The Effect Of Each Element in Calcium Silica-aluminum On The Quality Of Steel

    As a common additive, calcium barium silica-alumina not only has a good deoxidizing effect when used but also can be used as a reducing agent. Calcium barium silica-alumina is a kind of compound deoxidizer, which has a better deoxidation effect compared with a common deoxidizer. The content of other impurities in calcium barium silica-alumina is very small, so when used as a deoxidizer will rarely bring a large number of impurities infiltrated into the steel, so it is loved by steel mills, so what is the impact of various elements in calcium barium silica-alumina on the quality of steel?

       Calcium silicon-aluminum barium is now widely used in the steel industry, calcium silicon-aluminum barium is a kind of ore containing silicon, aluminum, barium, calcium elements, in the steel industry, mainly as a deoxidizer, desulfurization agent, can well improve the liquidity of steel, solve the problem of water mouth tumor. Reduce the gas in steel, reduce steel inclusions.

       Silicon: it can improve the hardness of steel, but plasticity and toughness decline, electrical steel contains a certain amount of silicon, can improve the soft magnetic properties.

       Aluminum: It can refine the grain structure of steel, inhibit the aging of low carbon steel. Improve the toughness of steel at low temperatures, but also to improve the oxidation resistance of steel, improve the wear resistance and fatigue strength of steel.

       Barium, calcium: in the steelmaking temperature range to effectively reduce the vapor pressure of calcium, increase the solubility of calcium in the steel, compared with silicon-calcium alloy, with silicon-aluminum barium calcium alloy as a source of calcium added to the steel, the amount of calcium added even if it is half the amount of silicon-calcium alloy added, the calcium content of the steel is about twice the amount of silicon-calcium alloy, calcium in the steel is also significantly improved.
