测定了稀土矿加两种不同碳质还原剂的团块在常温下、773K焙烧后、1 573～ 1 773K分别焙烧后的气孔率与压制压力的关系 ,也测定了这两种团块在焙烧前、773K及 1 2 73～ 1 673K分别焙烧后的抗压强度与焙烧温度和时间的关系。
The relationship between the porosity and the pressing pressure of the rare earth ore plus two different carbonaceous reductant agglomerates after roasting at 773K and 1 573 ~ 1 773K at room temperature was also measured. Before, at 773K and 1 2 73 ~ 1 673K, respectively, after baking the compressive strength and calcination temperature and time.
