Barium in Si-Al barium calcium can effectively reduce the vapor pressure of calcium and increase the solubility of calcium in molten steel within the temperature range of steel making. Compared with si-ca alloy, si-barium si-Ca alloy is used as calcium source to add to the liquid steel, even if the amount of calcium added is half of si-ca alloy, the calcium content in the liquid steel is about two times of si-ca alloy, calcium in the liquid steel is also good upgrade.
In fact, silicon aluminum barium calcium as steelmaking deoxidizer, desulfurizer. In steel making, the oxygen content in liquid steel can be reduced by adding an appropriate amount of silicon, aluminum, barium and calcium, and silicon, aluminum, barium, calcium and other elements in silicon, aluminum and barium calcium generate various oxides, which will float on the surface of liquid steel, providing convenience for purifying liquid steel and indirectly improving the quality of steel. This is the role of silicon aluminum barium calcium, is also widely used in the market for important reasons. Silica-aluminum-barium calcium is now widely used in the steelmaking industry. Silica-aluminum-barium calcium is a kind of ore containing silicon, aluminum, barium and calcium elements. It is mainly used as deoxidizer and desulfurizer in the steelmaking industry, which can well improve the flow performance of molten steel and solve the problem of nozzle nodulation. Reduce gas in steel and liquid steel inclusion. Although there are a lot of elements in silicon aluminum barium calcium, but those harmful to the steel impurities are very few, so the use of silicon aluminum barium calcium as deoxidizer, rarely add impurities to the liquid steel, which is very important in the late deoxidizer selection requirements strict deoxidizer. The calcium in silicon aluminum barium calcium can also provide calcium source supplement for steel in the later stage of steel smelting, so as to improve the calcium content of steel, which has a good help for the wear resistance and toughness of steel. In the purchase of materials should also choose reliable manufacturers, I plant production of material quality assurance.
