Silicon aluminum barium calcium is an alloy containing silicon, aluminum, barium, and calcium.

 

Silicon-calcium-barium-aluminum is the best deoxidizer and desulfurizer in barium alloys, and the complex oxides containing calcium, barium, silicon, and aluminum formed at the same time are easy to float from the molten steel, purifying the molten steel, and improving the impact toughness and Processability.

Product Usage:

 

Silicon calcium barium aluminum deoxidizer is an auxiliary material for steelmaking. It is suitable for deoxidation of various steelmaking forms, especially for converter steelmaking deoxidation. It has strong deoxidation and desulfurization effects, which can well improve the flow performance of molten steel and solve the problem of nozzle nodules. Reduce the gas in the steel and reduce the inclusion of molten steel. Silicon calcium barium aluminum is an ideal deoxidizer and desulfurizer in steelmaking. Calcium has a great affinity for oxygen and sulfur, silicon also has a great affinity for oxygen, and barium not only has a great affinity for oxygen and sulfur, but also effectively reduces the vapor pressure of calcium within the steelmaking temperature range, increasing the Calcium utilization. Steel-making deoxidation experiments show that the deoxidation effect of using silicon-calcium-barium is better than that of silicon-calcium composite deoxidizer. The formed complex oxides containing calcium, barium and silicon are easy to float from the molten steel, making the molten steel pure. It is widely used in the deoxidation of steel, especially for continuous casting steel, which not only improves the fluidity of the steel, improves the quality of the steel, but also reduces the cost of the steel. In the production of cast iron, silicon calcium barium aluminum deoxidizer is not only an effective inoculant, but also has good deoxidation and desulfurization effects

 

 The results show that the deoxidation of SiAlBaCa alloy can make the total oxygen content of the billet between 9-15ppm; it can reduce the inclusions in the steel (compared with other deoxidizers) by about 75-80%; The distribution in the area shows a downward trend. The reason is that the deoxidation of silicon, aluminum, barium and calcium causes the inclusions to grow and float faster than that of aluminum deoxidation; the number of inclusions can reach a lower level quickly; the inclusions can be changed. The spheroidization effect of inclusions is obvious; it can refine the ferrite grains, improve the impact toughness and processing performance of the steel, improve the fluidity of molten steel, and prevent the nozzle from clogging.

 

Deoxidizing molten steel by using silicon aluminum barium calcium can reduce the steelmaking process (can replace the use of a variety of deoxidizers), improve product quality and reduce production costs.
