Influence of Contents of Carbon and Phosphorous on the Crumbling Phenomena of Si-Al-Fe
首发时间:2012-01-10
Abstract:SiAlFe ferroalloy is widely used as a strong de-oxidation compound to substitute pure aluminum in the production of iron and steel. However, its wide application is limited by the frequent occurrence of self-crumbling phenomena and accompanied emissions of a small amount of toxic and explosive gases. This paper determined the corresponding affecting factors by primary investigation of SiAlFe ferroalloy. Then the influence of contents of carbon and phosphorous on the self-crumbling was studied. The results showed that samples containing more phosphorous crumbled more seriously and the content of phosphorous was suggested to be less than 0.03 wt %. The change of content of carbon did not affect the crumbling obviously, ranging from 0.1~0.7 wt %.
