Study of Metallurgical Properties in the Sintered Ore with Variable Carbon

摘要

The low silicon sintered ores are prepared, where C content is 3.3%, 3.5%, 3.7%, 3.9% and 4.1%, respectively. Their metallurgical properties are also measured. The results state that the low temperature reduction degradation property in low silicon sintered ore is to achieve the best when the carbon content was 3.7%. With increasing carbon content, it has a trend that the low silicon sintered reducing gradually become variation. In this range of carbon content, softening initial temperature exceed 1230°C, the softening interval is less than 120°C, so suitable C content are helpful to improve metallurgical properties for low silicon sintered ore.
