Abstract

The influence of basicity on the metallurgical performances and reduction characteristics of fired super high-grade magnetite pellets under the simulated shaft furnace gas conditions was investigated. The fired pellets in the basicity range of 0.09 (natural basicity) to 1.00 show superior reducibility and low-temperature disintegration performance. However, in the basicity range of 0.20–0.80, the abnormal swelling of the fired pellets occurs. Improving basicity from 0.09 to 0.40 promotes the generation of low melting point slag phases and lower porosity of fired pellets, and accelerates the growth and densification of hematite crystals, impeding the reduction of hematite particles and the formation of metallic iron shell. In addition, the slags that distribute between the hematite particles absorb the reduction stresses by increased distances between the particles during the reduction process, which leads to the large reduction swelling of pellets.
