Solving the deoxidation problem during stainless steel casting

The final deoxygenation process! Finally, the so-called deoxidizer generally refers to a composite deoxidizer consisting of two or more components. Extensive practice has shown that when a composite deoxidizer contains various elements in molten steel, it not only involves operation and responsibility, but also competes with each other, rather than fighting alone. It can significantly improve the deoxidization efficiency itself. Therefore, in the design of composite deoxidizer products, how to think about 1+1=3 is a very important design element. Of course, there are other important indicators for composite deoxidizers, which may seem insignificant, but are essential. For example, the theory of aluminum deoxidation is particularly good, but the problem is that aluminum has a small proportion of severe combustion losses. What should we do? Now we know that the maximum deoxygenation efficiency can be achieved by adding bulk aluminum to the large container, aluminum to the caisson, and feeding wire to the aluminum wire.

The deoxidation ability of aluminum itself is indisputable, and the insertion of liquid steel at the bottom becomes a key issue. Of course, the deoxidation of stainless steel by aluminum also brings insoluble particles of aluminum oxide. In addition, the deoxidation time of aluminum is very short, so it is quite cautious to use aluminum deoxidation for stainless steel casting.
