The solid cored calcium aluminum wire is formed by wrapping the calcium wire with the inner aluminum skin and biting the outer steel strip.

① It can improve the yield of calcium, adjust and control easily oxidized elements and trace elements, purify liquid steel, change the properties and morphology of inclusions, and improve the quality of molten steel.

② It can also control the reaction speed, prevent molten steel from splashing, form calcium aluminum composite deoxidation, and achieve the purpose of deep deoxidation.
