针对碳热还原法制取稀土硅铁合金工艺中的内配碳造块的特点 ,选择了纸浆废液为粘结剂 ,对所应用的纸浆废液在不同脱水率条件下的密度、粘度、表面张力等物理化学性质进行了测定 ,给出了具体应用要求。同时 ,对以纸浆废液为粘结剂的内配碳稀土精矿团块的干燥过程进行了研究 ,揭示了其干燥脱水过程 ,给出了干燥工序的参考性工艺参数。
In view of the characteristics of carbon block making in rare earth ferrosilicon alloy by carbothermal reduction method, the paper pulp waste liquid is selected as binder, and the density, viscosity, surface tension of the applied pulp waste liquid under different dehydration rates Other physical and chemical properties were measured, given the specific application requirements. At the same time, the paper studied the drying process of the carbon-containing rare earth concentrate agglomerates with pulp waste as the binder, and revealed the drying process and the reference process parameters of the drying process.
