| SILICOCALCIUM barium steelmaking alloy is the Deoxidizer, desulfurizer, both dephosphorization (BaP2, BaP3) the role of the inoculant is casting and modifier. Al-deoxy to a large number of steel into calcium silicate liquid barium alloy steel to remove the aluminum oxide inclusions, a low-calcium aluminate solution penalty, which has a smaller surface area, it is faster Floating rate, liquid steel to the inclusion of a significant reduction in the residual liquid steel in a small spherical inclusions in the calcium aluminate not rolling deformation, unlike aluminum oxide inclusions as the corner chain distribution , thus changing the composition of the mixture and shape, and it could be increased with sexual steel, the processing performance and good mechanical properties. SILICOCALCIUM Barium Barium alloy in the temperature range of steelmaking to reduce the vapor pressure of calcium, calcium increase in the solubility of liquid steel, compared with silicocalcium with calcium silicate barium alloy steel slag as a calcium source added, by adding Even if calcium content is silicocalcium half of the amount, liquid steel of calcium in silicocalcium is about 2 times, and the stability of calcium liquid steel also significantly increased. Since the alloy in the presence of barium and effectively protected the calcium, calcium reduce volatile oxidation of liquid steel to achieve the purpose of calcium handling. |
