Useful Material CaFe Cored Wire

CaFe cored wire is a special material made by mixing metallic calcium with a certain proportion of iron powder, and its main components include 25-35% calcium particles and the rest of the iron powderThis material is made of core-spun wire with strip as the skin, which is usually available in two sizes: Calcium 30 and Calcium 40.

1.The main purpose of CaFe cored wire is to be used as a deoxidation and desulfurization agent in the steelmaking process, which is quickly fed into the molten steel through the wire feeder, melted and dissolved in the depth of the molten steel, which plays a role in reducing the blockage of the nozzle and avoiding the formation of long strips of sulfide inclusions, so as to improve the anisotropy of the steelIn addition, the calcium-iron cored wire can also fine-tune the composition of steel, improve the yield of metals and rare earths and other elements, ensure the stability of the composition, and reduce the amount of precious elements added to reduce the refining costThe use of calcium-iron cored wire is suitable for situations where there are strict requirements for pure steel, such as the production of low-carbon, ultra-low-carbon, low-silicon steel grades, as well as steel grades that have specific requirements for the morphology and quantity of inclusionsBy precisely controlling the composition and optimizing the smelting process, the calcium-iron cored wire plays an important role in steel production, especially in improving the alloy yield, reducing the smelting cost, and shortening the smelting time.
