Si Al Ba Ca is a new deoxidizer and desulfurizer in barium alloys. It can reduce the oxygen in steel to a low level, and the complex oxides containing silicon, aluminum, barium and calcium formed at the same time are easy to emerge from the molten steel, purify the molten steel, and improve the impact toughness and processing performance of steel. The deoxidation of molten steel is an essential process in steelmaking, and the selection of deoxidizer is very important. There are many kinds of deoxidizers and composite deoxidizers used in steelmaking, but why do you choose silicon aluminum barium calcium alloy? Does it have incomparable advantages over other products?
The deoxidization effect of silicon aluminum barium calcium composite deoxidizer is better than that of silicon aluminum iron+silicon calcium, especially in the deep deoxidization of steel and in the end point post blowing. After deoxidation with silicon aluminum barium calcium, the quality of steel is good, especially in improving the strength index of low alloy steel. The tensile strength of the test results is increased by 10 MPa on average, so the rejects with poor performance caused by low strength in production are greatly reduced. Due to the strong deoxidizing ability of silicon aluminum barium calcium composite deoxidizer, the consumption of deoxidizer is reduced, and the average cost per ton of steel is reduced by about 0.8 yuan. In addition, there may be many factors that lead to the popularity of silicon aluminum barium calcium alloy as a composite deoxidizer
