STUDY ON REDUCING AND MELTING BEHAVIOR OF MILL SCALE/PETROLEUM COKE BLEND
Self-reducing tests were carried out under isothermal and non-isothermal condition in a muffle furnace, aiming to assess the reduction and melting of a self-reducing blend of mill scale and petroleum coke (85-15% in weight). The products obtained were analyzed by mass loss and wet analysis. Furthe...

| description | Self-reducing tests were carried out under isothermal and non-isothermal condition in a muffle furnace, aiming
to assess the reduction and melting of a self-reducing blend of mill scale and petroleum coke (85-15% in weight).
The products obtained were analyzed by mass loss and wet analysis. Further investigations for the products from the
non-isothermal condition were done by X-ray diffraction, nude eye inspection and carbon analyzer. It was observed
that mass loss fraction and metallization degree are directly related and both increase with time and temperature. In
the non-isothermal maximum mass loss was achieved in 8 minutes, reaching metallization degrees above 90%. It was
observed that the reduction of iron oxide occurs mainly in solid state and the smelting of the samples is directly related to
the iron carburization process. Thus, the use of self-reducing mixtures shows a possible way to recycle mill scale. |
