In addressing the challenges of low metallization rate, low dezincification rate and high pulverization rate during the disposal of metallurgical solid waste in converter furnaces, this paper aims to improve the pelletizing characteristics and high-temperature reducibility of pellets by optimizing the composition and structure of the raw materials. Physical property analysis experiments on solid waste dust,along with pelletizing experiments using a disc pelletizer, were conducted to investigate the changes in the pelletizing performance of iron and carbon-containing metallurgical solid waste pellets. Additionally,thermal reduction experiments were performed in a high-temperature reduction furnace to examine the pellets' metallization rate, dezincification rate, and pulverization rate.The findings reveal that optimizing the raw material composition significantly enhances the pelletizing characteristics and high-temperature reducibility of the pellets. Optimal green ball properties were achieved with a binder addition of 6% and water addition of 13%,resulting in a compressive strength of 4.6 N/P, drop strength of 3 times/(0.5 m),and a burst temperature of 442 ℃.Under thermal reduction conditions ranging from 1 100 to 1 150 ℃ and a reduction time of 45 to 60 minutes,the pellets attained a metallization rate of up to 88%,an optimal dezincification rate of up to 96%,and a pulverization rate of 3% to 5%.By refining the raw material structure,the pelletizing characteristics and high-temperature reducibility of metallurgical solid waste pellets can be significantly improved.This approach addresses technical challenges associated with the converter furnace disposal of metallurgical solid waste and provides critical technical support for enhancing the resource utilization of solid waste.
