Chromium addition agents which may be advantageously applied in production of chromium-containing alloys can be produced by roasting at 2,350*-2,750* F. a previously pelletized mixture of Cr ore, a binder, carbon and if desired a flux. The pellets produced are hard, internally porous and have a film on the surface thereof consisting of various metal oxides. Mainly carbides of Cr and Fe are found in the inner region of the pellet. |
