The function of silicon and calcium cored wire in steelmaking
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 function of silicon and calcium wire in steelmaking is more than removing impurity. In order to deepen our understanding of silicon and calcium wire, let's have a look at its function.
The main raw material of silicon-calcium cored wire is silicon-calcium powder, which is used as the core material, and the outer skin is steel skin, which is pressed by wire pressing machine.
It is used to purify steel inclusions in steelmaking, improve the castability of molten steel, improve the performance of steel, increase the alloy yield, reduce alloy consumption, reduce steelmaking cost, and bring remarkable economic benefits.
Molten steel in the process of smelting, refining will generate a large number of oxide deoxidizing products or, if you don't remove the oxide will be fatal influence on the immanent quality of steel, therefore to feed calcium in liquid steel line, using the Ca strong reducibility, and deoxidizing products reduction in steel metal oxide, calcium oxide generated, or with other oxides formed easily in the rise in steel of low melting point compound compounds, namely Ca oxide degeneration, thus reducing oxide in steel, purify liquid steel, improve the purity of steel. Solid core silicon calcium wire has the characteristics of easy control, easy preservation, low cost of calcium treatment and stable effect of calcium treatment.
