By addingaluminum, we can form alumina, then oxygen level in liquid steel is decreased, very low level after just few ppm, this is quite effective. However, there's some price to pay usingaluminum. It forms alumina as a result of the deoxidationprocess, that encourages significant trouble during theprocess, and even for the product.
