本文研究了烧结矿和球团矿试样的还原性、软化性和熔化行为之间的关系。为了能够定量地说明高炉炉料的高温性能,对比并综合了荷重软化试验和还原熔化试验的试验结果。介绍了矿样垂直高度降低,重量损失和无因次的煤气阻力三个函数的分布与温度的关系、并指出三个函数分布相应的0.5分位点,试验表明精确分辨通过软化、熔化或两个过程的结合而产生的压差增高,是很有必要的。
This paper studies the relationship between reducibility, softening and melting behavior of sinter and pellet samples. In order to quantitatively explain the high temperature performance of blast furnace charge, the results of load softening test and reduction melting test are compared and integrated. The relationship between the temperature distribution and the distribution of the three functions of the vertical height of the ore samples, the weight loss and the dimensionless gas resistance is introduced. The corresponding 0.5 points of the three function distributions are pointed out. The experiments show that the accurate resolution can be obtained by softening, melting or two A combination of the resulting increase in the pressure, it is necessary.
