Must pay attention to the problems in the use of steel-making silicon aluminum barium calcium!

Silicon aluminum barium calcium high efficiency deoxidizer is an auxiliary material for steelmaking. It is suitable for deoxidation of various forms of steelmaking, especially suitable for deoxidation of converter steelmaking. It has a strong deoxidation and desulfurization effect, can improve the flow performance of molten steel, and solve the problem of nozzle nodules. Reduce gas in steel and reduce inclusions in molten steel. silicon aluminum barium calcium is an ideal deoxidizer and desulfurizer in steelmaking. Calcium has a great affinity for oxygen and sulfur, while silicon has a great affinity for oxygen. Barium not only has a great affinity for oxygen and sulfur, but also barium can effectively reduce the vapor pressure of calcium in the steelmaking temperature range and improve the utilization rate of calcium. The steelmaking deoxidation test shows that the use of silicon calcium barium deoxidation is better than the use of silicon calcium composite deoxidizer.

silicon aluminum barium calcium is the best deoxidizer and desulfurizer in barium-based alloys, which can minimize the oxygen content in steel. At the same time, complex inclusions such as calcium, barium, and aluminum are easy to float from the tank liquid, and pure molten steel improves the impact toughness and processing performance of steel. The use of silicon aluminum barium calcium alloy is better than pure aluminum, ferrosilicon, silicon calcium alloy, and the alloy has a high utilization rate. silicon aluminum barium calcium is not easy to dissolve in molten steel, it can dissolve calcium and reduce the vapor pressure of calcium. In the silicon aluminum barium calcium alloy, the role of calcium in deoxidation and non-metallic inclusion treatment can be fully improved.

It is also important to pay attention to the method and amount of addition of silicon aluminum barium calcium during the steelmaking process. If the addition time is wrong, and the amount is wrong, the final effect will be different! How to use: Add a little bit when there is a bit of molten steel. It is estimated that one-fifth of the tapping is to add a bit of silicon aluminum barium calcium. As the molten steel flows out, add silicon aluminum barium calcium.
