Abstract
Non-coking coal (NC) and petroleum coke (PC) were mixed in different ratios, and then silica (HBS) with different particle sizes was added to the mixture. Composite carbonaceous reducing agent pellets were prepared by cold pressing. The particle size of raw materials was divided into 80–100 mesh (81MR) and 100–200 mesh (12MR). The effects of four kinds of silica particle size ranges, 40–80 mesh (48 M), 80–100 mesh (81 M), 100–200 mesh (12 M), > 200 mesh (20 M), silica contents 0–5%, and molding pressures 5–25 MPa on the cold strength of pellets with different particle sizes were studied. The optimal processing conditions were a forming pressure of 20 MPa, powder particle size of 12MR, and NC: PC ratio of 7: 3. The addition of 2% of 12 M silica increased the pellet strength to over 9 MPa. The morphology and structure of different carbon materials were characterized by FESEM, FTIR, XPS, and XRD. The results showed that the reason for the difference in pellet performance was the degree of occlusion of the internal particle size of the pellets, and the amounts of surface functional groups and graphitization.
