| titleOfInvention | A method for producing molten steel precipitation deoxidizer by utilizing electrolytic aluminum carbon slag |
| abstract | The invention discloses a method for producing molten steel precipitation deoxidizer by using electrolytic aluminum carbon slag. The carbon slag produced by electrolytic aluminum is processed into particles with a particle size of 100 meshes to 150 meshes by using a ball mill. 5mm, used as aggregate for pelletizing; zeolite composition: SiO 2 60—70, Al 2 O 3 <15, Fe 2 O 3 <1.5, CaO<5, MgO<2, K 2 O<3, Na 2 O<1; Mix the above carbon slag and dehydrated zeolite evenly according to the mass percentage of 65:30, then add 5% MgCl2·6H2O as a binder; press the above materials into 30 by dry powder briquetting machine. ~50mm sphere, and then bake to remove crystal water, the mass percentage of each component of the deoxidizer sphere is: MgO<5, F>20, SiO 2 >15, Na<25, C<20; converter or electric furnace steelmaking At the end, after starting to tap, when the molten steel volume in the ladle reaches about 3 tons, the deoxidizer spheres of this product are added at the same time as the deoxidizing alloy is added with the steel flow, and the rest of the steelmaking process is not changed. |
