Silicon calcium alloy powder is wrapped by strip steel.

① It is suitable for deoxidation and desulfurization in steelmaking, which can improve the performance of steel, improve the plasticity, impact toughness and fluidity of molten steel, and directly enter the molten steel for melting and uniform distribution.

② It not only retains the original deoxidation effect of silicon calcium alloy, but also increases the depth of calcium reflection and improves the yield of calcium.

③ It is beneficial to adjust and control the content of easily oxidized elements and trace elements, greatly improve the alloy yield, reduce the smelting cost, shorten the smelting time and accurately control the composition.

④ It can purify liquid steel and partially change the properties and morphology of inclusions, improve the quality of molten steel and improve the casting state.
