Calcium iron cored wire

Calcium iron cored wire is also called calcium iron alloy cored wire, which is an alloy cored wire made by mixing metal calcium with a certain proportion of iron powder and covering it with a steel strip. The calcium-iron cored wire consists of a mixture of 28%-35% calcium particles and 65%-72% iron powder as the core material, and the inner core is wrapped with a cold-rolled low-carbon steel strip as the sheath. As major iron and steel companies have strict requirements on the form and quantity of low carbon steel, ultra-low carbon steel, low silicon steel, and their inclusions, calcium iron cored wire is generally selected for calcium treatment of pure steel.
