The advantages and functions of calcium silicon cored wire:
calcium silicon cored wire includes a wire body formed by wrapping the core layer with a shell, which is made of iron material. The core layer is made of cored wire alloy powder, and the wire body is equipped with multiple metal material intervals along the length direction to form negative compartments. The negative compartments are evenly distributed along the length direction of the body, and the negative compartments are made of metal powder with low moisture absorption and no pollution to steel. The outer surface of the shell is equipped with continuous anti slip lines, which are in the form of dots, oblique lines, and herringbone Mesh or spiral shaped. Silicon calcium cored wire has good inclusion modification effect and can reduce or prevent hydrogen addition in steel liquid. The added metal powder such as iron powder or steel powder will not have adverse effects on the quality of steel liquid. It can meet the production needs of steel grades with strict control of [H] content, reduce waste products caused by excessive hydrogen content in steel liquid, and also avoid steel quality defects caused by high hydrogen content, thereby improving the yield of steel and achieving significant economic benefits, Moreover, it can extend the storage time of silicon calcium cored wire, which is beneficial for the production organization and raw material management of steel grades with strict hydrogen content requirements. In addition, there are continuous anti slip lines on the outer surface of the shell, which can improve the friction force between the feeding wheel and the outer skin of the cored wire, thereby smoothly feeding the cored wire into the crystallizer steel water.
