Core wire is a composite material made of various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) crushed to a certain size and then made into a composite material of any length using cold rolled low carbon steel strip.
It can purify the form of inclusions, improve the castability of steel, improve the use of steel performance, significantly increase the alloy yield, reduce alloy consumption, reduce the cost of steelmaking, and achieve significant economic benefits.
The technical indexes of cored wire are as follows:
1, plus calcium treatment of liquid steel, steel reaction stability, to avoid secondary oxidation, inclusions floating fast, purification of liquid steel effect is good.
2,Favorable to the fine-tuning control of steel composition.
3, alloy yield has been greatly improved.
4,Feeding wire can avoid bringing gas into the steel.
5,Strong adaptability and wide range of application.
6,Feeding line is operated by equipment, easy to maintain, safe production, no pollution of the environment.
