【Abstract】 The effects of temperature,gas composition and pre-treatment on the reduction rate of iron concentrate have been measured.Morever,the whisker growth and sticking phenomenon during the reduction process of iron fines have been observed by use of a scanning electron microscope.In the light of the above results,a significant basis has been provided for determining the prereduction process and operating parameters.更多还原
