderstanding about deoxidizer, they think deoxidizer has weak affinity with oxygen. But actually, it is not. It has strong affinity with oxygen, otherwise, how does it deoxidize? As a result of small specific gravity of these deoxidizers, it is very hard to feed them into inside of molten steel.
Wire feeding technology can feed the greater deoxidizer into the ladle, such as calcium silicate and others. Frankly speaking, they are difficult to be fed into the depth of molten steel most of the time. It can improve the calcium recovery and absorption rate and consummate the deoxidation effect sharply. In addition to calcium silicate, there are also a lot of deoxidizers to be selected.
It has interaction between the alloy elements and air when it is fed into the ladle and eliminating the alloy elements that added to the steel actually. As for other alloy elements, even if they have passed through the slag phase layer and entered the molten steel, they are also affected by boiling point, density and any other properties. Including, some of them get away from molten steel rapidly and can’t be absorbed.
This is peculiarly true for more active metallic elements or easily vaporized elements. It increases the costs. Besides, it also affects the actual content of alloy elements and makes it fluctuated largely. Thereby it affects the alloy steel’s performance. In the early era, this problem had bothered industry realm for a long time. But now, this problem has been solved perfectly due to progress of technology —— wire feeding technology. Alloy elements can be fed into depth of molten steel, at the same time, it avoids being affected by slag phase and air and contacting with them.
What’s more, the alloy elements have longer time to interaction with molten steel and a larger contact area, as a consequence of melting and absorption of alloy elements under the high pressure situation. In order to guarantee the actual content of alloy elements is accurate, besides high absorption rate, it absorbs more stable. Particularly, in terms of fine adjustment for alloy element composition, wire feeding process can be controlled within close to the analytical error.
