Metal calcium wire is mainly used to produce pure calcium cored wire, with compact texture, smooth surface and shiny metal luster; 6.0-8.0mm in diameter; The outer layer is wrapped with plastic paper and packed in a sealed iron barrel with argon, with a barrel of about 170kg.

① High calcium activity, good softness of calcium wire, few joints, and calcium content of more than 97%.

② After the calcium wire is rolled into a solid core calcium wire, other oxides existing in the powder cored wire will not be brought into the calcium treatment process to pollute the molten steel.

③ The calcium wire is more uniform, with higher and more stable active calcium content per meter to ensure more stable calcium treatment effect.
