Calcium silicon wire is a kind of common steel smelting silicon calcium packet core, the application of this package of core can be avoided when feeding into the other impurities, at the same time, this kind of silicon calcium content in calcium silicon line is more, when use can react with the oxygen in molten steel and other harmful elements, so as to remove it, for the purification of the liquid steel is of great help. The role of silicon calcium line in steelmaking can be more than impurity removal so simple, in order to deepen our understanding of silicon calcium line, let's take a look at its role.
The main raw material of silicon calcium cored wire is silicon calcium powder, which is used as the core material. The outer skin is steel skin, which is pressed by the wire pressing machine.
It can purify the form of steel inclusions, improve the castability of molten steel, improve the service performance of steel, and significantly increase the recovery rate of alloy, reduce the consumption of alloy, reduce the cost of steelmaking, remarkable economic benefit.
Molten steel in smelting, refining process will generate a large number of oxides or deoxidation products, if these oxides are not removed will have a fatal impact on the intrinsic quality of steel, so feed into the liquid steel calcium line, using the strong reducibility of Ca, and deoxidation products to reduce the metal oxides in steel, calcium oxide generation, Or with other oxides in the formation of low melting point complex compounds floating in steel, that is, Ca oxide denaturation, so as to reduce the oxide in steel, purify liquid steel, improve the purity of steel. Solid core si-ca line is easy to control, easy to preserve, low cost of calcium treatment and stable effect of calcium treatment.
Use a circumstance according to different, the type that the place chooses wrap core line also is different, common have solid core to wrap core line, metal to wrap core line, silicon calcium line, carbon line to wait, these products have respective different characteristic. Si-ca wire is also widely used in steel smelting and has a good effect.
