The Chalking Mechanism of High-Basicity Sinter in Low-Temperature Reduction Process
Abstract: The change of microstructure of high-basicity sinter after undergoing low-temperature reduction for 20, 40 and 60 min was observed. The study found that hematite transformed rarely to magne-tite in low-temperature reduction process of sinter, and the sinter’s apparent porosity and volume were almost constant. Further study found that with calcium ferrite decomposing into hematite in low-temperature reduction process, new small pores were generated, and the pores became larger along with the reaction, which resulted in merging of the adjacent pores. After that, the sinter’s structure became loose with big pores, and its intensity decreased, which caused chalking of the sinter in low temperature.
