中文摘要：
通过理论分析和气流布料实验研究气流布料改善烧结料偏析状态的力学原理。研究结果表明：气流布料能够改变具有不同物化性质的颗粒下落速度及运动轨迹,使混合料沿烧结料层达到有序堆积,进而使烧结料产生较好的粒度偏析及固体燃料偏析;在最佳喷吹角度为10·的条件下,当气流速度达到34m/s时,物料开始发生有效偏析;当气流速度达到50m/s时,偏析效果最优。
英文摘要：
The dynamic theory of the air-injection feeding was investigated by theoretical analysis and air-injection feeding test. The results show that the air-injection feeding can change the falling speed and move track of the granules with different physical and chemical characters to make the sinter mix pile up along the sintering bed orderly. In this way,the air-injection feeding has good segregation effect of the size and the solid fuel. At the best blowing angle 10·,materials begin to segregate effectively when airflow velocity is 34 m/s,and materials are segregated most effectively when the velocity is 50 m/s.
