Solid core calcium silicate wire

The solid core silicon calcium wire is composed of an outer steel strip coated with an inner calcium wire and silicon iron powder.

① When used for liquid steel calcium treatment, the ability of the cored wire to penetrate the molten steel becomes stronger during the wire feeding process, and the yield of metal calcium is greatly improved, which can replace the traditional silicon calcium powder cored wire.

② The introduction of ferrosilicon powder can not only cool the local molten steel, but also improve the solubility of calcium in molten steel, greatly reduce the nitrogen absorption of molten steel and further improve the calcium yield.
