流动 MgO 的小团的减小过程被调查并且与在这的传统的酸的小团相比糊。基于活塞流动概念和试验性的数据,为在管状的反应堆的小团的煤气固体的阶段减小的运动模型试穿(强风炉子, BF ) 被建立,并且减小反应率的方程为小团被给。小团的一系列减小实验被执行验证模型。作为结果,试验性的数据和计算结果被适合很好。因此,这个模型能很好描述煤气固体的阶段减小过程并且计算小团的减小反应率。而且,它能给流动 MgO 的小团的减小反应率(reducibility ) 比在 BF 的传统的酸的小团的好的更好的解释。
The reduction process of MgO-fluxed pellets was investigated and compared with traditional acidic pellets in this paper. Based on the piston flow concept and experimental data, a kinetic model fitting for the gas-solid phase reduction of pellets in tubular reactors (blast furnace, BF) was built up, and the equations of reduction reaction rate were given for pellets. A series of reduction experiments of pellets were carried out to verify the model. As a result, the experimental data and calculated result were fitted well. Therefore, this model can well describe the gas-solid phase reduction process and calculate the reduction reaction rate of pellets. Besides, it can give a better explanation that the reduction reaction rate (reducibility) of MgO-fluxed pellets is better than that of traditional acidic pellets in BF.
