发明名称 PELLETIZED CHROMIUM ADDITION AGENTS FOR FERRO ALLOYS PRODUCTION AND METHOD THEREFOR
摘要 Chromium addition agents which may be advantageously applied in production of chromium-containing alloys can be produced by roasting at 2,350 DEG -2,750 DEG 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.
