1. Features
Si-Al Alloy is used as a deoxidizer in steelmaking, which can improve inclusion form and reduce the content of gas element in molten steel.
2. Advantages
(1) Improve steel quality, reduce the cost and save aluminum, it is especially applied in continuous casting steel of deoxidizing requirements.
(2) It has been proved that it not only meets the deoxidizing requirments of steelmaking, but also has the performance of desulphurization, in addition have advantages of big specific gravity and strong penetration.
