Study of Metallurgical Properties in the Sintered Ore with Variable SiO₂

Abstract:

The low silicon sintered ores are prepared, where SiO2 content is 4.4%, 4.6%, 4.8%, 5.0% and 5.2%, respectively. Their metallurgical properties are also measured. The results state that the low temperature reduction degradation of low silicon sinter is improved with the SiO2 content increase. With the SiO2 content increasing in low silicon sinter, the reducing index sharply decline, and reduction gradually deteriorate. In the meantime, softening initial temperature gradually reduced, softening interval gradually widened, so exceeded SiO2 content does harm to softening property.
