本文论述研制的检测铁矿石(包括烧结矿、球团矿)还原性的标准设备和温度,还原气体流量、还原气体成份、反应管直径及试样量、试样粒度等工艺参数对还原速度的影响,提出了建立我国铁矿石还原性检测标准方法的主要工艺参数,通过对研究结果的数理统计及处理,建立了计算还原度和还原速率的两个数学方程式。 This article discusses the development of the standard equipment and iron and steel (including sinter, pellet) reduction of the standard equipment and temperature, reducing gas flow, reducing gas composition, the reaction tube diameter and sample size, sample size and other process parameters on the reduction rate The main process parameters for establishing the standard method for the determination of iron ore reduction in our country are put forward. Based on the mathematical statistics and the treatment of the research results, two mathematical equations for calculating the reduction degree and the reduction rate are established.
