Direct Reduction Process of Pellet Containing Carbon with Addition of Zn-Pb-Bearing Iron and Steel Plant Dust

摘要: The study on direct reduction process of pellet containing carbon with the addition of Zn-Pb-bearing iron and steel plant dust shows that the reduction time and pellet basicity have obvious effect on the evaporation of lead and final metallization degree of pellet.The reduction temperature has significantl influences on the lead and zinc evaporation ratios and on final metallization degree of pellet. The optimum process parameters obtained are reduction temperature of 1 250 ℃,reduction time of 25 min and pellet basicity of 0.9.
