Calcium Silicon Cored Wire With Good Ductility

Calcium silicon cored wire is a composite material consisting of a calcium silicon alloy core and an outer metal wire. The core layer is calcium silicon alloy powder, and the outer shell is made of iron or other suitable metal materials. The body of the calcium silicon cored wire may be provided with multiple barrier sections formed of metal materials at intervals along the length direction. These barrier sections are made of metal powder with low moisture absorption and no pollution to steel, and are used to improve the storage stability and use effect of the calcium silicon cored wire. In addition, continuous anti-skid patterns may be provided on the outer surface of the outer shell to increase the friction between the feed wheel and the outer skin of the cored wire, so as to facilitate the smooth feeding of the cored wire into the molten steel in the crystallizer.

The silicon and calcium elements in the calcium-silicon cored wire have strong deoxidation ability, which can effectively remove oxygen from the molten steel and improve the quality of the steel. The calcium-silicon cored wire can change the properties and morphology of inclusions in the molten steel, thereby improving the castability and performance of the molten steel. The use of calcium-silicon cored wire can reduce energy consumption in the smelting process and improve production efficiency. Calcium-silicon cored wire is conducive to adjusting and controlling the content of easily oxidized elements and trace elements, which can significantly improve the alloy yield and reduce smelting costs.

Calcium silicon cored wire is mainly used as a deoxidizer and alloy additive to improve the quality and performance of molten steel. Calcium silicon cored wire can be used to produce various high-quality castings to improve the mechanical properties and corrosion resistance of castings. Calcium silicon cored wire can be used as a refining agent to improve the purity of the metal. Calcium silicon cored wire can be used as an additive to improve the quality of the electroplating layer. The production process of calcium silicon cored wire includes the preparation, coating, and drawing of alloy powder. During the production process, the quality of raw materials and production process parameters need to be strictly controlled to ensure the quality and performance of calcium silicon cored wire. At the same time, the finished product needs to be strictly inspected and tested to meet the application requirements of different fields.
