Abstract
Semisteel , the main by-product of titania slag smelting process of ilmenite concentrate with an electric furnace, is of high sulphur and low carbon. As a result, the semisteel cannot be widely used in the steeling process and the market value is relatively low. In order to enhance the added value of semisteel , a novel process which was based on a rotary disc atomizer was suggested on semisteel to produce iron powders in the present study. The oxidation degree of the obtained iron granules was studied by thermogravimetric analysis (TG) in the mixture gas of nitrogen and hydrogen.
