| Abstract | To confirm the effects of AlMnCa and AlMnFe alloys on the deoxidization and modification of Al-2 O-3 inclusions, experiments of 4-heat low carbon and low silicon aluminum killed steels deoxidized by AlMnCa and AlMnFe alloys were done in a MOSi2 furnace at 1 873 K. It is found that the 1(#) AlMnCa alloy has the best ability of deoxidization and modification of Al-2 O-3 inclusions than 2(#) AlMnCa and AlMnFe alloys. Steel A deoxidized by 1(#) AlMnCa alloy has the lowest total oxygen content in the terminal steel, which is 37 x 10(-6). Most of the inclusions in the steel deoxidized by 1(#) AlMnCa alloy are spherical CaO-containing compound inclusions, and 89.1% of them are smaller than 10 mu m. The diameter of the inclusion bigger than 50 mu m is not found in the final steels deoxidized by AlMnCa alloys. Whereas, for the steels deoxidized by AlMnFe alloys, most inclusions in the terminal steel are, Al-2 O-3 or Al-2 O-3-MnO inclusions, and a few of them are spherical, and only 76.8% of them are smaller than 10 mu m. Some inclusions bigger than 50 mu m are found in the steel D deoxidized by AlMnFe alloy. |
| Other Abstract | To confirm the effects of AlMnCa and AIMnFe alloys on the deoxidization and modification of Al2O3 inclu-sions, experiments of 4-heat low carbon and low silicon aluminum killed steels deoxidized by AlMnCa and AlMnFe alloys were done in a MoSi2 furnace at 1 873 K. It is found that the 1# A1MnCa alloy has the best ability of deoxidi-zation and modification of Al2 O3 inclusions than 2# A1MnCa and A1MnFe alloys. Steel A deoxidized by 1# AlMnCa alloy has the lowest total oxygen content in the terminal steel, which is 37 × 10-6. Most of the inclusions in the steel deoxidized by 1# AIMnCa alloy are spherical CaO-containing compound inclusions, and 89. 1% of them are smaller than 10 μm. The diameter of the inclusion bigger than 50 μm is not found in the final steels deoxidized by AlMnCa alloys. Whereas, for the steels deoxidized by AlMnFe alloys, most inclusions in the terminal steel are Al2O3 or Al2O3-MnO inclusions, and a few of them are spherical, and only 76. 8% of them are smaller than 10 μm. Some in-clusions bigger than 50 μm are found in the steel D deoxidized by AlMnFe alloy. |
