Embodiment 1
[0042] Embodiment 1 Preparation and use of carbon manganese spheres of the present invention
[0043]First mix 7% of commercially available polyanionic cellulose sodium, 65% of Guangxi white clay, 15% of commercially available dextrin, and 13% of commercially available sodium carbonate according to the weight ratio to prepare the binding agent, and then mix 50 parts by weight of high-carbon After weighing the ferromanganese powder, 43 parts by weight of carbon powder and 7 parts by weight of the binding agent, the weighed high-carbon ferromanganese powder and carbon powder are respectively sent into the mixing mixer for mixing and stirring, and the mixing time is 2min Finally, add the binder and continue mixing and stirring for 2 minutes, then add water and stir according to 6% of the weight of the raw material high-carbon ferromanganese powder, carbon powder and binder. Send the mixed material into LYQ3.0 ball press machine for pressing, and press it into 5-15mm oval carbon-m...
