Generally speaking, cored wire technology is a kind of refining method, as the progress of science and technology, it emerged as the times require. Alloy cored wire has a lot of uses, such as purify the molten steel, make inclusions denature, reduce costs and so on.
The Technique of Alloy Cored Wire
It has many techniques of alloy cored wire, these are as follows:
Firstly, it can make inclusions come-up promptly with excellent purification effect for molten steel and avoids secondary oxidation. Additionally, it can improve the yield of alloy and adjust composition of steel easily. Moreover, it is operated by equipment, thus, maintenance is easier and safer relatively than others, at the same time, it is environmentally-friendly and generate less contaminants to surroundings.
From above, we can see clearly that it is a kind of auxiliary method. It consummates performance of molten steel by this method. Frankly speaking, it is effective for enterprises to reduce their costs during making steel process, notwithstanding costs is reduced slightly.
The Effect of Pure Calcium Cored Wire
When it comes to pure calcium cored wire, we should talk about its effects.
It can make temperature reduce 3 degree centigrade approximately and shorten wire feeding time during producing process of low carbon and silicon steel. In addition, it can improve the utilizing efficiency. For example, feeding amount of pure calcium cored wire is less than iron-calcium cored wire(CaFe cored wire) if you want to get same calcium content. From level of inclusion aspect, the difference is not very obvious between using pure calcium cored wire and iron-calcium cored wire(CaFe cored wire).
Merits of Solid Calcium Cored Wire
- Lower costs and feeding weight of solid calcium cored wire;
- Relieve work pressure for steel mill’s worker;
- Consummate the phenomenon that clogs the nozzle;
- Improve calcium recovery, after plenty of steel mills using solid calcium cored wire we produced, average calcium recovery can reach to 17% approximately.
