Study on Deoxidation Behavior in Molten Steel of Barium Series Complex Alloys

The industrial tests of Ba series alloys deoxidization behavior was conducted in LF/VD refining equipments based on laboratory research It is shown that the total oxygen contents of using SiAlBaCa deoxidization is lower than using Al and FeSiAl deoxidization experiments in each working procedure The deoxidization products of SiAlBaCa easily float out from steel compared with that of Al, accordingly, the amount of inclusions is reduced rapidly to a lower level It is very clear that the morphology of deoxidization products are changed to globular shape in SiAlBaCa deoxidization experiments The modified mechanism of Ba series alloys deoxidization products is also discussed
