Embodiment 1
[0038] 100 parts of iron, 500 parts of manganese, 80 parts of silicon, 20 parts of carbon, 20 parts of titanium carbide, 20 parts of molybdenum, 10 parts of scandium, 5 parts of lanthanum, through the following steps to make ferromanganese alloy:
[0039] S1. Sieve the iron powder so that the particle size of the iron powder is between 200-400 mesh, and sieve the manganese powder so that the particle size of the manganese powder is between 300-400 mesh;
[0040] S2. Put the iron powder, manganese powder and other ingredients that meet the requirements into the ball mill for 2-3 hours and then let it stand for 1 hour;
[0041] S3, vacuum drying;
[0042] S4, sieving;
[0043] S5, 500 degree vacuum sintering for 1 hour, 800 degree vacuum sintering for half an hour, 1100 degree vacuum sintering for half an hour, and 1400 degree vacuum sintering for 2 hours.
[0044]Iron and manganese are the main components of ferromanganese alloy. Too little iron powder will reduce the strengt...
