| Popis: | The structure, chemical and phase compositions, and process properties of the high-carbon ferrochromium powder produced by grinding the lump pig FKh800 ferroalloy have been examined. The pycnometric and bulk densities of the powder and its compressibility at 600–800 MPa have been determined. It is shown that the content of harmful impurities, S and P, in the FKh800 powder complies with the requirements of GOST 4757–91. The resultant powder consists of complex (Cr, Fe)7C3 carbide and a solid solution of carbon in chromium ferrite. |
