| description | Aiming at electrolytic manganese residue in Songtao, sintered bricks were prepared by using shale, limestone and fly ash in coordination with electrolytic manganese residue. With the shale and limestone which are rich in Songtao and the fly ash from the local power plant as ore blending materials in coordination with electrolytic manganese residue, the experiments of briquetting, preheating and roasting were carried out. The results show that the dosage of electrolytic manganese residue can be 50%～70%, and the briquet strength will be reduced when the dosage is too high or too low. In the firing process, the effective solid binding and liquid binding can be obtained, and the briquet cracks due to internal stress gathering can be avoided by adjusting the firing temperature and time. The uneven shrinkage and glass phase of low strength resulting from rapid cooling should be avoided during cooling down. The recommended ratio iselectrolytic manganese residue∶shale∶limestone∶fly ash= 6∶2∶1∶1, and the firing system is as follows: preheating temperature 500 ℃, preheating time 30 min, roasting temperature 1 000 ℃, roasting time 120 min, cooling down in a furnace. At this condition, the roasted briquets with the average strength of 28.84 MPa can be obtained, which reaches the MU25 strength index of common sintered brick, and its leaching toxicity also meets the comprehensive standards of sewage discharge. This study provides a new technical idea for the detoxification and recycle of electrolytic manganese residue in Songtao. |
