Seamless CaFe cored wire
Seamless CaFe cored wire is made by mixing calcium metal with a certain proportion of iron powder. The core wire is composed of a mixture of 25-35% calcium particles and the rest of iron powder, which is made of strip steel. Seamless CaFe cored wire is mainly used as deoxidation and desulfurization agent in steelmaking process.
1. After adding calcium iron wire in the steelmaking process, long strips of sulfide inclusions can be avoided, thus improving the anisotropy of steel.
2. with the help of wire feeding machine quickly input liquid steel, melt and dissolve in the depth of liquid steel, reduce the blockage of the water mouth, play the role of deoxidation, desulfurization and inclusion.
3. other components can be fine-tuned to improve the yield of metals and rare earth and other elements to ensure the stability of the ingredients. Reduce the amount of valuable elements added to reduce refining costs.
The Main Features of CaFe Cored Wire as Following:
The technical performance good and can meet the requirements of high-speed feeding.
Be used as deoxidizer, desulfurizer and de-inclusion, the silicon,hydrogen and nitrogen content of molten steel does not increase after treatment.
Can improve the recovery rate of alloying elements, among which the recovery rate of calcium can reach 12%~19%.
Can stably control the Al and S content of steel, improve the mechanical properties of steel, and significantly improve the transverse impact toughness, plasticity and hot workability of steel.
