1. Usage
(1)Si-Al-Ba alloy is a new type doxidizer in steelmaking, which can improve inclusion form and reduce the content of gas element in molten steel.
(2) It can replace general alloy and pure aluminum for the final deoxidization in the process of steelmaking.
2. Advantages
(1) Reduce the cost and save aluminum.
(2) It has been proved that it not only meets the deoxidizing requirments of steelmaking, but also has the performance of desulphurization.
(3) It can effectively improve the quality of steel and mechanical properties of steel products.
