1. Calcium ferrite can accelerate lime to dissolve so as not to need fluorite fluxing, thus realize steel making without fluorite. Less lining erosion, less environmental pollution.
2. It is shown that the high temperature cooling zone plays an important role in formation of calcium ferrite and high-basicity sinter.
3. However, assimilation of limonite is better and the capability of creating calcium ferrite is higher by 20% than other ores. The reducibility of limonite is better.
4. Wider range of granularity of iron ore will produce longer the amount of calcium ferrite.
5. For sinter with 25% and 50% MAC fines the iron oxides mainly consisted of hematite and magnetite, the bonding phase were mainly dicalcium silicate, glassiness , and a few amount of calcium ferrite.
6. As to high basicity sinter, the influence of the reduction disappearance of calcium ferrite and hematite on sinter strength is twice higher than the phase transition of calcium orthosilicate.
7. Conditions for the low-temperature sintering technology and formation of acicular calcium ferrite have been found in laboratory test. The process has achieved success in industrial test as well.
8. The influences of the lime's activities on the form of calcium ferrite, the sinter's grade, intensity and yield have been studied in this paper.sentencedict.com
9. The results show that the anti-fracture ability of sinters is determined by fracture toughness of calcium ferrite for sinters with large size calcium ferrite.
10. In final slag, the content of tricalcium silicate increase 60%, the content of calcium ferrite decrease 25%, the microstructure turn from granular into interweave structure.
11. By controlling FeO and quicklime content, and improving the permeability and oxidation atmosphere of the sinter bed, the sinters with calcium ferrite as main binding phase can be produced.
12. The results have shown that the high activity of the lime is favorable for the formation of fine acicular and acicular structure calcium ferrite.
13. The results can be applied to the thermodynamic research of new copper smelting technologies adopting calcium ferrite slag.
