1. Adding core wire in the process of steelmaking can avoid the formation of long sulfide inclusions, so as to improve the anisotropy of steel;
2. With the help of wire feeding machine, the liquid steel can be quickly input to dissolve and dissolve in the depth of the liquid steel, so as to reduce the blockage of the nozzle and play the role of deoxidation, desulfurization and inclusion removal;
3. It can fine-tune the ingredients, improve the yield of metals and rare earth elements, and ensure the stability of ingredients.
4. Reduce the amount of precious elements added and reduce the refining cost.
